A hot subdwarf-white dwarf super-Chandrasekhar candidate supernova Ia progenitor
Ingrid Pelisoli, P. Neunteufel, S. Geier +8
Supernova Ia are bright explosive events that can be used to estimate cosmological distances, allowing us to study the expansion of the Universe. They are understood to result from…
Eclipsing Binaries Found by the EREBOS Project: Gaia DR2 6097540197980557440 -- A Deeply Eclipsing sdB+dM System
Kyle A. Corcoran, Brad N. Barlow, Veronika Schaffenroth +3
We present time-series spectroscopy and photometry of Gaia DR2 6097540197980557440, a new deeply-eclipsing hot subdwarf B (sdB) + M dwarf (dM) binary. We discovered this object dur…
New X-ray observations of the hot subdwarf binary HD49798 / RXJ0648.0-4418
S. Mereghetti, F. Pintore, T. Rauch +7
HD49798 / RXJ0648.0-4418 is the only confirmed X-ray binary in which the mass donor is a hot subdwarf star of O spectral type and, most likely, it contains a massive white dwarf (1…
Mysterious, Variable, and Extremely Hot: White Dwarfs Showing Ultra-High Excitation Lines I. Photometric Variability
Nicole Reindl, Veronika Schaffenroth, Semih Filiz +3
About 10% of all stars exhibit absorption lines of ultra-high excited (UHE) metals (e.g. OVIII) in their optical spectra when entering the white dwarf cooling sequence. The recent…
