Quantifying the impact of relativistic precession on tidal disruption event light curves
Diego Calderón, Ondřej Pejcha, Brian D. Metzger +2
The tidal field of a black hole can turn a star into a gas stream whose orbit can precess, especially if the a black hole is rapidly spinning. In this work, we investigate the impa…
Two-Dimensional Radiation-Hydrodynamic Simulations of Luminous Red Novae
Anthony Kirilov, Diego Calderón, Ondřej Pejcha +1
Luminous Red Novae (LRNe) are transients associated with mass ejection during stellar mergers and common envelope evolution (CEE). LRNe have the potential to illuminate the poorly…
On the effects of radiation on mass transfer in binary stars
Jakub Cehula, Ondřej Pejcha
Mass transfer (MT) in binary systems is a common evolutionary process that can significantly affect the structure, evolution, and final fate of both stars. In modeling MT hydrodyna…
Journey to the center of the common envelope evolution. Inner dynamics of the post-dynamical inspiral
Damien Gagnier, Ondrej Pejcha
Three-dimensional hydrodynamical simulations of common envelope evolution are often terminated soon after the initial dynamical plunge of the companion transitions into a long-last…
Distinguishing between light curves of ellipsoidal variables with massive dark companions, contact binaries, and semidetached binaries using principal component analysis
Milan Pešta, Ondřej Pejcha
Photometric methods for identifying dark companion binaries - binary systems hosting quiescent black holes and neutron stars - operate by detecting ellipsoidal variations caused by…
Driving asymmetric red supergiants winds with binary interactions
Camille Landri, Ondřej Pejcha
Massive stars in the red supergiant (RSG) phase are known to undergo strong mass loss through winds and observations indicate that a substantial part of this mass loss could be dri…
