description: The identification of new white dwarfs (WDs) polluted with heavy elements is important since they provide a valuable tool for inferring chemical properties of putative planetary systems accreting material on their surfaces. The Gaia space mission has provided us with an unprecedented amount of astrometric, photometric, and low resolution (XP) spectroscopic data for millions of newly discovered stellar sources, among them thousands of WDs. In order to find WDs among this data and to identify which ones have metals in their atmospheres, we propose a methodology based on an unsupervised artificial intelligence technique called Self-Organizing Maps (SOM). In our approach a nonlinear high-dimensional dataset is projected on a 2D grid map where similar elements fall into the same neuron.
 By applying this method, we obtained a clean sample of 66,337 WDs. We performed an automatic spectral classification analysis to them, obtaining 143 bona fide polluted WD candidates not previously classified in the literature. The majority of them are cool WDs and we identify in their XP spectra several metallic lines such as Ca, Mg, Na, Li, and K. The fact that we obtain similar precision metrics than those achieved with recent supervised techniques highlights the power of our unsupervised approach to mine the Gaia archives for hidden treasures to follow-up spectroscopically with higher resolution.

description: The observed dust rings and gaps in protoplanetary disks could be imprints of forming planets. Even low-mass planets in the one-to-ten Earth-mass regime, that do not yet carve deep gas gaps, can generate such dust rings and gaps by driving a radially-outwards gas flow, as shown in previous work. However, understanding the creation and evolution of these dust structures is challenging due to dust drift and diffusion, requiring an approach beyond previous steady state models. Here we investigate the time evolution of the dust surface density influenced by the planet-induced gas flow, based on post-processing three-dimensional hydrodynamical simulations. We find that planets larger than a dimensionless thermal mass of $m=0.05$, corresponding to 0.3 Earth mass at 1 au or 1.7 Earth masses at 10 au, generate dust rings and gaps, provided that solids have small Stokes numbers} (${\rm St}\lesssim10^{-2}$) and that the disk midplane is weakly turbulent ($α_{\rm diff}\lesssim10^{-4}$). As dust particles pile up outside the orbit of the planet, the interior gap expands with time, when the advective flux dominates over diffusion. Dust gap depths range from a factor a few, to several orders of magnitude, depending on planet mass and the level of midplane particle diffusion. We construct a semi-analytic model describing the width of the dust ring and gap, and then compare it with the observational data. We find that up to 65\% of the observed wide-orbit gaps could be explained as resulting from the presence of a low-mass planet, assuming $α_{\rm diff}=10^{-5}$ and ${\rm St}=10^{-3}$. However, it is more challenging to explain the observed wide rings, which in our model would require the presence of a population of small particles (${\rm St=10^{-4}}$). Further work is needed to explore the role of pebble fragmentation, planet migration, and the effect of multiple planets.

Psychological Abuse and Mental Health of  Transgenders: A Review

Subjects: subject: Transgender Persons/psychology
subject: Transgenders

description:  

The socioeconomic position of transgender individuals, including their employment and

education, plays a crucial role in their mental health outcomes. Transgender individuals

engaged in underground labour markets, such as sex work, often face a higher risk of

depression due to the associated risks and abuse within such occupations. Evidence suggests

that self-affirmation and gender-affirming interventions like hormone therapy and sex-change

surgery can potentially alleviate symptoms of depression and improve mental well-being

among transgender individuals. Family acceptance and support are also pivotal factors in the

mental health of transgender individuals, yet many parents struggle to accept their children's

gender identity, resulting in rejection and abuse. Family rejection has been found to predict

self-harm and suicide attempts among transgender and gender-nonconforming individuals,

highlighting the critical need for familial support. Furthermore, studies have consistently

shown that sexual minorities, including gay, lesbian, and bisexual individuals, are at a higher

risk of mental health issues than their heterosexual counterparts. Discrimination, prejudice,

and violence based on sexual orientation contribute to lower self-worth, increased suicide

risk, and mental health problems among sexual minorities, particularly during adolescence.

