HD188112: Supernova Ia progenitor?
M. Latour, A. Irrgang, U. Heber +1
HD188112 is an extremely low mass white dwarf in a close binary system. According to a previous study, the mass of HD188112 is 0.24 Msun and a lower limit of 0.73 Msun could…
The catalogue of radial velocity variable hot subluminous stars from the MUCHFUSS project
S. Geier, T. Kupfer, U. Heber +13
The project Massive Unseen Companions to Hot Faint Underluminous Stars from SDSS (MUCHFUSS) aims to find sdBs with compact companions like massive white dwarfs, neutron stars or bl…
Observations of the extreme runaway HD271791: nucleosynthesis in a core-collapse supernova
V. Schaffenroth, N. Przybilla, K. Butler +2
Some young, massive stars can be found in the Galactic halo. As star formation is unlikely to occur in the halo, they must have been formed in the disk and been ejected shortly aft…
The population of white dwarf binaries with hot subdwarf companions
S. Geier, T. Kupfer, U. Heber +7
Hot subdwarfs (sdBs) are core helium-burning stars, which lost almost their entire hydrogen envelope in the red-giant phase. Since a high fraction of those stars are in close binar…
Hot subdwarf binaries from the MUCHFUSS project - Analysis of 12 new systems and a study of the short-period binary population
T. Kupfer, S. Geier, U. Heber +6
The project Massive Unseen Companions to Hot Faint Underluminous Stars from SDSS (MUCHFUSS) aims at finding hot subdwarf stars with massive compact companions like massive white dw…
