Asteroseismic Determination of sdB Stars Fundamental Parameters

Astrophysics and Space Science, 2004
Recent observational efforts and theoretical breakthroughs have encouraged the development of detailed asteroseismic analyses of rapidly oscillating sdB stars (the so-called EC14026 stars). This led to the first seismic determinations of the fundamental parameters that define the structure of EHB stars.

The Fundamental Parameters of the Central Stars of Eight WR Ring Nebulae

Space Science Reviews, 1994
We describe work that has recently been completed on deriving the fundamental parameters of eight WR stars through the photoionization modelling of their surrounding nebulae using non-LTE WR flux distributions. The resulting effective temperatures range from 57 000–71 000 K for the WN4-5 stars and
