A spectroscopic and kinematic survey of fast hot subdwarfs
S. Geier, U. Heber, A. Irrgang +19
Hot subdwarfs (sdO/B) are the stripped helium cores of red giants formed by binary interactions. Close hot subdwarf binaries with massive white dwarf companions have been proposed…
A comprehensive search for hot subdwarf stars using Gaia and TESS I. Pulsating hot subdwarf B stars
Murat Uzundag, Jurek Krzesinski, Ingrid Pelisoli +4
Hot subdwarf B (sdB) stars are evolved, subluminous, helium-burning stars, most likely formed when red-giant stars lose their hydrogen envelope via interactions with close companio…
MELCHIORS: The Mercator Library of High Resolution Stellar Spectroscopy
P. Royer, T. Merle, K. Dsilva +71
Over the past decades, libraries of stellar spectra have been used in a large variety of science cases, including as sources of reference spectra for a given object or a given spec…
Looking into the cradle of the grave: J22564-5910, a young post-merger hot subdwarf?
Joris Vos, Ingrid Pelisoli, Jan Budaj +10
We present the discovery of J22564-5910, a new type of hot subdwarf (sdB) which shows evidence of gas present in the system and has shallow, multi-peaked hydrogen and helium lines…
Evolutionary Constraints on the Long-period Subdwarf B Binary PG 1018-047
J. Deca, J. Vos, P. Németh +4
We have revisited the sdB+K-star long-period binary PG 1018-047 based on 20 new high-resolution VLT/UVES spectra that provided regular coverage over a period of more than 26 months…
The population of hot subdwarf stars studied with Gaia I. The catalogue of known hot subdwarf stars
S. Geier, R. H. Østensen, P. Nemeth +5
In preparation for the upcoming all-sky data releases of the Gaia mission we compiled a catalogue of known hot subdwarf stars and candidates drawn from the literature and yet unpub…
