Fast hot subdwarfs spectroscopy and kinematics
Hot subdwarfs (sdO/B) are the stripped helium cores of red giants formed via binary interactions. Close hot subdwarf binaries with massive white dwarf companions have been... -
SDSS DR16 white dwarf and subdwarf stars
White dwarfs are the end state of the evolution of more than 97 per cent of all stars, and therefore carry information on the structure and evolution of the Galaxy through their... -
White dwarf and subdwarf stars in SDSS DR14
White dwarfs carry information on the structure and evolution of the Galaxy, especially through their luminosity function and initial-to-final mass relation. Very cool white... -
Extremely-low mass white dwarf star
The so-called sdA stars are defined by having H-rich spectra and surface gravities similar to hot subdwarf stars, but effective temperature below the zero-age horizontal branch.... -
Hot subluminous stars 500pc volume-limited sample
We present the first volume-limited sample of spectroscopically confirmed hot subluminous stars out to 500pc, defined using the accurate parallax measurements from the Gaia... -
Pulsating hot subdwarf B stars
Hot subdwarf B (sdB) stars are evolved, subluminous, helium-burning stars, most likely formed when red-giant stars lose their hydrogen envelope via interactions with close... -
Hot subdwarf stars studied with Gaia
In light of substantial new discoveries of hot subdwarfs by ongoing spectroscopic surveys and the availability of the Gaia mission Early Data Release 3 (EDR3), we compiled new... -
Hot subdwarf stars Radial velocity variability
Hot subdwarf stars represent a late and peculiar stage in the evolution of low-mass stars, since they are likely formed by close binary interactions. In this work, we perform a... -
Hot subdwarf stars binarity
Hot subdwarfs are core-helium burning stars that show lower masses and higher temperatures than canonical horizontal branch stars. They are believed to be formed when a red... -
Seven new pulsating sdA stars
The nature of the recently identified "sdA" spectroscopic class of star is not well understood. The thousands of known sdAs have H-dominated spectra, spectroscopic surface...
