The eROSITA Final Equatorial Depth Survey (eFEDS): SDSS spectroscopic observations of X-ray sources

Catarina Aydar, Andrea Merloni, Tom Dwelly +45

We present one of the largest uniform optical spectroscopic surveys of X-ray selected sources to date that were observed as a pilot study for the Black Hole Mapper (BHM) survey. Th…

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…

A spectroscopic and kinematic survey of fast hot subdwarfs

S. Geier, U. Heber, A. Irrgang +19

Hot subdwarfs (sdO/B) are the stripped helium cores of red giants formed by binary interactions. Close hot subdwarf binaries with massive white dwarf companions have been proposed…

Compact white-dwarf binaries in the combined SRG/eROSITA/SDSS eFEDS survey

A. Schwope, J. Kurpas, P. Baecke +22

Aims. Compact white-dwarf binaries are selected from spectra obtained in the early SDSS-V plate program. A dedicated set of SDSS plate observations were carried out in the eFEDS fi…

Effective Temperatures of Cataclysmic Variable White Dwarfs as a Probe of their Evolution

A. F. Pala, B. T. Gänsicke, D. Townsley +29

We present HST spectroscopy for 45 cataclysmic variables (CVs), observed with HST/COS and HST/STIS. For 36 CVs, the white dwarf is recognisable through its broad Ly absorption p…

A gaseous metal disk around a white dwarf

B. T. Gaensicke, T. R. Marsh, J. Southworth +1

The destiny of planetary systems through the late evolution of their host stars is very uncertain. We report a metal-rich gas disk around a moderately hot and young white dwarf. A…
