Intermediate-mass runaway and hypervelocity star candidates in DESI DR1
Aakash Bhat, Matti Dorsch, Ulrich Heber +2
Runaway stars ejected from the Galactic disc span a range of velocities, with two extreme regimes of particular interest. Hyper-runaway stars reach velocities approaching the local…
V407 Vul: a triple star system with an AM CVn detectable by gravitational wave observatories
James Munday, Antonio C. Rodriguez, Nicole Reindl +23
The AM CVn class includes mass transferring, ultra-compact double white dwarf binaries with orbital periods on the timescale of minutes. A long-standing puzzle is that none of the…
Hot subdwarf stars from the Hamburg Quasar Survey
Ulrich Heber, Lennard Kufleitner, Matti Dorsch +4
Hot subluminous stars (sdO/B) are evolved low mass stars originating from red giants that lost their envelope almost entirely. The multitude of observed phenomena imply that severa…
Three new hot hydrogen-deficient pre-white dwarfs
Klaus Werner, Nicole Reindl, Max Pritzkuleit +1
We have detected three new hydrogen-deficient (H < 0.001 mass fraction) pre-white dwarfs (WDs) with helium-dominated atmospheres. The first object is a relatively cool PG1159 star…
White dwarf and subdwarf stars in the Sloan Digital Sky Survey Data Release 16
S. O. Kepler, Detlev Koester, Ingrid Pelisoli +2
White dwarfs are the end state of the evolution of more than 97% of all stars, and therefore carry information on the structure and evolution of the Galaxy through their luminosity…
Confirming new white dwarf-ultracool dwarf binary candidates
Miriam Hogg, Sarah Casewell, Graham Wynn +8
We present the results of a study to discover prospective new white dwarf-L dwarf binaries as identified by their near-infrared excesses in the UKIDSS catalogue. We obtained optica…
