Hot subdwarf stars identified in Gaia DR2 with spectra of LAMOST DR6 and DR7 I. Single-lined spectra
Zhenxin Lei, Jingkun Zhao, Péter Németh +1
182 single-lined hot subdwarf stars are identified by using spectra from the sixth and seventh data release (DR6 and DR7) of the Large Sky Area Multi-Object Fibre Spectroscopic Tel…
Searching for Hot Subdwarf Stars in LAMOST DR1-II. Pure spectroscopic identification method for hot subdwarfs
Zhenxin Lei, Yude Bu, Jingkun Zhao +2
Employing a new machine learning method, named hierarchical extreme learning machine (HELM) algorithm, we identified 56 hot subdwarf stars in the first data release (DR1) of the La…
PB 8783: the first sdO star suitable for asteroseismic modeling?
Valerie Van Grootel, Suzanna K. Randall, Marilyn Latour +5
Pulsating hot B subdwarf (sdB) stars, which are core-He burning objects, are one of the showcases of asteroseismology. Thanks to the combination of rich pulsation spectra and state…
The orbital period -- mass ratio relation of wide sdB+MS binaries and its application to the stability of RLOF
Joris Vos, Maja Vucković, Xuefei Chen +5
Wide binaries with hot subdwarf-B (sdB) primaries and main sequence companions are thought to form only through stable Roche lobe overflow (RLOF) of the sdB progenitor near the tip…
Composite hot-subdwarf binaries -- I. The spectroscopically confirmed sdB sample
Joris Vos, Péter Németh, Maja Vučković +2
Hot subdwarf-B (sdB) stars in long-period binaries are found to be on eccentric orbits, even though current binary-evolution theory predicts these objects to be circularised before…
Close binary progenitors and ejected companions of thermonuclear supernovae
S. Geier, T. Kupfer, U. Heber +8
Hot subdwarf stars (sdO/Bs) are evolved core helium-burning stars with very thin hydrogen envelopes, which can be formed by common envelope ejection. Close sdB binaries with massiv…
