Mapping the Landscape of M Dwarf X-ray Flares: New Discoveries in Context
Imri A. Dickstein, Maayane T. Soumagnac, Eran O. Ofek +4
We report the discovery of 11 X-ray flares from 7 M dwarfs previously unknown to exhibit flaring activity, by cross-matching eROSITA observations of bright, nearby M dwarfs with th…
IK Pegasi and the Double-merger Path to Type Ia Supernovae
Na'ama Hallakoun, Sahar Shahaf, Sagi Ben-Ami +3
Recent Gaia astrometry has revealed thousands of main-sequence + white-dwarf binaries (MS+WD) at separations of ~0.1-10 au, including a subset hosting unusually massive (>~0.8 Msun…
Gaia Barium Dwarfs and Their Ostensibly Ordinary Counterparts
Param Rekhi, Sahar Shahaf, Sagi Ben-Ami +4
The recently identified Gaia population of main-sequence--white dwarf (MS+WD) binaries at separations of , often with moderate eccentricities, is not readily re…
A Census of NUV M-Dwarf Flares Using Archival GALEX Data and the gPhoton2 Pipeline
Param Rekhi, Sagi Ben-Ami, Volker Perdelwitz +1
M-dwarfs are common stellar hosts of habitable-zone exoplanets. NUV radiation can severely impact the atmospheric and surface conditions of such planets, making characterization of…
Ba Enrichment in Gaia MS+WD Binaries: Tracing -Process Element Production
Param Rekhi, Sagi Ben-Ami, Na'ama Hallakoun +3
A large population of intermediate-separation binaries, consisting of a main-sequence (MS) star and a white dwarf (WD), has recently emerged from Gaia's third data release (DR3), p…
