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…
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…
An extremely fast halo hot subdwarf star in a wide binary system
Péter Németh, Eva Ziegerer, Andreas Irrgang +4
New spectroscopic observations of the halo hyper-velocity star candidate SDSS J121150.27+143716.2 ( mag) revealed a cool companion to the hot subdwarf primary. The compone…
A selection of hot subluminous stars in the GALEX survey II. Subdwarf atmospheric parameters
Péter Németh, Adéla Kawka, Stéphane Vennes
We present an update of our low-resolution spectroscopic follow-up and model atmosphere analysis of hot subdwarf stars from the Galaxy Evolution Explorer (GALEX) survey. Targets we…
