description: The Cosmology Large Angular Scale Surveyor (CLASS) experiment aims to map the polarization of the Cosmic Microwave Background (CMB) at angular scales larger than a few degrees. Operating from Cerro Toco in the Atacama Desert of Chile, it will observe over 65% of the sky at 38, 93, 148, and 217 GHz. In this paper we discuss the design, construction, and characterization of the CLASS 38 GHz detector focal plane, the first ever Q-band bolometric polarimeter array.

description: L’enseignement au degré primaire n’est pas chose aisée. On se trouve face à des classes très hétérogènes. Les différences des élèves sont multiples : sociales, culturelles, psychologiques, cognitives, conatives, etc. Les élèves ont tous des niveaux différents dans des domaines différents. Ils n’ont pas encore été partagés comme ils le sont au secondaire. Il est alors nécessaire d’opter pour une pédagogie différenciée. L’objet de cette étude est la différenciation dans le milieu scolaire au moyen des TIC. Les technologies se sont développées drastiquement ces dernières décennies et se sont intégrées dans le milieu de l’enseignement. Leurs plus-values ne sont aujourd’hui plus discutées. Cependant, elles n’ont que rarement été associées au concept de pratique de différenciation. Il sera donc question d’effectuer une étude causale permettant de savoir si ces outils technologiques permettent de différencier dans les classes. Le support numérique traité dans ce travail est un site internet très connu dans le milieu pédagogique romand : gomaths.ch. Il a été question de traiter de son efficacité à l’entraînement au calcul automatisé et plus précisément à la mémorisation des tables de multiplication. Une classe de 5H a utilisé ce dispositif durant cinq semaines à hauteur de dix minutes par semaine. Ces dix minutes ont été consacrées à faire cinq petits tests de deux minutes offrant la possibilité de s’autocorriger et de s’auto-évaluer. Après cinq semaines d’expérimentation, les résultats permettent de constater que cette pratique est bénéfique pour les élèves, car les pourcentages de progression chez les élèves test sont plus élevés que chez les élèves témoins. Mais les résultats sont discutables. On ne peut pas vraiment dire qu’il y a eu homogénéisation des niveaux. Par contre, l’utilisation de ce site web permet de tendre à une égalité des niveaux.

description: Using bolts as shear connectors of the steel-concrete composite beams enables prefabricated assembly and makes it possible to demountable and reuse the prefabricated components. However, studies on the fire resistance of prefabricated demountable composite beams (PDCBs) connected by bolts are limited. In this paper, four full-scale fire resistance tests were conducted to investigate the fire resistance of PDCBs connected by shear bolts with profiled sheet ribs parallel to the steel beam. Test phenomena, heating curves, deformation curves, and critical temperatures of specimens were obtained through fire-resistant tests. Test results show that the shear failure of bolted connectors occurred in the partially connected PDCBs instead of in the fully connected ones. Under the same load ratio, the fire resistance limit of PDCBs with fire protection was 4.4 times that of PDCBs without fire protection. The temperatures of the upper flanges of the steel beams in the PDCBs were overestimated by the existing codes. Moreover, numerical heat transfer analysis was carried out to investigate the effect of steel beam upper flange dimensions and concrete slab thickness on the temperature distribution of the steel beam upper flange. Finally, formulas were proposed for calculating the temperature distribution of the steel beam upper flange, which agrees well with the FEM simulated values.

description: Suite aux divers changements survenus au sein de l’école dès la moitié du XXe siècle, notamment avec l’accès pour tous à l’école rendant les parcours scolaires plus compétitifs, les familles s’investissent toujours plus dans la scolarité de leur enfant et se mobilisent ainsi davantage autour de leur réussite scolaire, perçue comme garante d’un avenir social meilleur. Parmi les nombreuses stratégies possibles utilisées par les familles, l’une d’entre elles, et celle qui nous intéresse tout particulièrement dans ce travail, consiste à recourir à l’accompagnement scolaire, sous forme de cours particuliers, dispensés par des prestataires tiers, communément appelés répétiteurs. L’objectif du présent travail consiste, au travers d’entretiens semi-directifs réalisés auprès des répétiteurs du Service d’Appuis Scolaires (SAS) du Centre Vaudois d’Aide à la Jeunesse (CVAJ), à identifier les types de familles dans lesquelles ils interviennent, les enjeux spécifiques qu’ils identifient, les positionnements qu’adoptent les élèves face à l’appui scolaire, le type de relation que les répétiteurs parviennent à tisser avec l’élève et le rôle qu’ils jouent dans l’appui scolaire. Évoluant à mi-chemin entre l’école et la famille, les répétiteurs tendent à pallier aux lacunes éducatives de chacune de ces deux instances. Leurs tâches principales deviennent alors celles d’apprendre aux élèves à apprendre et de les amener vers l’autonomie.

