Hot subdwarf stars in close-up view I. Rotational properties of subdwarf B stars in close binary systems and nature of their unseen companions
Stephan Geier,Ulrich Heber,Ph. Podsiadlowski,H. Edelmann,Ralf Napiwotzki,Thomas Kupfer,S. Mueller +6 more
TL;DR: In this paper, the authors measured the projected rotational velocities of a large sdB binary sample from high-resolution spectra and analyzed a sample of 51 sdB stars in close binaries, 40 of which have known orbital parameters.
Massive unseen companions to hot faint underluminous stars from SDSS (MUCHFUSS) - Analysis of seven close subdwarf B binaries
Stephan Geier,Pierre F. L. Maxted,R. Napiwotzki,R. H. Oestensen,Ulrich Heber,H. Hirsch,Thomas Kupfer,S. Mueller,A. Tillich,Brad N. Barlow,R. Oreiro,T. A. Ottosen,Chris M. Copperwheat,Boris T. Gaensicke,T. R. Marsh +14 more
TL;DR: The Massive Unseen Companions to Hot Faint Underluminous Stars from SDSS (MUCHFUSS) project as discussed by the authors aims at finding hot subdwarf stars with massive compact companions like massive white dwarfs (M > 1.0 Msun), neutron stars or stellar mass black holes.
Orbital solutions of eight close sdB binaries and constraints on the nature of the unseen companions
