Helium-rich subluminous B stars abundances

Listed in IVOA Registry (Virtual Observatory)

The connection between helium-rich hot subdwarfs of spectral types O and B (He-sdB) has been relatively unexplored since the latter were found in significant numbers in the 1980s.

Description

In order to explore this connection further, we have analysed the surface composition of six He-sdB stars, including LB 1766, LB 3229, SB 21 (= Ton-S 137 = BPS CS 29503-0009), BPS CS 22940-0009, BPS CS 29496-0010 and BPS CS 22956-0094.
