ASTEROSEISMOLOGY.- HOT B SUBDWARFS (sdBs)
What are hot B subdwarfs?
blue colors, low luminosity
evolutionary state: after FGB – before WD cooling track
uncertainties: mass, formation channels, spectral unhomogenity
Pulsations in hot B subdwarfs
EC14026 stars = V361 Hya:
1997 theoretical – observational discovery
short period oscillators
Betsy stars = PG1716
2002
long period oscillators
