A 500 pc volume-limited sample of hot subluminous stars II. Atmospheric parameters, mass distribution, and kinematics
H. Dawson, M. Dorsch, S. Geier +30
We present a quantitative spectroscopic and kinematic analysis of a volume-complete sample of hot subluminous stars within 500 pc of the Sun, assembled using accurate parallax meas…
He-star donor pathway for the hypervelocity star D6-2
Abinaya Swaruba Rajamuthukumar, Ruediger Pakmor, Stephen Justham +2
Type Ia supernovae are thermonuclear explosions of white dwarfs, yet the nature of their progenitor systems remains uncertain. Recent discoveries of hypervelocity stars provide uni…
The -processes nucleosynthesis during the formation of He-rich hot-subdwarf stars
T. Battich, M. M. Miller Bertolami, A. Weiss +3
It has been shown that proton ingestion episodes can happen in the formation of hot-subdwarf stars, and that neutron-capture processes are possible in those cases. Moreover, some h…
Coping with loss: Stability of mass transfer from post-main sequence donor stars
K. D. Temmink, O. R. Pols, S. Justham +2
The stability of mass transfer is critical in determining pathways towards various kinds of compact binaries, such as compact main-sequence white-dwarf binaries, and transients, su…
