A comprehensive search for hot subdwarf stars using Gaia and TESS
Hot subdwarf B (sdB) stars are evolved, subluminous, helium-burning stars that most likely form when red giant stars loose their hydrogen envelope via interactions with close companions. They play an important role in our understanding of binary evolution, stellar atmospheres, and interiors.

The evolution of a hot subdwarf: observations of the pulsating subdwarf B star Feige~48
Since pulsating subdwarf B (sdBV or EC14026) stars were first discovered (Kilkenny et al, 1997), observational efforts have tried to realize their potential for constraining the interior physics of extreme horizontal branch (EHB) stars. Difficulties encountered along the way include uncertain mode identifications and a lack of stable pulsation mode ...

The composition of Kapteyn's star and the M subdwarfs.
The metal abundance of the nearby M subdwarf Kapteyn's star is obtained from a 10 A mm/sup -1/ spectrum in the near-infrared. The weighted mean value of (M/H) is -0.55 +- 0.15 (p.e.), confirming an earlier estimate from the strength of the TiO bands. The O/C ratio in Kapteyn's star is within a factor of 2 of the solar value.
