There are a number of reasons for studying hot subdwarf pulsation; the most obvious being
that these stars remain a poorly understood late-stage of stellar evolution and knowledge of …

This paper reviews recent seismic findings from Kepler and K2 data. Using three years of
short cadence Kepler (K1) data, it is possible to examine time evolution of pulsations in an …

ABSTRACT A medium-and high-resolution spectroscopic survey of helium-rich hot
subdwarfs is being carried out using the Southern African Large Telescope (SALT) …

Context. Hot subluminous stars can be spectroscopically classified as subdwarf B (sdB) and
O (sdO) stars. While the latter are predominantly hydrogen deficient, the former are mostly …

Three hundred and eighty eight hot subdwarf stars have been identified by using the
Hertzsprung–Russell (HR) diagram built from the second data release of the Gaia mission …

Hot subdwarf stars of spectral types O and B represent a poorly understood phase in the
evolution of low-mass stars, in particular of close compact binaries. A variety of phenomena …

Helium-burning hot subdwarf stars of spectral types O and B (sdO/B) are thought to be
produced through various types of binary interactions. The helium-rich hot subdwarf star EC …

The discovery of extremely zirconium-and lead-rich surfaces amongst a small subgroup of
hot subdwarfs has provoked questions pertaining to chemical peculiarity in hot star …

Context. The∈ mechanism is a self-excitation mechanism of stellar pulsations that acts in
regions inside the star where nuclear burning takes place. It has been shown that the∈ …
