Winds in Star Clusters Drive Kolmogorov Turbulence
Authors: Gallegos-Garcia Monica , Burkhart Blakesley , Rosen Anna L. , Naiman Jill P. , Ramirez-Ruiz Enrico 
Published: August 2020

Abstract
Intermediate and massive stars drive fast and powerful isotropic winds that interact with the winds of nearby stars in star clusters and the surrounding interstellar medium (ISM). Wind–ISM collisions generate astrospheres around these stars that contain hot T ∼ 107 K gas that adiabatically expands. As individual bubbles expand and collide they become unstable, potentially driving turbulence in star clusters. In this Letter we use hydrodynamic simulations to model a densely populated young star cluster within a homogeneous cloud to study stellar wind collisions with the surrounding ISM. We model a mass-segregated cluster of 20 B-type young main-sequence stars with masses ranging from 3 to 17 M
⊙. We evolve the winds for ∼11 kyr and show that wind–ISM collisions and overlapping wind-blown bubbles around B-stars mix the hot gas and ISM material, generating Kolmogorov-like turbulence on small scales early in its evolution. We discuss how turbulence driven by stellar winds may impact the subsequent generation of star formation in the cluster.
Color Gradients along the Quiescent Galaxy Sequence: Clues to Quenching and Structural Growth
Authors: Suess Katherine A. , Kriek Mariska , Price Sedona H. , Barro Guillermo 
Published: August 2020

Abstract
This Letter examines how the sizes, structures, and color gradients of galaxies change along the quiescent sequence. Our sample consists of ∼400 quiescent galaxies at 1.0 ≤ z ≤ 2.5 and

in three CANDELS fields. We exploit deep multi-band Hubble Space Telescope imaging to derive accurate mass profiles and color gradients, then use an empirical calibration from rest-frame UVJ colors to estimate galaxy ages. We find that—contrary to previous results—the youngest quiescent galaxies are not significantly smaller than older quiescent galaxies at fixed stellar mass. These “post-starburst” galaxies only appear smaller in half-light radii because they have systematically flatter color gradients. The strength of color gradients in quiescent galaxies is a clear function of age, with older galaxies exhibiting stronger negative color gradients (i.e., redder centers). Furthermore, we find that the central mass surface density Σ1 is independent of age at fixed stellar mass, and only weakly depends on redshift. This finding implies that the central mass profiles of quiescent galaxies do not significantly change with age; however, we find that older quiescent galaxies have additional mass at large radii. Our results support the idea that building a massive core is a necessary requirement for quenching beyond z = 1, and indicate that post-starburst galaxies are the result of a rapid quenching process that requires structural change. Furthermore, our observed color gradient and mass profile evolution supports a scenario where quiescent galaxies grow inside-out via minor mergers.

Abstract
We obtained high-resolution, diffraction limited imaging of the candidate binary RR Lyrae UV Oct using Gemini-South/Zorro. We detect no companions between 0.″1 and 1.″2, with a contrast of Δm ∼ 5 mag, placing a mass constraint for any possible main sequence companion of m < 0.67M

Abstract
Space-weathering as well as shock effects can darken meteorite and asteroid reflectance spectra. We present a detailed comparative study on shock-darkening and space-weathering using different lithologies of the Chelyabinsk LL5 chondrite. Compared to space-weathering, the shock processes do not cause significant spectral slope changes and are more efficient in attenuating the orthopyroxene 2 μm absorption band. This results in a distinct shock vector in the reflectance spectra principal component analysis, moving the shocked silicate-rich Chelyabinsk spectra from the S-complex space into the C/X complex. In contrast to this, the space-weathering vector stays within the S complex, moving from Q type to S type. Moreover, the 2 μm to 1 μm band depth ratio (BDR) as well as the 2 μm to 1 μm band area ratio (BAR) are not appreciably affected by shock-darkening or shock melting. Space-weathering, however, causes significant shifts in both BDR and BAR toward higher values. Application of the BDR method to the three distinct areas on the asteroid Itokawa reveals that Itokawa is rather uniformly space-weathered and not influenced by regolith roughness or relative albedo changes.
A Volatile-poor Formation of LHS 3844b Based on Its Lack of Significant Atmosphere

