Constraints on Remnant Planetary Systems as a Function of Main-Sequence Mass with HST/COS
Lou Baya Ould Rouis, J. J. Hermes, Boris T. Gänsicke +8
As the descendants of stars with masses less than 8 M on the main sequence, white dwarfs provide a unique way to constrain planetary occurrence around intermediate-mass s…
Thirty Two New Bright ZZ Ceti Stars from TESS: Adding Cycles 4 and 5
Alejandra D. Romero, S. O. Kepler, Gabriela Oliveira da Rosa +1
Analyzing all 120 s and 20 s light curves obtained by the TESS satellite up to Sector 69 - the end of the fifth year of observations - for all known white dwarfs and white dwarf ca…
Using 3.4-m Variability towards White Dwarfs as a Signpost of Remnant Planetary Systems
Joseph A. Guidry, J. J. Hermes, Kishalay De +3
Roughly 2% of white dwarfs harbor planetary debris disks detectable via infrared excesses, but only a few percent of these disks show a gaseous component, distinguished by their do…
The PLATO Mission
Heike Rauer, Conny Aerts, Juan Cabrera +842
PLATO (PLAnetary Transits and Oscillations of stars) is ESA's M3 mission designed to detect and characterise extrasolar planets and perform asteroseismic monitoring of a large numb…
Measuring White Dwarf Variability from Sparsely Sampled Gaia DR3 Multi-Epoch Photometry
Maya Steen, J. J. Hermes, Joseph A. Guidry +5
White dwarf stars are ubiquitous in the Galaxy, and are essential to understanding stellar evolution. While most white dwarfs are photometrically stable and reliable flux standards…
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…
Rotation at the Fully Convective Boundary: Insights from Wide WD + MS Binary Systems
Federica Chiti, Jennifer L. van Saders, Tyler M. Heintz +5
Gyrochronology, a valuable tool for determining ages of low-mass stars where other techniques fail, relies on accurate calibration. We present a sample of 185 wide ( au) wh…
Flares hunting in hot subdwarf and white dwarf stars from Cycles 1-5 of TESS photometry
Keyu Xing, Weikai Zong, Roberto Silvotti +9
Stellar flares are critical phenomena on stellar surfaces, which are closely tied to stellar magnetism. While extensively studied in main-sequence (MS) stars, their occurrence in e…
