Searching for Massive Remnant Planetary System Hosts with White Dwarf Gaia XP Spectra
Lou Baya Ould Rouis, J. J. Hermes, Pierre Bergeron +5
Remnant planetary systems around massive white dwarfs () are intrinsically rare and remain poorly characterized. As the evolutionary endpoints of i…
A Galactic intermediate-mass stripped star with a Wolf-Rayet-like wind
Johanna Müller-Horn, Kareem El-Badry, Andreas A. C. Sander +17
Binary interaction in massive stars is expected to produce a large population of intermediate-mass (- M) envelope-stripped stars, yet such objects have remained elusi…
SRG/eROSITA X-ray selected cataclysmic variable candidates observed in SDSS-V DR20
J. Brink, A. D. Schwope, K. G. Pradeep +35
We report on the spectroscopic observations obtained during SDSS-V DR20 of accreting compact binaries (ACB), specifically the cataclysmic variables (CVs), that were identified as l…
An Ultramassive White Dwarf with a Likely Oxygen-Neon Core
Stefan M. Arseneau, J. J. Hermes, Vedant Chandra +4
The core composition of ultramassive white dwarfs remains an open question in stellar evolution. The carbon content of white dwarf cores is critical to their role as progenitors of…
The DECam MAGIC Survey Mapping the Ancient Galaxy in CaHK: Overview and Summary of Early Science
A. Chiti, A. Drlica-Wagner, A. B. Pace +42
We present the DECam Mapping the Ancient Galaxy in CaHK (MAGIC) survey, a 54-night NOIRLab Survey Program to image 5,000deg of the southern hemisphere using a meta…
White dwarf planetary systems in the ultraviolet
Jamie Williams, Amy Bonsor, Boris Gänsicke +9
Almost every known planet host will evolve into a white dwarf, and the surviving planetary material will continue to orbit this stellar remnant. Asteroids perturbed onto star-grazi…
