Tidal disruption of stellar binaries as a pathway to exotic transients
Mauricio González-Servín, Emilio Tejeda, Susana Lizano +2
Tidal disruption event (TDE) progenitors are commonly modelled as single stars on parabolic orbits around a supermassive black hole (SMBH), yet observations reveal a richer diversi…
A benchmark for binary star interaction with a supermassive black hole in general relativity
Megha Sharma, Alexander Heger, Daniel J. Price +4
Most galaxies have supermassive black holes (SMBH) at their centres, surrounded by stars with binary systems also present in this environment. We use two schemes - post-Newtonian (…
Accretion in Binary Systems with Slow Stellar Winds
Jesús A. Toalá, Emilio Tejeda, Raúl F. Maldonado +1
Wind accretion in binary systems is commonly described using the Bondi-Hoyle-Lyttleton (BHL) formalism. However, its standard implementation fails in the slow-wind regime, where th…
Relativistic tidal separation of binary stars by supermassive black holes
Luis A. Manzaneda, César O. Navarrete, Emilio Tejeda
A binary stellar system that ventures too close to a supermassive black hole can become tidally separated. In this article, we investigate the role of relativistic effects in these…
Bondi-Hoyle-Lyttleton Accretion in a Reactive Medium: Detonation Ignition and a Mechanism for Type Ia Supernovae
Heinrich Steigerwald, Emilio Tejeda
Detonation initiation in a reactive medium can be achieved by an externally created shock wave. Supersonic flow onto a gravitating center, known as Bondi-Hoyle-Lyttleton (BHL) accr…
Spherical accretion: Bondi, Michel and rotating black holes
Alejandro Aguayo-Ortiz, Emilio Tejeda, Olivier Sarbach +1
In this work we revisit the steady state, spherically symmetric gas accretion problem from the non-relativistic regime to the ultra-relativistic one. We first perform a detailed co…