Published: August 2020

Abstract
Exoplanet discoveries have reached into the realm of terrestrial planets that are becoming the subject of atmospheric studies. One such discovery is LHS 3844b, a 1.3 Earth radius planet in a 0.46 day orbit around an M4.5-5 dwarf star. Follow-up observations indicate that the planet is largely devoid of substantial atmosphere. This lack of significant atmosphere places astrophysical and geophysical constraints on LHS 3844b, primarily the degree of volatile outgassing and the rate of atmosphere erosion. We estimate the age of the host star as 7.8 ± 1.6 Gyr and find evidence of an active past comparable to that of Proxima Centauri. We use geodynamical models of volcanic outgassing and atmospheric erosion to show that the apparent lack of atmosphere is consistent with a volatile-poor mantle for LHS 3844b. We show the core is unlikely to host enough C to produce a sufficiently volatile-poor mantle, unless the bulk planet is volatile-poor relative to Earth. While we cannot rule out a giant impact stripping LHS 3844b’s atmosphere, we show that this mechanism would require significant mantle stripping, potentially leaving LHS 3844b as an Fe-rich “super-Mercury.” Atmospheric erosion by smaller impacts is possible, but only if the planet has already begun degassing and is bombarded by 103 impactors of radius 500–1000 km traveling at escape velocity. We discuss formation and migration scenarios that could account for a volatile-poor origin, including the potential for an unobserved massive companion planet. A relatively volatile-poor composition of LHS 3844b suggests that the planet formed interior to the system snow line.
Une norme disputée : l’indemnité parlementaire en France (1789-1914)
Authors: Monier Frédéric , Portalez Christophe 
Published: August 2020

La création d’une indemnité législative intervient en France à l’été 1789. Imbriquée dans les projets révolutionnaires, elle suscite la gêne de nombreux députés, et attise des débats récurrents. Remise en cause par le premier Empire, abrogée par la monarchie censitaire, réintroduite en 1848, cette norme nouvelle est paradoxalement confortée par le Second Empire. Le traitement des élus ne va pas de soi, y compris après 1870 : les refus persistants de dédommager les mandats locaux et l’indignation suscitée par l’augmentation de l’indemnité parlementaire fin 1906 montrent que, pour une partie de la société française, l’idée que la politique soit un métier rémunéré est perçue comme une corruption, encore à la veille de la Grande Guerre.
Éduquer pour la République, Jeanne Desparmet-Ruello, une intellectuelle au temps de Jaurès
Authors: Fabre Mélanie 
Published: August 2020

Méconnue de l’historiographie, Jeanne Desparmet-Ruello est une intellectuelle qui, dans le sillage de Jaurès, considère l’école laïque comme une priorité pour la Troisième République. Dreyfusarde, elle est la fondatrice et présidente de l’Université populaire lyonnaise qu’elle fait vivre entre 1899 et 1905. Femme de science aux convictions rationalistes, elle milite pour appliquer partout la laïcité scolaire dans un contexte de concurrence avec l’école catholique. Libre penseuse, elle se prête à des manifestations qui lui attirent des attaques dans la presse lyonnaise et des conflits avec son administration. Directrice du lycée de jeunes filles de Lyon, Jeanne Desparmet-Ruello éprouve les limites de sa liberté d’action et de parole, dans un contexte où les femmes professeurs, pour faire se faire accepter socialement, doivent se conformer à un idéal de discrétion. Par ailleurs, les engagements de Jeanne Desparmet-Ruello ne sont pas toujours jugés compatibles avec son statut de fonctionnaire, qui impose devoir de réserve et de neutralité. C’est donc sous un pseudonyme qu’on la retrouve dans les colonnes de la Fronde , quotidien qui associe la lutte féministe au combat pour les droits de l’homme dans le contexte de l’Affaire. Grande actrice de l’éducation populaire, Jeanne Desparmet-Ruello se revendique socialiste, mais adopte des positions plutôt hétérodoxes. En quoi consiste donc son socialisme ? Peut-il être qualifié de jaurésien ? Pourquoi est-il indissociable de son engagement féministe, dreyfusard et libre penseur ?
L’Internationale et la grève du bronze de 1867 : une renaissance de la Première Internationale
Authors: Grimaud Julien 
Published: August 2020

Fortement enraciné et unanimement professé, le credo proudhonien des sections françaises de l’Internationale à ses débuts s’accompagne, au cours de l’intervalle des années 1867-1869, d’une pratique qui en contredit cependant fondamentalement le paradigme : la grève ! Cette contradiction, que le seul prisme idéologique de l’historiographie consacrée laissa longtemps impensée, se révèle notamment à l’occasion de la grande grève des ouvriers bronziers de mars-avril 1867 à Paris. Une grève dont la démonstration de force de l’AIT (Association interna- tionale des travailleurs) et les décantations politique qu’elle occasionne sur le long terme, offrent matière à l’analyse d’une étiologie sociale de la mutation du petit cercle d’étude proudhonien en un véritable outil de résistance ouvrière.
Un portraitiste de Jaurès, Éloy-Vincent
Authors: Huard Raymond 
Published: August 2020

