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…

A 500 pc volume-limited sample of hot subluminous stars I. Space density, scale height, and population properties

H. Dawson, S. Geier, U. Heber +25

We present the first volume-limited sample of spectroscopically confirmed hot subluminous stars out to 500 pc, defined using the accurate parallax measurements from the {\em Gaia}…

A self-synthesized origin of heavy metals in hot subdwarf stars?

T. Battich, M. M. Miller Bertolami, A. M. Serenelli +2

Some He-rich hot subdwarf stars (He-sdOBs) present high abundances of trans-iron elements, such as Sr, Y, Zr and Pb. Diffusion processes are important in hot subdwarf stars, and it…

The bright blue side of the night sky: Spectroscopic survey of bright and hot (pre-) white dwarfs

Nicole Reindl, Ramazan Islami, Klaus Werner +10

We report on the spectroscopic confirmation of 68 new bright ( mag) and blue (pre-)white dwarfs (WDs). This finding has allowed us to almost double the number of the 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…

Discovery of a highly magnetic He-sdO star from a double-degenerate binary merger

M. Dorsch, N. Reindl, I. Pelisoli +4

Helium-rich hot subdwarf stars of spectral type O (He-sdO) are considered prime candidates for stellar merger remnants. Such events should lead to the generation of strong magnetic…

Properties and applications of a predicted population of runaway He-sdO/B stars ejected from single degenerate He-donor SNe

P. Neunteufel, H. Preece, M. Kruckow +4

This study builds on previous works, producing the most extensive prediction of the properties of such a hypothetical population to date, taking into account both Chandrasekhar and…
