Quantitative spectral analysis of the sdB star HD 188112: a helium-core white dwarf progenitor
M. Latour, U. Heber, A. Irrgang +7
HD 188112 is a bright (V = 10.2 mag) hot subdwarf B (sdB) star with a mass too low to ignite core helium burning and is therefore considered as a pre-extremely low mass (ELM) white…
Candidate hypervelocity stars of spectral type G and K revisited
E. Ziegerer, M. Volkert, U. Heber +3
Hypervelocity stars (HVS) move so fast that they are unbound to the Galaxy. When they were first discovered in 2005, dynamical ejection from the supermassive black hole (SMBH) in t…
The fastest unbound star in our Galaxy ejected by a thermonuclear supernova
S. Geier, F. Fürst, E. Ziegerer +17
Hypervelocity stars (HVS) travel with velocities so high, that they exceed the escape velocity of the Galaxy. Several acceleration mechanisms have been discussed. Only one HVS (US…
HD188112: Supernova Ia progenitor?
M. Latour, A. Irrgang, U. Heber +1
HD188112 is an extremely low mass white dwarf in a close binary system. According to a previous study, the mass of HD188112 is 0.24 Msun and a lower limit of 0.73 Msun could…
Observations of the extreme runaway HD271791: nucleosynthesis in a core-collapse supernova
V. Schaffenroth, N. Przybilla, K. Butler +2
Some young, massive stars can be found in the Galactic halo. As star formation is unlikely to occur in the halo, they must have been formed in the disk and been ejected shortly aft…
