Relativistic Corrections in White Dwarf Asteroseismology
S Reece Boston, Charles R Evans, J Christopher Clemens
With the precision now afforded by modern space-based photometric observations from the retired K2 and current TESS missions, the effects of general relativity (GR) may be detectab…
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…
Kepler and TESS Observations of PG 1159-035
Gabriela Oliveira da Rosa, S. O. Kepler, Alejandro H. Córsico +11
PG 1159-035 is the prototype of the DOV hot pre-white dwarf pulsators. It was observed during the Kepler satellite K2 mission for 69 days in 59 s cadence mode and by the TESS satel…
Lithium pollution of a white dwarf records the accretion of an extrasolar planetesimal
Benjamin C. Kaiser, J. Christopher Clemens, Simon Blouin +4
Tidal disruption and subsequent accretion of planetesimals by white dwarfs can reveal the elemental abundances of rocky bodies in exoplanetary systems. Those abundances provide inf…
Five New Post-Main-Sequence Debris Disks with Gaseous Emission
Erik Dennihy, Siyi Xu, Samuel Lai +13
Observations of debris disks, the products of the collisional evolution of rocky planetesimals, can be used to trace planetary activity across a wide range of stellar types. The mo…
An Isolated White Dwarf with 317-Second Rotation and Magnetic Emission
Joshua S. Reding, J. J. Hermes, Z. Vanderbosch +5
We report the discovery of short-period photometric variability and modulated Zeeman-split hydrogen emission in SDSSJ125230.93-023417.72 (EPIC 228939929), a variable white dwarf st…