description: The Arches cluster, one of the most massive clusters in the Milky Way, is located about 30 pc in projection from the central massive black hole. With its high mass, young age, and location in the Galaxy's most extreme star forming environment, the Arches is an extraordinary laboratory to study massive stars and clusters. Our objective is to improve our knowledge of the properties of massive stars and the Arches cluster through high angular resolution radio continuum studies. We observed the Arches cluster with the Karl G. Jansky Very Large Array in the C- and X-bands throughout 2016, 2018, and 2022. We used the A-configuration to achieve the highest possible angular resolution and cross-matched the detected point sources with stars detected in the infrared, using proper motion catalogues to ensure cluster membership. We report the most extensive radio point source catalogue of the cluster to date, with a total of 25 radio detections. We also created the deepest radio images of the cluster so far. Most of our stellar radio sources (12/18) show a positive spectral index, indicating that the dominant emission process is free-free thermal radiation, which probably originates from stellar winds. We found that radio variability is more frequent than what was inferred from previous observations, affecting up to 60% of the sources associated with bright stellar counterparts. We propose four of our detections (F6, F18, F19 and F26) as primary candidates for colliding-wind binaries based on their consistent flat-to-negative spectral index. We classify F7, F9, F12, F14, and F55 as secondary colliding wind binary candidates based on their high flux and/or spectral index variability, and X-ray counterparts. Thus, we infer a 61% multiplicity fraction for the Arches cluster radio-stars when combining our findings with recent infrared radial velocity studies.

description: The composition of rocky planets is strongly driven by the primordial materials in the protoplanetary disk, which can be inferred from the abundances of the host star. Understanding this compositional link is crucial for characterizing exoplanets. We aim to investigate the relationship between the compositions of low-mass planets and their host stars. We determined the primordial compositions of host stars using high-precision present-day stellar abundances and stellar evolutionary models. These primordial abundances were then input into a stoichiometric model to estimate the composition of planet-building blocks. Additionally, we employed a three-component planetary interior model (core, mantle, water in different phases) to estimate planetary compositions based only on their radius and mass. We found that although stellar abundances vary over time, relevant abundance ratios like Fe/Mg remain relatively constant during the main sequence evolution for low temperature stars. A strong correlation is found between the iron-to-silicate mass fraction of protoplanetary disks and planets, while no significant correlation was observed for water mass fractions. The Fe/Mg ratio varies significantly between planets and their stars, indicating substantial disk-driven compositional diversity, and this ratio also correlates with planetary radius. While stellar abundances, as a proxy of the composition of protoplanetary disk, provide a baseline for planetary composition, significant deviations arise due to complex disk processes, challenging the assumption of a direct, one-to-one elemental relationship between stars and their planets.

description: At the sub-stellar boundary, signatures of magnetic fields begin to manifest at radio wavelengths, analogous to the auroral emission of the magnetised solar system planets. This emission provides a singular avenue for measuring magnetic fields at planetary scales in extrasolar systems. So far, exoplanets have eluded detection at radio wavelengths. However, ultracool dwarfs (UCDs), their higher mass counterparts, have been detected for over two decades in the radio. Given their similar characteristics to massive exoplanets, UCDs are ideal targets to bridge our understanding of magnetic field generation from stars to planets. In this work, we develop a new tomographic technique for inverting both the viewing angle and large-scale magnetic field structure of UCDs from observations of coherent radio bursts. We apply our methodology to the nearby T8 dwarf WISE J062309.94-045624.6 (J0623) which was recently detected at radio wavelengths, and show that it is likely viewed pole-on. We also find that J0623's rotation and magnetic axes are misaligned significantly, reminiscent of Uranus and Neptune, and show that it may be undergoing a magnetic cycle with a period exceeding 6 months in duration. These findings demonstrate that our method is a robust new tool for studying magnetic fields on planetary-mass objects. With the advent of next-generation low-frequency radio facilities, the methods presented here could facilitate the characterisation of exoplanetary magnetospheres for the first time.

description: We provide an updated inference of the proper motion of M31 using the Gaia DR3 proper motions of bright stars from the disc of M31. By refining the motion of the quasar reference frame, and statistically accounting for the variations in the inferred proper motions obtained across different regions of M31, we demonstrate that these inconsistencies most likely arise from systematic uncertainties. Our updated favoured values for the proper motion of M31 are 46.9$\pm$11.7(stat)$\pm$50.6(sys)$μ$as yr$^{-1}$ along the right ascension direction, and -29.1$\pm$9.4(stat)$\pm$35.6(sys)$μ$as yr$^{-1}$ along the declination direction, the systematics being determined at a 90% confidence level (the values for M33 are given in the paper). This clearly highlights that the systematics are the dominant source of uncertainty, their magnitudes being comparable to the proper motion of M31 itself. The analysis conducted using Gaia DR2 instead of DR3 revealed that a net reduction in these systematic uncertainties occurred between the two data releases. If similar progress is made with the upcoming DR4, the future Gaia-based estimates could match the level of uncertainties of HST, and could be used to refine the dynamics and history of M31 and M33.

