An eclipsing post common-envelope system consisting of a pulsating hot subdwarf B star and a brown dwarf companion
V. Schaffenroth, B. N. Barlow, H. Drechsel +1
Hot subdwarf B stars (sdBs) are evolved, core helium-burning objects located on the extreme horizontal branch. Their formation history is still puzzling as the sdB progenitors must…
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…
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…
