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:                   Betsy stars = PG1716

 1997 theoretical – observational discovery                  2002
          short period oscillators                  long period oscillators
