We explore the possibility that the observed population of Galactic hypervelocity stars
(HVSs) originate as runaway stars from the Large Magellanic Cloud (LMC). Pairing a binary …

We have investigated the origin of a sub-class of carbon-polluted white dwarfs (DQ)
originally identified as the “hot DQ” white dwarfs. These objects are relatively hot (K), have …

Subdwarf B stars are core-helium-burning stars located on the extreme horizontal branch
(EHB). Extensive mass loss on the red giant branch is necessary to form them. It has been …

Hot subdwarfs (sdO/B) are the stripped helium cores of red giants formed via binary
interactions. Close hot subdwarf binaries with massive white dwarf companions have been …

Some surviving companions of Type Ia supernovae (SNe Ia) from the white dwarf+ main-
sequence (WD+ MS) channel may evolve to hot subdwarfs. In this paper, we perform stellar …

Hot subdwarf stars of spectral types O and B represent a poorly understood phase in the
evolution of low-mass stars, in particular of close compact binaries. A variety of phenomena …

Hydrogen-deficient stars include the cool R CrB variable (RCBs) and hydrogen-deficient
carbon (HdCs) giants through extreme helium stars (EHes) to the very hot helium-rich …

Helium-burning hot subdwarf stars of spectral types O and B (sdO/B) are thought to be
produced through various types of binary interactions. The helium-rich hot subdwarf star EC …

We report on the detection of pulsations of three pulsating subdwarf B stars observed by the
Transiting Exoplanet Survey Satellite (TESS) satellite and our results of mode identification …
