The Origins of Lithium Enhancement in Polluted White Dwarfs

Benjamin C. Kaiser, J. Christopher Clemens, Simon Blouin +4

The bulk abundances of exoplanetesimals can be measured when they are accreted by white dwarfs. Recently, lithium from the accretion of exoplanetesimals was detected in relatively…

MAUVE: An Ultraviolet Astrophysics Probe Mission Concept

Mayura Balakrishnan, Rory Bowens, Fernando Cruz Aguirre +18

We present the mission concept "Mission to Analyze the UltraViolet universE" (MAUVE), a wide-field spectrometer and imager conceived during the inaugural NASA Astrophysics Mission…

A Test of Spectroscopic Age Estimates of White Dwarfs using Wide WD+WD Binaries

Tyler M. Heintz, J. J. Hermes, P. -E. Tremblay +4

White dwarf stars have been used for decades as precise and accurate age indicators. This work presents a test of the reliability of white dwarf total ages when spectroscopic obser…

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…

Discovery of 74 new bright ZZ Ceti stars in the first three years of TESS

A. D. Romero, S. O. Kepler, J. J. Hermes +17

We report the discovery of 74 new pulsating DA white dwarf stars, or ZZ Cetis, from the data obtained by the Transiting Exoplanet Survey Satellite (TESS) mission, from Sectors 1 to…

Velocity-imaging the rapidly precessing planetary disc around the white dwarf HE 1349-2305 using Doppler tomography

Christopher J. Manser, Erik Dennihy, Boris T. Gänsicke +11

The presence of planetary material in white dwarf atmospheres, thought to be accreted from a dusty debris disc produced via the tidal disruption of a planetesimal, is common. Appro…
