TIC 378898110: A Bright, Short-Period AM CVn Binary in TESS
Matthew J. Green, J. J. Hermes, Brad N. Barlow +22
AM CVn-type systems are ultracompact, helium-accreting binary systems which are evolutionarily linked to the progenitors of thermonuclear supernovae and are expected to be strong G…
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…
An Eclipsing 47 minute Double White Dwarf Binary at 400 pc
James Munday, P. -E. Tremblay, J. J. Hermes +20
We present the discovery of the eclipsing double white dwarf (WD) binary WDJ 022558.21-692025.38 that has an orbital period of 47.19 min. Following identification with the Transiti…
An emerging and enigmatic spectral class of isolated DAe white dwarfs
Abbigail K. Elms, Pier-Emmanuel Tremblay, Boris T. Gänsicke +9
Two recently discovered white dwarfs, WDJ041246.84754942.26 and WDJ165335.21100116.33, exhibit H and H Balmer line emission similar to stars in the emerging DAHe class,…
Photometric follow-up of 43 new eclipsing white dwarf plus main-sequence binaries from the ZTF survey
Alex J. Brown, Steven G. Parsons, Jan van Roestel +12
Wide-field time-domain photometric sky surveys are now finding hundreds of eclipsing white dwarf plus M dwarf binaries, a population encompassing a wealth of information and potent…
A detailed study of the barium central star of the planetary nebula Abell 70
David Jones, Henri M. J. Boffin, Alex J. Brown +4
We present a detailed study of the barium star at the heart of the planetary nebula Abell 70. Time-series photometry obtained over a period of more than ten years demonstrates that…