description: Na2IrO3 is an intriguing material for which spin-orbit coupling plays a key role. Theoretical predictions, so far unverified, have been made that the surface of Na2IrO3 should exhibit a clear signature of the quantum spin Hall effect. We studied the surface of Na2IrO3 using scanning tunneling microscopy and density-functional theory calculations. We observed atomic level resolution of the surface and two types of terminations with different surface periodicity and Na content. By comparing bias-dependent experimental topographic images to simulated images, we determined the detailed atomistic structure of both observed surfaces. One of these reveals a strong relaxation to the surface of Na atoms from the subsurface region two atomic layers below. Such dramatic structural changes at the surface cast doubt on any prediction of surface properties based on bulk electronic structure. Indeed, using spatially resolved tunneling spectroscopy we found no indication of the predicted quantum spin Hall behavior.

description: We report the discovery and Doppler mass measurement of a 7.4-day 2.3-$R_\oplus$ mini-Neptune around a metal-poor K dwarf BD+29 2654 (TOI-2018). Based on a high-resolution Keck/HIRES spectrum, the Gaia parallax, and multi-wavelength photometry from the ultraviolet to the mid-infrared, we found that the host star has $T_{\text{eff}}=4174^{+34}_{-42}$ K, $\log{g}=4.62^{+0.02}_{-0.03}$, $[\text{Fe/H}]=-0.58\pm0.18$, $M_{\ast}=0.57\pm0.02~M_{\odot}$, and $R_{\ast}=0.62\pm0.01~R_{\odot}$. Precise Doppler measurements with Keck/HIRES revealed a planetary mass of $M_{\text{p}}=9.2\pm2.1~M_{\oplus}$ for TOI-2018 b. TOI-2018 b has a mass and radius that are consistent with an Earth-like core with a $\sim1\%$-by-mass hydrogen/helium envelope, or an ice-rock mixture. The mass of TOI-2018 b is close to the threshold for run-away accretion and hence giant planet formation. Such a threshold is predicted to be around 10$M_\oplus$ or lower for a low-metallicity (low-opacity) environment. If TOI-2018 b is a planetary core that failed to undergo run-away accretion, it may underline the reason why giant planets are rare around low-metallicity host stars (one possibility is their shorter disk lifetimes). With a K-band magnitude of 7.1, TOI-2018 b may be a suitable target for transmission spectroscopy with the James Webb Space Telescope. The system is also amenable to metastable Helium observation; the detection of a Helium exosphere would help distinguish between a H/He enveloped planet and a water world.

Quels sont les impacts de la mue sur un élève en cours de musique ?

