A cool, magnetic white dwarf accreting planetary debris
Stephane Vennes, Adela Kawka, Beth L. Klein +3
We present an analysis of spectroscopic data of the cool, highly magnetic and polluted white dwarf 2MASS J0916-4215. The atmosphere of the white dwarf is dominated by hydrogen, but…
Transient fading X-ray emission detected during the optical rise of a tidal disruption event
A. Malyali, A. Rau, C. Bonnerot +9
We report on the SRG/eROSITA detection of ultra-soft ( eV) X-ray emission ( erg s) from the tidal disruptio…
A rotating white dwarf shows different compositions on its opposite faces
Ilaria Caiazzo, Kevin B. Burdge, Pier-Emmanuel Tremblay +35
White dwarfs, the extremely dense remnants left behind by most stars after their death, are characterised by a mass comparable to that of the Sun compressed into the size of an Ear…
EPIC 206197016: A very hot white dwarf orbited by a strongly irradiated red dwarf
J. Krticka, A. Kawka, Z. Mikulasek +7
Very precise satellite photometry has revealed a large number of variable stars whose variability is caused either by surface spots or by binarity. Detailed studies of such variabl…
The non-explosive stellar merging origin of the ultra-massive carbon-rich white dwarfs
Adela Kawka, Lilia Ferrario, Stephane Vennes
We have investigated the origin of a sub-class of carbon-polluted white dwarfs (DQ) originally identified as the ``hot DQ" white dwarfs. These objects are relatively hot (10 000 <…
The rebrightening of a ROSAT-selected tidal disruption event: repeated weak partial disruption flares from a quiescent galaxy?
A. Malyali, Z. Liu, A. Rau +11
The ROSAT-selected tidal disruption event (TDE) candidate RX J133157.6-324319.7 (J1331), was detected in 1993 as a bright (0.2-2 keV flux of erg s$^…