The origin and evolution of the [CII] deficit in HII regions and star-forming molecular clouds

description: We analyse synthetic maps of the [CII] 158 $μ$m line and FIR continuum of simulated molecular clouds (MCs) within the SILCC-Zoom project to study the origin of the [CII] deficit, i.e., the drop in the [CII]/FIR intensity ratio. All simulations include stellar radiative feedback and account for further ionisation of C$^+$ into C$^{2+}$ inside HII regions. For individual HII regions, $I_\mathrm{FIR}$ is initially high in the vicinity of young stars, and then moderately decreases as the gas is compressed into shells. In contrast, $I_\mathrm{CII}$ drops strongly over time, to which the second ionisation of C$^+$ into C$^{2+}$ contributes. This leads to a large drop in $I_\mathrm{[CII]}/I_\mathrm{FIR}$ inside HII regions, decreasing from 10$^{-3}$-10$^{-2}$ at scales above 10 pc to 10$^{-6}$-10$^{-4}$ at scales below 2pc. However, projection effects can affect the radial profile of $I_\mathrm{[CII]}$ and $I_\mathrm{FIR}$ and create apparent HII regions without any stars. On MC scales, $L_\mathrm{[CII]}/L_\mathrm{FIR}$ decreases from values $\gtrsim$10$^{-2}$ in MCs without star formation to values around $\sim10^{-3}$ in MCs with star formation. We attribute this and the origin of the [CII] deficit to two main contributors: (i) the saturation of the [CII] line and (ii) the conversion of C$^+$ into C$^{2+}$ by stellar radiation. The drop in $L_\mathrm{[CII]}/L_\mathrm{FIR}$ can be divided into two phases: (i) early on, the saturation of [CII] and the further ionisation of C$^+$ limit the increase in $L_\mathrm{[CII]}$, while $L_\mathrm{FIR}$ increases rapidly, leading to the initial decline of $L_\mathrm{[CII]}/L_\mathrm{FIR}$. (ii) In more evolved HII regions, $L_\mathrm{CII}$ stagnates and even partially drops due to the aforementioned reasons. $L_\mathrm{FIR}$ stagnates as the gas gets pushed into the cooler shells keeping $L_\mathrm{[CII]}/L_\mathrm{FIR}$ at low values of $\sim10^{-3}$.

Ruhland (1903) described Paepalanthus speciosus var. glabrus based on eight collections. Careful fieldwork and herbarium analysis lead to the conclusion that these specimens correspond to several formerly described species. The collection Glaziou 19977 best fits the original description, and is thus designated here as the lectotype. Ruhland (1903) also briefly described Paepalanthus speciosus var. angustifolius based on two collections. The specimen Mathieu Libon 534 in C fits the original description most adequately and is therefore designated here as the lectotype.

description: During the solar cycle, the Sun's magnetic field polarity reverses due to the emergence, cancellation, and advection of magnetic flux towards the rotational poles. Flux emergence events occasionally cluster together, although it is unclear if this is due to the underlying solar dynamo or simply by chance. Regardless of the cause, we aim to characterise how the reversal of the Sun's magnetic field and the structure of the solar corona are influenced by nested flux emergence. From the spherical harmonic decomposition of the Sun's photospheric magnetic field, we identify times when the reversal of the dipole component stalls for several solar rotations. Using observations from sunspot cycle 23 to present, we locate the nested active regions responsible for each stalling and explore their impact on the coronal magnetic field using potential field source surface extrapolations. Nested flux emergence has a more significant impact on the topology of the coronal magnetic field than isolated emergences as it produces a coherent (low spherical harmonic order) contribution to the photospheric magnetic field. The heliospheric current sheet (HCS), that separates oppositely directed coronal magnetic field, can become anchored above these regions due to the formation of strong opposing magnetic fluxes. Further flux emergence, cancellation, differential rotation, and diffusion, then effectively advects the HCS and shifts the dipole axis. Nested flux emergence can restrict the evolution of the HCS and impede the reversal of the coronal magnetic field. The sources of the solar wind can be more consistently identified around nested active regions as the magnetic field topology remains self-similar for multiple solar rotations. This highlights the importance of identifying nested active regions to guide the remote-sensing observations of modern heliophysics missions.

