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…
Ultra-deep ATCA imaging of 47 Tucanae reveals a central compact radio source
Alessandro Paduano, Arash Bahramian, James C. A. Miller-Jones +9
We present the results of an ultra-deep radio continuum survey, containing hours of observations, of the Galactic globular cluster 47 Tucanae with the Australia Telescope…
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…
