The orbits of subdwarf B + main-sequence binaries. I: The sdB+G0 system PG 1104+243
J. Vos, R. H. Östensen, P. Degroote +18
The predicted orbital period histogram of an sdB population is bimodal with a peak at short (< 10 days) and long (> 250 days) periods. Observationally, there are many short-period…
A Radial Velocity Study of Composite-Spectra Hot Subdwarf Stars with the Hobby-Eberly Telescope
Brad N. Barlow, Richard A. Wade, Sandra E. Liss +2
Many hot subdwarf stars show composite spectral energy distributions indicative of cool main sequence companions. Binary population synthesis (BPS) models demonstrate such systems…
Spectroscopic follow-up of UV-excess objects selected from the UVEX survey
Kars Verbeek, Paul J. Groot, Simone Scaringi +17
We present the results of the first spectroscopic follow-up of 132 optically blue UV-excess sources selected from the UV-excess survey of the Northern Galactic Plane (UVEX). The UV…
MUCHFUSS - Massive Unseen Companions to Hot Faint Underluminous Stars from SDSS
S. Geier, V. Schaffenroth, H. Hirsch +15
The project Massive Unseen Companions to Hot Faint Underluminous Stars from SDSS (MUCHFUSS) aims at finding hot subdwarf stars with massive compact companions (white dwarfs with ma…
Three ways to solve the orbit of KIC11558725: a 10 day beaming sdB+WD binary with a pulsating subdwarf
J. H. Telting, R. H. Østensen, A. S. Baran +16
The recently discovered subdwarf B (sdB) pulsator KIC11558725 features a rich g-mode frequency spectrum, with a few low-amplitude p-modes at short periods, and is a promising targe…
A pulsation zoo in the hot subdwarf B star KIC 10139564 observed by Kepler
A. S. Baran, M. D. Reed, D. Stello +13
We present our analyses of 15 months of Kepler data on KIC 10139564. We detected 57 periodicities with a variety of properties not previously observed all together in one pulsating…
