ASTEROSEISMOLOGY. - HOT B SUBDWARFS (sd. Bs) 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 EC 14026 stars = V 361 Hya: Betsy stars = PG 1716 1997 theoretical – observational discovery 2002 short period oscillators long period oscillators

ASTEROSEISMOLOGY. - HOT B SUBDWARFS (sd. Bs) My Ph. D project. - Observational part - IAC 80 telescope (Tenerife) 80 cm, V~15 Instruments: • TTP (4 ch photometer) • TCP (CCD in windowed mode) -NOT (La Palma) 2. 5 m , V~17 Instrument: • ALFOSC (windowed fast photometry mode)

ASTEROSEISMOLOGY. - HOT B SUBDWARFS (sd. Bs) My Ph. D project. - Observational part Precise characterization of known sd. B pulsators seismological study Search for new sd. B pulsators one new sd. B pulsator: Balloon 090100001 brightest short period oscillator highest amplitude oscillation

ASTEROSEISMOLOGY. - HOT B SUBDWARFS (sd. Bs) My Ph. D project. - Observational part short and long period oscillations many frequencies

ASTEROSEISMOLOGY. - HOT B SUBDWARFS (sd. Bs) My Ph. D project. - Observational part Andrzej + Raquel data

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