description: La puberté est une phase de transition, où, sous l’effet de l’augmentation hormonale, les changements physiologiques apparaissent. Le développement des structures respiratoires, résonatrices et phonatoires entraîne des changements de tonalité vocale et l’on assiste au phénomène de mue vocale, plus important chez les garçons. La voix devient plus grave et plus forte. Cette transformation naturelle demande une réhabilitation et une réappropriation de la voix qui traverse une période d’instabilité qui peut parfois agacer ou gêner, car on ne maîtrise pas toujours les dérapages. L’identité de l’individu évolue, liée aux facteurs affectifs et émotionnels qui émergent de ce changement. Des impacts physiologiques et psychologiques sont observés. La voix est le reflet d’une part de notre personnalité. Cet outil, si précieux, nous permet notamment de communiquer des intentions et des émotions et joue donc un rôle important sur le plan social. Par la multiplicité des perspectives qu’elle permet d’envisager, la voix de l’élève est au centre de l’éducation musicale. En tant que professionnelles de la musique, nous souhaitons comprendre ces changements pour agir et apporter des outils pédagogiques. Nous tenterons de trouver des subterfuges possibles en classe à l’approche de ces voix oscillantes dans un contexte individuel et en groupe semi-collectif. Au cours de musique, l’élève doit conduire sa voix en contrôlant plusieurs paramètres tels que le timbre, l’intensité et la hauteur qui exige un travail d’écoute complexe. La bienveillance de l’enseignant en banalisant le phénomène contribue à rassurer l’élève et à le guider dans cette découverte et appropriation. L’exercice devient alors une question de patience et de psychologie. Les conseils techniques vocaux par le biais d’exercices présentés dans ce travail, aideront l’élève en difficulté passagère à explorer sa nouvelle voix. Nous espérerons par ce biais éviter le décrochage parfois irrémédiable dans la vie d’un homme, par rapport aux activités vocales. Même si les bienfaits de notre pédagogie n’interviennent qu’ultérieurement, elle contribuera peut-être à repeupler nos chorales en manque d’hommes.

description: We present the BANYAN All-Sky Survey (BASS) catalog, consisting of 228 new late-type (M4-L6) candidate members of nearby young moving groups (YMGs) with an expected false-positive rate of ~ 13%. This sample includes 79 new candidate young brown dwarfs and 22 planetary-mass objects. These candidates were identified through the first systematic all-sky survey for late-type low-mass stars and brown dwarfs in YMGs. We cross-matched the 2MASS and ALLWISE catalogs outside of the galactic plane to build a sample of 98 970 potential $\geq$ M5 dwarfs in the solar neighborhood and calculated their proper motions with typical precisions of 5-15 mas yr$^{-1}$. We selected highly probable candidate members of several YMGs from this sample using the Bayesian Analysis for Nearby Young AssociatioNs II tool (BANYAN II). We used the most probable statistical distances inferred from BANYAN II to estimate the spectral type and mass of these candidate YMG members. We used this unique sample to show tentative signs of mass segregation in the AB Doradus moving group and the Tucana-Horologium and Columba associations. The BASS sample has already been successful in identifying several new young brown dwarfs in earlier publications, and will be of great interest in studying the initial mass function of YMGs and for the search of exoplanets by direct imaging; the input sample of potential close-by $\geq$ M5 dwarfs will be useful to study the kinematics of low-mass stars and brown dwarfs and search for new proper motion pairs.

description: The study of the static and dynamic behaviour of the architectural heritage of historical-artistic value made up of rigid stone blocks is a topic of particular interest in the field of modern Seismic Engineering. Such knowledge, in fact, is indispensable for the planning of correct maintenance for the conservation of this type of cultural heritage, especially in conditions of natural and human-induced risks. Among these types of artifacts, the Neptune Temple (also called Poseidònion) located inside the Archaeological Park of Paestum (southern Italy) and a case study of this research, is an emblem for the architectural, sculptural, constructional and structural aspects. It is also unique in the international panorama for its state of conservation, still complete of the whole trabeation and the two pediments. The work describes the study and the research in progress in this area, illustrating the main results obtained by in-depth theoretical studies of the static and dynamic behaviour of rigid block, from experimental investigations carried out both in the laboratory and on site. These last were conducted under the patronage of ICOMOS Italia and the Archaeological Park of Paestum. These studies and research have the objective of evaluating the static and dynamic behaviour of the main building blocks of the Temple and, also, evaluating their safety about seismic actions...

description: GJ 229B, the first type-T brown dwarf to be discovered, has presented a tension between comparisons with evolutionary models and the larger-than-expected mass and radius values derived from spectroscopic and astrometric observations. We examine the hypothesis that GJ 229B is actually a binary sub-stellar object by using two grid-based fits using evolutionary models to explore the range of mass ratios of the possible binary components. We find that the best-fit component values are most consistent with a roughly 2:1 binary mass ratio and an age range of 2-6 Gyr. The observed temperatures, masses, and apparent radii match expected values from evolutionary models for a binary much better than a single-object model, but more detailed observations and modeling are needed to definitively confirm the binary hypothesis.

