Circumstellar interaction in the extreme white dwarf merger remnant ZTF\,J1901+1458: A new class of white dwarf merger remnants with X-ray emission
Aayush Desai, Ilaria Caiazzo, Stephane Vennes +31
Double degenerate white dwarf (WD) mergers can exhibit extreme magnetic fields exceeding G and rapid rotation, but their spectral-energy distributions and high-energy emis…
A half-ring of ionized circumstellar material trapped in the magnetosphere of a white dwarf merger remnant
Andrei A. Cristea, Ilaria Caiazzo, Tim Cunningham +31
Many white dwarfs are observed in compact double white dwarf binaries and, through the emission of gravitational waves, a large fraction are destined to merge. The merger remnants…
The total mass of the close, double degenerate (DA+DQ) system NLTT~16249
Stephane Vennes, Adela Kawka
We revisit the binary and stellar properties of the double-degenerate system NLTT 16249. An analysis of new echelle spectra, supported by a joint study of a DQZ velocity template N…
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…
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…
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 <…
