The fastest hot subdwarfs revisited
Ulrich Heber
Hyper-velocity stars (HVS) are enigmatic objects because they are travelling so fast that they escape from the Galaxy. Among hot subdwarfs, only one such star is known, the He-sdO…
The OmegaWhite Survey for Short-Period Variable Stars VII: High amplitude, short period blue variables
G. Ramsay, P. A. Woudt, T. Kupfer +11
Blue Large Amplitude Pulsators (BLAPs) are a relatively new class of blue variable stars showing periodic variations in their light curves with periods shorter than a few tens of m…
Heavy-metal enrichment of intermediate He-sdOB stars: the pulsators Feige 46 and LS IV -14 116 revisited
M. Dorsch, M. Latour, U. Heber +3
Hot subdwarf stars of types O and B represent a poorly understood phase in the evolution of low-mass stars. Many subdwarfs show rich oscillations and are among the most chemically…
Heavy-metal enrichment in the intermediate He-sdOB pulsator Feige 46
Marilyn Latour, Matti Dorsch, Ulrich Heber
The intermediate He-enriched hot subdwarf star Feige 46 was recently reported as the second member of the V366 Aqr (or He-sdOBV) pulsating class. Feige 46 is very similar to the pr…
The EREBOS project -- Investigating the effect of substellar and low-mass stellar companions on late stellar evolution
V. Schaffenroth, B. N. Barlow, S. Geier +14
Eclipsing post-common envelope binaries are highly important for resolving the poorly understood, very short-lived common envelope phase. Most hot subdwarfs (sdO/Bs) are the bare H…
Heavy metals in intermediate He-rich hot subdwarfs: The chemical composition of HZ44 and HD127493
Matti Dorsch, Marilyn Latour, Ulrich Heber
Hot subluminous stars can be spectroscopically classified as subdwarf B (sdB) and O (sdO) stars. While the latter are predominantly hydrogen deficient, the former are mostly helium…