description: We report on the status and development of polarization-sensitive detectors for millimeter-wave applications. The detectors are fabricated on single-crystal silicon, which functions as a low-loss dielectric substrate for the microwave circuitry as well as the supporting membrane for the Transition-Edge Sensor (TES) bolometers. The orthomode transducer (OMT) is realized as a symmetric structure and on-chip filters are employed to define the detection bandwidth. A hybridized integrated enclosure reduces the high-frequency THz mode set that can couple to the TES bolometers. An implementation of the detector architecture at Q-band achieves 90% efficiency in each polarization. The design is scalable in both frequency coverage, 30-300 GHz, and in number of detectors with uniform characteristics. Hence, the detectors are desirable for ground-based or space-borne instruments that require large arrays of efficient background-limited cryogenic detectors.

description: Des observations lors de nos vécus personnels, de nos stages et de situations quotidiennes nous ont conduits au constat que la musique était une discipline touchée par des éléments subjectifs, sociaux, émotionnels et personnels spécifiques. L’enseignement de la musique observé en stage ne respectait ni les directives du PER ni le nombre de périodes assignées par le canton. Nous avons fait une observation pour vérifier si ce cas de figure se retrouvait dans d’autres situations d’enseignement. Etant donné que cela s’est avéré être le cas, nous avons fait une enquête par questionnaire pour tenter de trouver des explications possibles à cette situation de déséquilibre entre le PER et les pratiques professionnelles. Le travail propose des raisons possibles d’une certaine réticence des enseignants par rapport à la musique en tant que discipline malgré un rapport affectif majoritairement positif de la même en tant qu’art. Un des objectifs de ce travail sera de proposer des pistes de remédiation pour palier aux difficultés provoquant ce traitement différent, souvent négligeant de la musique en tant que savoir scolaire.

description: This paper describes our resource-building results for an eight-week JHU Human Language Technology Center of Excellence Summer Camp for Applied Language Exploration (SCALE-2009) on Semantically-Informed Machine Translation. Specifically, we describe the construction of a modality annotation scheme, a modality lexicon, and two automated modality taggers that were built using the lexicon and annotation scheme. Our annotation scheme is based on identifying three components of modality: a trigger, a target and a holder. We describe how our modality lexicon was produced semi-automatically, expanding from an initial hand-selected list of modality trigger words and phrases. The resulting expanded modality lexicon is being made publicly available. We demonstrate that one tagger---a structure-based tagger---results in precision around 86% (depending on genre) for tagging of a standard LDC data set. In a machine translation application, using the structure-based tagger to annotate English modalities on an English-Urdu training corpus improved the translation quality score for Urdu by 0.3 Bleu points in the face of sparse training data.

description: The analysis of the available TESS light curves of $α$ Sex (HD 87887) reveals low-frequency pulsations with a period of about 9.1 hours in this spectroscopic A0 III standard star. The IUE observations in December 1992 reveal large flux variations both in the far UV and in the mid UV which are accompanied by variations of the brightness in the V band recorded by the Fine Error Sensor on board IUE. The ultraviolet variability could be due to an eclipse by an hitherto undetected companion of smaller radius, possibly 2.5 R$_{\odot}$ but this needs confirmation by further monitoring possibly with TESS. An abundance determination yields solar abundances for most elements. Only carbon and strontium are underabundant and titanium, vanadium and barium mildly overabundant. Identification is provided for most of the lines absorbing more than 2% in the optical spectrum of $α$ Sex. Stellar evolution modeling shows that $α$ Sex is near the terminal-age main sequence, and its mass, radius and age are estimated to be $M = 2.57 \pm 0.32$ M$_{\odot}$, $R = 3.07 \pm 0.90$ R$_{\odot}$, $A = 385 \pm 77$ Myr, respectively.

