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 = PG long period oscillators

ASTEROSEISMOLOGY.- HOT B SUBDWARFS (sdBs) My PhD project.- Observational part - IAC80 telescope (Tenerife) 80cm, V~15 Instruments: TTP (4ch photometer) TCP (CCD in windowed mode) -NOT (La Palma) 2.5 m, V~17 Instrument: ALFOSC (windowed fast photometry mode)

ASTEROSEISMOLOGY.- HOT B SUBDWARFS (sdBs) My PhD project.- Observational part Precise characterization of known sdB pulsators seismological study Search for new sdB pulsators one new sdB pulsator: Balloon brightest short period oscillator highest amplitude oscillation

My PhD project.- Observational part ASTEROSEISMOLOGY.- HOT B SUBDWARFS (sdBs) short and long period oscillations many frequencies

My PhD project.- Observational part ASTEROSEISMOLOGY.- HOT B SUBDWARFS (sdBs) Andrzej + Raquel data

Future work: 2005 Balloon campaign ASTEROSEISMOLOGY.- HOT B SUBDWARFS (sdBs)
