Unveiling the properties of pulsating low-mass helium-core white dwarfs through TESS asteroseismology I. First results
Leila M. Calcaferro, Nikoo Hosseininezhad, Murat Uzundag +4
Recent space-based photometry, particularly from TESS, has opened new possibilities for probing the internal structure of low-mass (LM) helium (He)-core white dwarfs (WDs). We pres…
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…
Discovery of Dipolar Chromospheres in Two White Dwarfs
J. Farihi, J. J. Hermes, S. P. Littlefair +3
This paper reports the ULTRACAM discovery of dipolar surface spots in two cool magnetic white dwarfs with Balmer emission lines, while a third system exhibits a single spot, simila…
Cataclysmic Variables from Sloan Digital Sky Survey V -- the search for period bouncers continues
K. Inight, Boris T. Gänsicke, A. Schwope +25
SDSS-V is carrying out a dedicated survey for white dwarfs, single and in binaries, and we report the analysis of the spectroscopy of cataclysmic variables (CVs) and CV candidates…
Two New White Dwarfs With Variable Magnetic Balmer Emission Lines
Joshua S. Reding, J. J. Hermes, J. C. Clemens +2
We report the discovery of two apparently isolated stellar remnants that exhibit rotationally modulated magnetic Balmer emission, adding to the emerging DAHe class of white dwarf s…
Exploring the internal rotation of the extremely low-mass He-core white dwarf GD 278 with TESS asteroseismology
Leila M. Calcaferro, Alejandro H. Córsico, Leandro G. Althaus +2
(Abridged) We present an exploration of the internal rotation of GD 278, the first pulsating extremely low-mass white dwarf that shows rotational splittings within its periodogram.…