Densities and mass assembly histories of the Milky Way satellites are not a challenge to $Λ$CDM

description: We use the \texttt{GRUMPY} galaxy formation model based on a suite of zoom-in, high-resolution, dissipationless $Λ$ Cold Dark Matter ($Λ$CDM) simulations of the Milky Way (MW) sized haloes to examine total matter density within the half-mass radius of stellar distribution, $ρ_{\rm tot}( 10$, at these early epochs halos that survive as satellites to $z=0$ are located many virial radii away from the MW progenitors and thus do not have a chance to merge with it. Our results show that neither the densities estimated in observed Milky Way satellites nor their mass assembly histories pose a challenge to the $Λ$CDM model. In fact, the broad agreement between density trends with the stellar mass of the observed and model galaxies can be considered as yet another success of the model.

description: We analyze pre-explosion near- and mid-infrared (IR) imaging of the site of SN 2023ixf in the nearby spiral galaxy M101 and characterize the candidate progenitor star. The star displays compelling evidence of variability with a possible period of $\approx$1000 days and an amplitude of $Δm \approx 0.6$ mag in extensive monitoring with the Spitzer Space Telescope since 2004, likely indicative of radial pulsations. Variability consistent with this period is also seen in the near-IR $J$ and $K_{s}$ bands between 2010 and 2023, up to just 10 days before the explosion. Beyond the periodic variability, we do not find evidence for any IR-bright pre-supernova outbursts in this time period. The IR brightness ($M_{K_s} = -10.7$ mag) and color ($J-K_{s} = 1.6$ mag) of the star suggest a luminous and dusty red supergiant. Modeling of the phase-averaged spectral energy distribution (SED) yields constraints on the stellar temperature ($T_{\mathrm{eff}} = 3500_{-1400}^{+800}$ K) and luminosity ($\log L/L_{\odot} = 5.1\pm0.2$). This places the candidate among the most luminous Type II supernova progenitors with direct imaging constraints, with the caveat that many of these rely only on optical measurements. Comparison with stellar evolution models gives an initial mass of $M_{\mathrm{init}} = 17\pm4 M_{\odot}$. We estimate the pre-supernova mass-loss rate of the star between 3 and 19 yr before explosion from the SED modeling at $\dot M \approx 3\times10^{-5}$ to $3\times10^{-4} M_{\odot}$ yr$^{-1}$ for an assumed wind velocity of $v_w = 10$ km s$^{-1}$, perhaps pointing to enhanced mass loss in a pulsation-driven wind.

description: Accurate forecasting is important for cost-effective and efficient monitoring and control of the renewable energy based power generation. Wind based power is one of the most difficult energy to predict accurately, due to the widely varying and unpredictable nature of wind energy. Although Autoregressive (AR) techniques have been widely used to create wind power models, they have shown limited accuracy in forecasting, as well as difficulty in determining the correct parameters for an optimized AR model. In this paper, Constriction Factor Particle Swarm Optimization (CF-PSO) is employed to optimally determine the parameters of an Autoregressive (AR) model for accurate prediction of the wind power output behaviour. Appropriate lag order of the proposed model is selected based on Akaike information criterion. The performance of the proposed PSO based AR model is compared with four well-established approaches; Forward-backward approach, Geometric lattice approach, Least-squares approach and Yule-Walker approach, that are widely used for error minimization of the AR model. To validate the proposed approach, real-life wind power data of \textit{Capital Wind Farm} was obtained from Australian Energy Market Operator. Experimental evaluation based on a number of different datasets demonstrate that the performance of the AR model is significantly improved compared with benchmark methods.

description: The explosive growth of online misinformation, such as false claims, has affected the social behavior of online users. In order to be persuasive and mislead the audience, false claims are made to trigger emotions in their audience. This paper contributes to understanding how misinformation in social media is shaped by investigating the emotional framing that authors of the claims try to create for their audience. We investigate how, firstly, the existence of emotional framing in the claims depends on the topic and credibility of the claims. Secondly, we explore how emotionally framed content triggers emotional response posts by social media users, and how emotions expressed in claims and corresponding users' response posts affect their sharing behavior on social media. Analysis of four data sets covering different topics (politics, health, Syrian war, and COVID-19) reveals that authors shape their claims depending on the topic area to pass targeted emotions to their audience. By analysing responses to claims, we show that the credibility of the claim influences the distribution of emotions that the claim incites in its audience. Moreover, our analysis shows that emotions expressed in the claims are repeated in the users' responses. Finally, the analysis of users' sharing behavior shows that negative emotional framing such as anger, fear, and sadness of false claims leads to more interaction among users than positive emotions. This analysis also reveals that in the claims that trigger happy responses, true claims result in more sharing compared to false claims.

