Multi-mode delta Sct stars from the Zwicky Transient Facility Survey
Qi Jia, Xiaodian Chen, Shu Wang +3
We obtain the largest catalog of multi-mode Sct stars in the northern sky to date using the Zwicky Transient Facility (ZTF) Data Release 20 (DR20). The catalog includes 2254 ob…
An 18.9-minute Blue Large-Amplitude Pulsator Crossing the 'Hertzsprung Gap' of Hot Subdwarfs
Jie Lin, Chengyuan Wu, Xiaofeng Wang +28
Blue large-amplitude pulsators (BLAPs) represent a new and rare class of hot pulsating stars with unusually large amplitudes and short periods. Up to now, only 24 confirmed BLAPs h…
A Roche Lobe-filling hot Subdwarf and White Dwarf Binary: possible detection of an ejected common envelope
Jiangdan Li, Christopher A. Onken, Christian Wolf +12
Binaries consisting of a hot subdwarf star and an accreting white dwarf (WD) are sources of gravitational wave radiation at low frequencies and possible progenitors of type Ia supe…
Extremely low-mass white dwarf stars observed in Gaia DR2 and LAMOST DR8
Kun Wang, Péter Németh, Yangping Luo +3
We present the first results from our ongoing project to study extremely low mass (ELM) white dwarfs (WDs) ( 0.3$M_{\sun}$) with the Large Sky Area Multi-Object Fibre Spe…
Physical Properties of 29 sdB+dM Eclipsing Binaries in Zwicky Transient Facility
Min Dai, Xiaodian Chen, Kun Wang +3
The development of large-scale time-domain surveys provides an opportunity to study the physical properties as well as the evolutionary scenario of B-type subdwarfs (sdB) and M-typ…
Hot subdwarf Atmospheric parameters, Kinematics, and Origins -- Based on 1587 hot subdwarf stars observed in Gaia DR2 and LAMOST DR7
Yangping Luo, Peter Nemeth, Kun Wang +2
Based on the Gaia DR2 catalogue of hot subdwarf star candidates, we identified 1587 hot subdwarf stars with spectra in LAMOST DR7. We present atmospheric parameters for these stars…