description: Detached eclipsing binaries (DEBs) allow for the possibility of precise characterization of its stellar components. They offer a unique opportunity to derive their physical parameters in a near-model-independent way for a number of systems consisting of late-type giant stars. Here we aim to expand the sample of low-metallicity late-type giant stars with precise parameters determined. We aim to determine the fundamental parameters like the mass, radius, or effective temperature for three long-period late-type eclipsing binaries from the Large Magellanic Cloud: OGLE-LMC-ECL-25304, OGLE-LMC-ECL-28283, and OGLE-IV LMC554.19.81. Subsequently we aim to determine the evolutionary stages of the systems. We fit the light curves from the OGLE project and radial velocity curves from high resolution spectrographs using the Wilson-Devinney code. The spectral analysis was performed with the GSSP code and resulted in the determination of atmospheric parameters such as effective temperatures and metallicities. We used isochrones provided by the MIST models based on the MESA code to derive evolutionary status of the stars. We present the first analysis of three DEBs composed of similar He-burning late-type stars passing through the blue loop. Estimated masses for OGLE-LMC-ECL-29293 (G4III + G4III) are $M_1=2.898\pm0.031$ and $M_2=3.153\pm0.038$ $M_\odot$, stellar radii are $R_1=19.43\pm0.31$ and $R_2=19.30\pm0.31$ $R_\odot$. OGLE-LMC-ECL-25304 (G4III + G5III) has stellar masses of $M_1=3.267\pm0.028$ and $M_2=3.229\pm0.029$ $M_\odot$, radii of $R_1=23.62\pm0.42$ and $R_2=25.10\pm0.43$ $R_\odot$. OGLE-IV LMC554.19.81 (G2III + G2III) have masses of $M_1=3.165\pm0.020$ and $M_2=3.184\pm0.020$ $M_\odot$, radii of $R_1=18.86\pm0.26$ and $R_2=19.64\pm0.26$ $R_\odot$. All masses were determined with a precision better than 2\% and radii better than 1.5\%. The ages of the stars are in the range of 270-341 Myr.

Notes on identification of larva. Pschorn-Walcher & Altenhofer (2006) first mentioned Knautia arvensis as the food plant of this species. The larva of M. erythrocnema, as described above, is very similar to that of M. recognata, but differs in its ecology. Unlike M. recognata this is a xerophilous species associated with xeric grasslands in lower altitudes.
Bionomics. Habitat: dry grasslands and xeric fringes in lowland and foothill zones. Univoltine. Flight period from mid May to the beginning of July; larval period from mid June to the end of July. Host plant: Knautia arvensis. The larvae rest on the underside of leaves. The infested plants are traced by the large holes on the leaves. Larval development is relatively fast, lasting about four to five weeks; the eonymph rests for a longer time (up to six weeks) coiled on the underside of the leaves of various surrounding vegetation before burrowing into the soil for hibernation diapause.

description: We investigate the effect of data-driving on flux rope eruptivity in magnetic field simulations by analysing fully data-driven modelling results of active region (AR) 12473 and AR11176, as well as preforming relaxation runs for AR12473 (found to be eruptive). Here, the driving is switched off systematically at different time steps. We analyse the behaviour of fundamental quantities, essential for understanding the eruptivity of magnetic flux ropes (MFRs). The data-driven simulations are carried out with the time-dependent magnetofrictional model (TMFM) for AR12473 and AR11176. For the relaxation runs, we employ the magnetofrictional method (MFM) and a zero-beta magnetohydrodynamic (MHD) model to investigate how significant the differences between the two relaxation procedures are when started from the same initial conditions. To determine the eruptivity of the MFRs, we calculate characteristic geometric properties, such as the cross-section, MFR height along with stability parameters, such as MFR twist and the decay index. For eruptive cases, we investigate the effect of sustained driving beyond the point of eruptivity on the MFR properties. We find that the fully-driven AR12473 MFR is eruptive while the AR11176 MFR is not. For the relaxation runs, we find that the MFM MFRs are eruptive when the driving is stopped around the flare time or later, while the MHD MFRs show eruptive behaviour even if the driving is switched off one and a half days before the flare occurs. We find that characteristic MFR properties can vary greatly even for the eruptive cases of different relaxation simulations. The results suggest that data driving can significantly influence the evolution of the eruption, with differences appearing even when the relaxation time is set to later stages of the simulation when the MFRs have already entered an eruptive phase.
