Binaries discovered by the MUCHFUSS project; FBS 0117+396: An sdB+dM binary with a pulsating primary
R. H. Østensen, S. Geier, V. Schaffenroth +16
The project Massive Unseen Companions to Hot Faint Underluminous Stars from SDSS (muchfuss) aims to discover subdwarf-B stars with massive compact companions such as overmassive wh…
Finding compact hot subdwarf binaries in the Galactic disc
T. Kupfer, S. Geier, A. Faye McLeod +15
We started a new project which aims to find compact hot subdwarf binaries at low Galactic latitudes. Targets are selected from several photometric surveys and a spectroscopic follo…
Multi-periodic pulsations of a stripped red giant star in an eclipsing binary
Pierre F. L. Maxted, Aldo M. Serenelli, Andrea Miglio +8
Low mass white dwarfs are the remnants of disrupted red giant stars in binary millisecond pulsars and other exotic binary star systems. Some low mass white dwarfs cool rapidly, whi…
A progenitor binary and an ejected mass donor remnant of faint type Ia supernovae
S. Geier, T. R. Marsh, B. Wang +17
Type Ia supernovae (SN Ia) are the most important standard candles for measuring the expansion history of the universe. The thermonuclear explosion of a white dwarf can explain the…
A new bright eclipsing hot subdwarf binary from the ASAS and SuperWASP surveys
V. Schaffenroth, S. Geier, H. Drechsel +5
We report the discovery of a bright (V=11.6 mag) eclipsing hot subdwarf binary of spectral type B with a late main sequence companion from the All Sky Automated Survey (ASAS 102322…
