Hot subluminous stars of spectral type B and O are core helium-burning stars at the blue end
of the horizontal branch or have evolved even beyond that stage. Most hot subdwarf stars …

The spectra of singly ionized Strontium and Yttrium (Sr ii and Y ii) have been proposed as
identifications of certain spectral features in the AT2017gfo spectrum. With the growing …

The article presents a review of scientific problems and methods of ultraviolet astronomy,
focusing on perspective scientific problems (directions) whose solution requires UV space …

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 …

UVO 0825+ 15 is a hot bright helium-rich subdwarf which lies in K2 Field 5 and in a sample
of intermediate helium-rich subdwarfs observed with Subaru/HDS. The K2 light curve shows …

Some surviving companions of Type Ia supernovae (SNe Ia) from the white dwarf+ main-
sequence (WD+ MS) channel may evolve to hot subdwarfs. In this paper, we perform stellar …

Hot subdwarfs represent a group of low-mass helium-burning stars formed through binary-
star interactions and include some of the most chemically peculiar stars in the Galaxy. Stellar …

Aims. The present work presents our efforts at identifying new mercury-manganese
(HgMn/CP3) stars using spectra obtained with the Large Sky Area Multi-Object Fiber …