description: This article delves into the complex relationship between language and its speakers, exploring how language functions not only as a tool for conveying thoughts and emotions but also as a powerful marker of identity and cultural heritage. It examines the nature of language as a living system that reflects and adapts to the needs of its speakers, influenced by factors such as social interaction, technological advancement, and cultural exchange. The article also discusses the role of language in shaping individual and collective identities, particularly in multilingual societies where language choice often mirrors social hierarchies and power dynamics. Through this comprehensive analysis, the article underscores the importance of preserving linguistic diversity as a means of maintaining cultural heritage and promoting social cohesion in an increasingly globalized world.

description: La présente séquence didactique porte sur la Révolution française, en particulier sur la chute de l’Ancien Régime en 1789, la Politique de la Terreur menée par le Comité de salut public entre 1793 et 1795 et Napoléon Ier et l’Empire. L’activité a été créée dans le but de tester la plateforme Wikimini avec des élèves afin d’y publier un article encyclopédique. L’activité a été réalisée en suivant un dispositif d’enseignement bien précis : production initiale, identification des difficultés, développement de modules d’apprentissage et production finale. Elle s’est déroulée sur une quinzaine de périodes. La question de recherche à l’origine de ce travail peut être formulée ainsi : l’utilisation d’une plateforme en ligne favorise-t-elle l’écriture de l’histoire dans un cadre scolaire et permet-elle de faire émerger une réflexion critique sur l’utilisation des sources auprès des élèves ? De plus, le modèle collaboratif de Wikimini permet-il d’aborder la dimension collaborative et la controverse en histoire, en le confrontant au discours autoréférent du manuel scolaire ? Réalisée dans le but d’être exploitable par des enseignants, cette séquence didactique s’ouvre sur une réflexion théorique sur la démarche historique, puis se poursuit par le déroulement détaillé des modules d’apprentissage testés avec nos élèves. Une présentation des résultats conclut ce travail avec une typologie des erreurs et des pistes de remédiation possibles. L’écriture de l’histoire ne doit pas être une pratique isolée. Envisagée en situation, elle doit être enseignée comme un genre discursif en soi, et être intégrée le plus tôt possible à l’enseignement de l’histoire.

description: A new class of critical points, termed as perpetual points, where acceleration becomes zero but the velocity remains non-zero, are observed in dynamical systems. The velocity at these points is either maximum or minimum or of inflection behavior.These points also show the bifurcation behavior as parameters of the system vary. These perpetual points are useful for locating the hidden oscillating attractors as well as co-existing attractors. Results show that these points are important for better understanding of transient dynamics in the phase space. The existence of these points confirms whether a system is dissipative or not. Various examples are presented, and results are discussed analytically as well as numerically.

description: Durant notre formation à la HEP, nous nous sommes questionnées sur le déroulement de la rentrée scolaire. Afin de mieux comprendre les enjeux et les pratiques mises en place pendant cette période, nous avons axé notre recherche sur l’entrée dans la scolarité des élèves de première enfantine (1H). Nous avons faire l’hypothèse que les enseignant-e-s mettent en place des pratiques (rituels/routines, accueil des élèves et des parents, activités de présentation, règles de classe, découverte de l’établissement) lors de la rentrée scolaire afin de socialiser les élèves à la forme scolaire. En effet, la socialisation fait partie des apprentissages fondamentaux du cycle 1 selon le Plan d’études romand (PER, 2010). Cet apprentissage initie les élèves à « vivre ensemble » et à « apprendre ensemble ». Lors de cette recherche, nous avons observé deux classes durant les deux premières semaines de la rentrée scolaire. Par la suite, nous avons mené des entretiens individuels avec les élèves de 1H, puis un autre avec l’enseignante afin de mettre en évidence le vécu et les pratiques dans chaque classe. Pour finir, nous avons comparé les résultats des deux classes interrogées. Ceux-ci nous indiquent, entre autres, que la qualité de l’accueil des élèves lors de la rentrée scolaire leur assure un sentiment d’appartenance au sein de la classe. Les enseignantes interrogées expliquent aussi qu’il est important de rencontrer les parents afin de créer des liens pour le bien de l’enfant. Quant aux élèves, une majorité affirme avoir apprécié la présence de leurs parents lors de leur première journée en classe. Cependant, ils n’ont pas tous su en expliquer la raison. Notre étude a la particularité de prendre en compte l’avis de jeunes élèves qui sont souvent peu sollicités lors des différentes recherches dans l’enseignement. Cela permet d’avoir l’opinion des principaux acteurs concernés. Ce mémoire n’est pas un guide référentiel des pratiques à utiliser dans sa classe mais permet plutôt de décrire certaines pratiques mises en place lors de l’entrée dans la scolarité et leurs liens avec la visée de socialisation scolaire