Parmi les très nombreux auteurs de représentations de Jaurès, la place d’Albert Éloy-Vincent n’est sans doute pas la plus importante, mais elle est néanmoins assez originale pour qu’on s’intéresse de plus près à son auteur. Si son tableau qui contient six dessins de Jaurès parlant à la Chambre en 1910 intitulé « Croquis pour servir à l’histoire de l’éloquence », conservé au Centre national et musée Jaurès de Castres, est bien connu et a été reproduit de nombreuses fois à l’appui d’un article ou d’un livre sur Jaurès, son auteur en revanche est à peu près ignoré. Qui était-il ? Comment s’est-il intéressé à Jaurès ? A-t-il donné d’autres représentations du leader socialiste ? Quelle place exacte occupe Jaurès dans ce qu’on peut appeler son panthéon républicain ? C’est à ces questions que cet article cherche à répondre.

The Sketch of Age in Shakespeare’s Henry IV (Parts 1 and 2)
Authors: Sarkar Dipak Kumar 
Published: August 2020

As there is birth, everything including human being is certain of the journey of being aged but the society and its various institutions became dogmatic at the time of approaching an aged man focusing on their norms and culture. On the other hand, there is no universal definition or margin of calling a person aged. Despite the people in the society, however knowledgeable and gifted they are, keep on pursuing the social norm and cannot think over it. Shakespeare is also one of them who consider the age as the society sees. But, being an undisputed and world class writer, this approach cannot be expected from Shakespeare. And so, this paper investigates Shakespeare’s attitude towards age and aged people in comparison to the young in the both parts of the drama, Henry IV. For this investigation, the text with all its annotations and critics’ comments are analysed minutely from a gerontological point of view. This study also examines the concept of aging in some other works of Shakespeare.
Nature as a Motif in Arabic Andalusian Poetry and English Romanticism
Authors: Aburqayeq Ghassan 
Published: August 2020

This paper examines some tenets in the Andalusian and Romantic poetry and shows how poets such as Ibrahim Ibn Khafāja (1058-1138) and William Wordsworth (1770 –1850) used nature as a motif in their poetry. Relying on a historical approach, this paper links smaller features such as themes and literary devices in the Andalusian and Romantic poetry with larger features, including genre, traditions, and cultural system. I argue that the emphasis on both the larger and smaller features of poetry creates what Franco Moretti calls “distant reading.” Comparing and contrasting Ibn Khafāja’s “the Mountain” and Wordsworth’s “the Daffodils,” for instance, introduces nature as a recurrent theme in both Andalusian and Romantic literary traditions, reinforcing Johann Wolfgang Goethe’s description of poetry as a common possession of humanity” (Goethe 229). In addition to that, comparing the images and themes in both the Andalusian and Romantic poetry not only shows internally linked meanings, but it creates what Cesar Domínguez, et al, call “a space for polyglottism, multidisciplinarity, scholarly collaboration” (75). Reading these works and movements closely and distantly serves as a cross-cultural dialogue between the Arabic and English poetic conventions. While Ibn Khafāja and Wordsworth lived in different places and times, wrote in different languages, and did not have the same socio-political circumstances, their poems show the richness and multiplicity of the historical experience of world literature.
Migration and Its Discontents: A Postcolonial Rendering of NoViolet Bulawayo’s We Need New Names
Authors: Babou Ngom Mamadou Abdou 
Published: August 2020

This research paper is my attempt, through a blow-by-blow analysis of a fictional work of a rising star in postcolonial writing, to grapple with the manifold discontents that attend the event of migration. Migration is an astoundingly painful experience to go through, whose multifaceted toll on the subject may be beyond repair. Using NoViolet Bulawayo’s We Need New names as a stepping-stone, I argue that migration, albeit a time-honoured phenomenon has picked up speed in the twentieth-century and continued into the twenty-first century with a most heavy human toll. The paper emphasizes that even though the act of migration is underpinned by a hope for betterment, it may turn out to be a damp squid. No end of landmines and hiccups dot the migratory journey. The long-suffering postcolonial subject, hallmarked by the stifling strictures of marginality owing to a long history of race-based oppression that stretches back to the gruesome eras of the trans-Atlantic slave trade and colonization, is on the receiving end of the horrors of migration. I tap into key terms in postcolonial theory cum sociology-informed perspectives to make a valid point about the dehumanizing fallout from the migratory experience.
