  3. TEIDE OBSERVATORY.- TENERIFE ISLAND First astrophysical studies (1964) Altitude: 2400 m • Solar telescopes: • VTT (70 cm) • Themis (90 cm) • Gregor (1.5 m) • Solar laboratory • Night telescopes: • Mons (50 cm) • IAC80 (80cm) • Carlos Sánchez (TCS, 1.55 m) • Big field OGS (1 m) • Stare (10 cm) www.iac.es/ot/indice.html

  4. ROQUE DE LOS MUCHACHOS OBSERVATORY.- LA PALMA ISLAND Inaugurated in 1985 Altitude: 2400 m • Solar telescopes • Swedish Solar Telescope (1 m) • DOT (45 cm) • Night telescopes: • CMT (18 cm) • Isaac Newton Group of Tescopes • William Herschel (4.2 m) • JKT (1 m) • Isaac Newton (ING, 2.5 m) • NOT (2.5 m) • Galileo (TNG, 3.5 m) • Mercator (1.2 m) • Liverpool (2 m) www.iac.es/gabinete/orm/indice.html

  9. My news from the Canary Islands… Trying a PhD

  10. Participation in space mission SOHO Helioseismic observations Participation in helioseismic networks Participation in space mission COROT Participation in STEPHI network Study of Delta Scuti stars, hot subdwarfs Participation in space mission COROT Participation in STARE IAC Group on Solar and Stellar Seismology and Exoplanet Searches Helioseismology Asteroseismology Extrasolar planets P.I. Teodoro Roca Cortés Pere Pallé Antonio Jiménez Clara Régulo Fernando Pérez Juan A. Belmonte Sebastián Jiménez Hans Deeg Lexter Fox (just PhD finished) Francisco Espinosa (just PhD finished) Roi Alonso (PhD student) Héctor Vázquez (PhD student) Rosa M. Domínguez (PhD student) Raquel Oreiro (PhD student)

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

  12. - 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

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

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