Hydrodynamics of Collisions and Close Encounters between Stellar Black Holes and Main-sequence Stars
No full textRecent analyses have shown that close encounters between stars and stellar black holes occur frequently in dense star clusters. Depending upon the distance at closest approach, these interactions can lead to dissipating encounters such as tidal captures and disruptions, or direct physical collisions, all of which may be accompanied by bright electromagnetic transients. In this study, we perform a wide range of hydrodynamic simulations of close encounters between black holes and main-sequence stars that collectively cover the parameter space of interest, and we identify and classify the various possible outcomes. In the case of nearly head-on collisions, the star is completely disrupted with roughly half of the stellar material becoming bound to the black hole. For more distant encounters near the classical tidal-disruption radius, the star is only partially disrupted on the first pericenter passage. Depending upon the interaction details, the partially disrupted stellar remnant may be tidally captured by the black hole or become unbound (in some cases, receiving a sufficiently large impulsive kick from asymmetric mass loss to be ejected from its host cluster). In the former case, the star will undergo additional pericenter passages before ultimately being disrupted fully. Based on the properties of the material bound to the black hole at the end of our simulations (in particular, the total bound mass and angular momentum), we comment upon the expected accretion process and associated electromagnetic signatures that are likely to result.Published articl
Ecocriticism and the Body
No full text“Bodies tell stories.” So begins the fifth chapter of Salvage the Bones, Jesmyn Ward’s 2011 novel of Hurricane Katrina’s racialized landscapes. The story follows fifteen-year-old Esch Batiste, a Black teenager living in rural poverty with her family along the Mississippi Gulf Coast in the days leading up to the 2005 storm. Pregnant and caught between emerging desires as an adolescent woman and compounding responsibilities as an expectant mother, Esch utters these words as she rushes into the family’s bathroom, bursting to pee, and sees her older brother Skeetah softly touching wounds on his stomach. Esch alludes to the stories revealed by her own pregnant belly and those inscribed on her brother’s torso, which tell of the ravaging of his body in exchange for resources. Ward weaves these corporeal stories into a broader narrative of racialized embodiment, structural abandonment, and environmental vulnerability as they inextricably entangle in the southern United States.Published articl
O O “Livro do Êxodo” como chave de análise para o estudo da migração
No full textThis paper approaches “Exodus” like a source to analytical Keys for studies about migration, namely labor and the utopian dimension of the migrants. There is not archaeological nether documentary evidence to prove the movement of Hebrews where Israel is located today. The subject taken for historical analysis is the means of migration. It is a cultural strategy to Hebrews and Moses. In the context, the “Exodus” is thinking as a historical practice of migration, dilemmas experienced between exile and home. Thus, Moses is approached like a synthesis of the migrant.Este artigo aborda o “Livro do Êxodo” como fonte de duas chaves analíticas para o estudo da migração: o trabalho e a dimensão utópica do migrante. Não há provas arqueológicas nem documentais que endossem o deslocamento de hebreus para fora do Egito Antigo em direção à região onde hoje se localiza Israel. O que se toma como fonte para discussão histórica é a permanência da crença judaica e cristã atual no significado desse deslocamento, uma migração que é também um recurso e prática cultural. Nesse contexto, pensar o “Êxodo” como uma prática histórica de migração e, portanto, um retrato de dilemas vividos entre o exílio e o pertencimento, a figura de Moisés é abordada como uma síntese do migrante
A DRAMATURGIA COMO LUGAR DE MEMÓRIA EM VILLA, DE GUILLERMO CALDERÓN
Get PDFResumo: O que fazer com os espaços destinados a práticas de torturas e desaparecimentos durante os regimes de exceção? Esse é o mote central de Villa, dramaturgia de Guillermo Calderón, em que três mulheres discutem, na atualidade, sobre o que fazer com os escombros de um centro de detenção, tortura e assassinato durante o regime ditatorial de Augusto Pinochet, no Chile. No presente texto, analisamos como a peça chilena se estrutura como um lugar de memória, refletindo qual o papel da arte na preservação das lembranças dos traumas sociais, tendo como suporte os apontamentos de Pierre Nora, Maurice Halbwachs, Elizabeth Jelin, Ludmila da Silva Catela e Márcio Seligmann-Silva
