A Star's Death by a Thousand Cuts: The Runaway Periodic Eruptions of AT2023uqm
Yibo Wang, Tingui Wang, Shifeng Huang +37
Stars on bound orbits around a supermassive black hole may undergo repeated partial tidal disruption events (rpTDEs), producing periodic flares. While several candidates have been…
Fates of Rotating Supergiants from Stellar Mergers and the Landscape of Transients upon Core-collapse
Daichi Tsuna, Jim Fuller, Wenbin Lu
We present a grid of rotating supergiant models from post-main sequence binary merger products, constructed by the MESA stellar evolution code. We focus on the evolution of these s…
Accretion from a shock-inflated companion: double-peaked supernova lightcurve with periodic modulations
Wenbin Lu, Savannah Cary, Daichi Tsuna
We study the observational signatures from the interactions between a newly born neutron star and a companion star that is impacted by the supernova ejecta. We focus on the cases w…
Accretion from a Shock-Inflated Companion: Spinning Down Neutron Stars to Hour-Long Periods
Savannah Cary, Wenbin Lu, Calvin Leung +1
Recent observations have unveiled a population of pulsars with spin periods of a few minutes to hours that lie beyond the traditional ``death line.'' If they originate from neutron…
Review: Accretion Disk Evolution in Tidal Disruption Events
Wenbin Lu
This is a brief review of the recent progress in understanding the evolution of the accretion disks in tidal disruption events (TDEs). Special attention is paid to (1) thermal-visc…
Interaction of an outflow with surrounding gaseous clouds as the origin of the late-time radio flares in TDEs
Jialun Zhuang, Rong-Feng Shen, Guobin Mou +1
Close encounter between a star and a supermassive black hole (SMBH) results in the tidal disruption of the star, known as a tidal disruption event (TDE). Recently, a few TDEs, e.g.…
