Spectroscopy of Pulsating sdB Stars : PG 1605 + 072 1
Received ; accepted – 2 – ABSTRACT We report the detection of velocity variations in the pulsating sdB star, PG 1605+072. Oscillations are detected at the same frequencies found from photom-etry and have amplitudes of up to 14 km s −1 for Hβ. The strongest oscillation found in previous photometric observations is not evident in our spectroscopy or photometry, and may be absent due to beating of...
متن کاملPG 1613 + 426 : a new sdB pulsator ⋆
We report the detection of short period oscillations in the hot subdwarf B (sdB) star PG 1613+426 from time-series photometry carried out with the 91-cm Cassegrain telescope of the Catania Astrophysical Observatory. This star, which is brighter than the average of the presently known sdB pulsators, with B = 14.14 mag, has T eff = 34 400 K and log g = 5.97, its position is near the hot end of th...
متن کاملPG 1618 + 563 B : A new bright pulsating sdB star ?
The results of two runs of time-series photometry made at the Nordic Optical Telescope clearly show that the sdB star PG 1618+563B is a new member of the EC 14026 class of sdB pulsators. Its power spectrum shows a doublet of frequencies at about 6.95 and 7.18 mHz (P ∼ 144 and 139 s respectively), which produce a modulation effect in the light curve with a beat period of about 1.2 hours. The amp...
متن کاملThe first PG 1159 close binary system
The archival spectrum of SDSS J212531.92-010745.9 shows not only the typical signature of a PG 1159 star, but also indicates the presence of a companion. With time-series photometry of SDSS J212531.92-010745.9 during 10 nights, spread over one month, with the Tübingen 80 cm and the Göttingen 50 cm telescopes, the binary nature of this object has recently been proven. An orbital period of 6.9 h ...
متن کاملElemental Abundances in PG 1159 Stars
The hydrogen-deficiency in extremely hot post-AGB stars of spectral class PG1159 is probably caused by a (very) late helium-shell flash or a AGB final thermal pulse that consumes the hydrogen envelope, exposing the usuallyhidden intershell region. Thus, the photospheric elemental abundances of these stars allow to draw conclusions about details of nuclear burning and mixing processes in the pre...