description: Aims. We tested the new atomic model using atmospheric models of stars of different spectral types: the Sun (dG2), HD22049 (dK2, Epsilon Eridani), GJ 832 (dM2), and GJ 581 (dM3). Methods. We used new Breit-Pauli distorted-wave (DW) multiconfiguration calculations, which proved to be relevant for many transitions in the mid-infrared (MIR) range. The new atomic model of Mg I includes the following: i) recomputed ECS data through the DW method, including the superlevels. ii) For the nonlocal thermodynamic equilibrium (NLTE) population calculations, 5676 theoretical transitions were added (3001 term-to-term). iii) All of these improvements were studied in the Sun and the stars listed above. Results. The Mg distribution between ionization states for stars with different effective temperatures was compared. For the Sun and Epsilon Eridani, Mg II predominates with more than 95 %, while for GJ 832 and GJ 581, Mg I represents more than 72 % of the population. Moreover, in the latter stars, the amount of Mg forming molecules in their atmosphere is at least two orders of magnitude higher. Regarding the NLTE population, a noticeable lower variability in the departure coefficients was found, indicating a better population coupling for the new model. Comparing the synthetic spectrum calculated with the older and new Mg I atomic model, these results show minimal differences in the visible range but they are stronger in the IR for all of the stars. This aspect should be considered when using lines from this region as indicators. Nevertheless, some changes in the spectral type were found, also emphasizing the need to test the atomic models in different atmospheric conditions. The most noticeable changes occurred in the FUV and NUV, obtaining a higher flux for the new atomic model regardless of the spectral type.
External Photoevaporation of the Solar Nebula: Jupiter's Noble Gas Enrichments

description: We present a model explaining elemental enrichments in Jupiter's atmosphere, particularly the noble gases Ar, Kr, and Xe. While He, Ne and O are depleted, seven other elements show similar enrichments ($\sim$3 times solar, relative to H). Being volatile, Ar is difficult to fractionate from ${\rm H}_{2}$. We argue that external photoevaporation by far ultraviolet (FUV) radiation from nearby massive stars removed ${\rm H}_{2}$, He, and Ne from the solar nebula, but Ar and other species were retained because photoevaporation occurred at large heliocentric distances where temperatures were cold enough ($\lt 30$ K) to trap them in amorphous water ice. As the solar nebula lost H it became relatively and uniformly enriched in other species. Our model improves on the similar model of Guillot \& Hueso (2006). We recognize that cold temperatures alone do not trap volatiles; continuous water vapor production also is necessary. We demonstrate that FUV fluxes that photoevaporated the disk generated sufficient water vapor, in regions $\lt 30$ K, to trap gas-phase species in amorphous water ice, in solar proportions. We find more efficient chemical fractionation in the outer disk: whereas the model of Guillot \& Hueso (2006) predicts a factor of 3 enrichment when only $< 2\%$ of the disk mass remains, we find the same enrichments when 30\% of the disk mass remains. Finally, we predict the presence of $\sim 0.1 \, M_{\oplus}$ of water vapor in the outer solar nebula and in protoplanetary disks in H II regions.
