An extremely hot white dwarf with a rapidly rotating K-type subgiant companion: UCAC2 46706450
Klaus Werner, Nicole Reindl, Lisa Löbling +5
UCAC2 46706450 is a late-type star with an ultraviolet (UV) excess. It was considered a candidate to establish a sample of FGK stars with white dwarf (WD) companions that can be us…
Measuring the fine structure constant on a white dwarf surface; a detailed analysis of Fe V absorption in G191-B2B
J. Hu, J. K. Webb, T. R. Ayres +12
The gravitational potential phi = GM/Rc^2 at the surface of the white dwarf G191-B2B is 10,000 times stronger than that at the Earth's surface. Numerous photospheric absorption fea…
An in-depth reanalysis of the alleged type Ia supernova progenitor Henize 2-428
N. Reindl, V. Schaffenroth, M. M. Miller Bertolami +5
The nucleus of the planetary nebula Hen2-428 is a short orbital-period (4.2h), double-lined spectroscopic binary, whose status as a potential supernova type Ia progenitor has raise…
