Spin evolution modeling for a newly-formed white dwarf resulting from binary white dwarf merger
Yanchang Cheng, Jumpei Takata
Merger of two white dwarfs (WDs) has been proposed to form an isolated WD having high magnetization and rapid rotation. We study the influence of the magnetohydrodynamic (MHD) wind…

Probing vector gravitational atoms with eccentric intermediate mass-ratio inspirals
Yan Cao, Ya-Ze Cheng, Gen-Liang Li +1
Ultralight bosons, proposed as candidates for dark matter (DM), are predicted by various new physics models. In the presence of bosons with suitable masses, superradiant (SR) insta…

Effects of black hole environments on extreme mass-ratio hyperbolic encounters
Ya-Ze Cheng, Yan Cao, Yong Tang
Extreme mass-ratio hyperbolic encounters (EMRHEs) around the supermassive black holes will be observable at the future gravitational-wave (GW) detectors in space, such as LISA and…
