A Be Star + He Star Binary as an Indicator of a Binary Mass Transfer Phase
The Astrophysical JournalThe rapid rotation of Be stars is supposed to mainly originate from binary evolution. In recent years, more and more Be stars with helium (He) star companions have been discovered, which provides a significant opportunity to study binary interaction ...

A NICER Viewing Angle on the Accretion Stream of Vela X-1
The Astrophysical Journal, 2023 Vela X-1 is the archetypal eclipsing high-mass X-ray binary, composed of a neutron star (NS) accreting the B-star wind. It was observed by nearly all X-ray observatories, often multiple times, featuring a rich spectrum of variable emission lines. However,

Binary Stars in Planetary Nebulae [PDF]
, 2013 When a star like the sun dies, it swells into a red giant and then expels its outer layers to form a planetary nebula. Eventually the outer layers leave the leftover core and it becomes a white dwarf.

On the universal outcome of star-formation: Is there a link between stars and brown-dwarfs?
, 2003 (abridged) The recent evidence obtained by Briceno et al. that star-formation in Taurus-Auriga (TA) may be producing significantly fewer brown dwarfs (BDs) per star than the ONC is investigated by setting up a realistic model stellar plus BD population ...

Hot subdwarf formation: Confronting theory with observation
EPJ Web of Conferences, 2013 The formation of hot subdwarf stars is still unclear. Both single-star and binary scenarios have been proposed to explain the properties of these evolved stars situated at the extreme blue end of the horizontal branch. The observational evidence gathered

Binary Star Orbits. VI. The Interferometric-spectroscopic Binary 73 Leo
The Astronomical JournalDiscordances in radial-velocity measurements of 73 Leonis, made more than a century ago, gave rise to the first suggestion that this fifth-magnitude star was a binary system, but it was 40 yr before an accurate investigation of the object commenced, and ...

Proceedings of the International Astronomical Union, 2006 Only a handful of binary central stars of planetary nebulae (PNe) are known today, due to the difficulty of detecting their companions. Preliminary results from radial velocity surveys, however, seem to indicate that binarity plays a fundamental,rather than marginal role in the evolution of PNe and that the close binary fraction might be much larger ...
