Hot subdwarf stars from the Hamburg Quasar Survey
Ulrich Heber, Lennard Kufleitner, Matti Dorsch +4
Hot subluminous stars (sdO/B) are evolved low mass stars originating from red giants that lost their envelope almost entirely. The multitude of observed phenomena imply that severa…
Discovery of a double white dwarf in the Galactic globular cluster NGC 6397
Fabian Göttgens, Marilyn Latour, Ulrich Heber +4
Binaries in the cores of globular clusters are known to prevent the gravitational collapse of the cluster, and simulations predict that the core of NGC 6397 contains a large number…
A 500 pc volume-limited sample of hot subluminous stars II. Atmospheric parameters, mass distribution, and kinematics
H. Dawson, M. Dorsch, S. Geier +30
We present a quantitative spectroscopic and kinematic analysis of a volume-complete sample of hot subluminous stars within 500 pc of the Sun, assembled using accurate parallax meas…
The Arizona-Montréal spectroscopic survey of hot subluminous stars
M. Latour, E. M. Green, M. Dorsch +6
Hot subdwarf B (sdB) and O (sdO) type stars are evolved helium-burning objects that lost their hydrogen envelope before the helium flash when their progenitors were close to the ti…
Spectroscopic Observations of Four Candidates for Blue Large-Amplitude Pulsators. No BLAPs at High Galactic Latitudes
P. Pietrukowicz, M. Latour, F. Di Mille +3
We have obtained spectroscopic observations for four short-period variable objects detected in ZTF, Gaia, and Pan-STARRS (ZGP) data and classified as Blue Large-Amplitude Pulsators…
Quantitative spectral analysis of the sdB star HD 188112: a helium-core white dwarf progenitor
M. Latour, U. Heber, A. Irrgang +7
HD 188112 is a bright (V = 10.2 mag) hot subdwarf B (sdB) star with a mass too low to ignite core helium burning and is therefore considered as a pre-extremely low mass (ELM) white…
