Constraints on White Dwarf Hydrogen Layer Masses Using Gravitational Redshifts
Stefan M. Arseneau, J. J. Hermes, Maria E. Camisassa +2
The hydrogen envelope is the outermost layer of a DA white dwarf; it makes up the entirety of the stellar photosphere, and yet its typical extent is difficult to model theoreticall…

Beth A. Biller, Johanna M. Vos, Yifan Zhou +22
We report results from 8 hours of JWST/MIRI LRS spectroscopic monitoring directly followed by 7 hours of JWST/NIRSpec prism spectroscopic monitoring of the benchmark binary brown d…
Magnetic Fields of M Dwarfs from the Pleiades Open Cluster
Fabio Wanderley, Katia Cunha, Oleg Kochukhov +10
Average magnetic field measurements are presented for 62 M-dwarf members of the Pleiades open cluster, derived from Zeeman-enhanced Fe I lines in the H-band. An MCMC methodology wa…
Interstellar Neutral Hydrogen in the Heliosphere: New Horizons Observations in the Context of Models
P. Swaczyna, M. Bzowski, K. Dialynas +12
Interstellar neutral (ISN) hydrogen is the most abundant species in the outer heliosheath and the very local interstellar medium (VLISM). Charge exchange collisions in the outer he…
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…
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…
The Morphology of Asteroidal Dust Around White Dwarf Stars: Optical and Near-infrared Pulsations in G29-38
T. von Hippel, J. Farihi, J. L. Provencal +20
More than 36 years have passed since the discovery of the infrared excess from circumstellar dust orbiting the white dwarf G29-38, which at 17.5 pc it is the nearest and brightest…
