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
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:
