Time resolved spectroscopy of the multiperiodic pulsating subdwarf B star PG 1605 + 072
We present results for the 2m spectroscopic part of the Multi-Site Spectroscopic Telescope campaign, which took place in May/June 2002. In order to perform an asteroseismological analysis on the multiperiodic pulsating subdwarf B star PG 1605+072 we used over 150 hours of time resolved spec-troscopy in order to search for and analyse line profile variations by using phase binning. We succeeded ...
متن کاملGravitational settling in pulsating subdwarf B stars and their progenitors
Context. Diffusion of atoms can be important during quiescent phases of stellar evolution. Particularly in the very thin inert envelopes of subdwarf B stars, diffusive movements will considerably change the envelope structure and the surface abundances on a short timescale. Also, the subdwarfs will inherit the effects of diffusion in their direct progenitors, namely giants near the tip of the r...
متن کامل53 Persei : a slowly pulsating B star ?
A new investigation of the behaviour of the star 53 Per was performed. New photometric observations allow to confirm twodominant periods p1=2.16 d, p2= 1.67 d.A third one p3= 3.64 d is detected. These long period variations are present in our radial velocities data and in old equivalent width data. The amplitude of the p1 = 2.16 d period increases from 1977 to 1991, while the amplitude of the 1...
متن کاملsdB+WD binary with a pulsating subdwarf
The recently discovered subdwarf B (sdB) pulsator KIC 11558725 is one of the 16 pulsating sdB stars detected in the Kepler field. It features a rich g-mode frequency spectrum, with a few low-amplitude p-modes at short periods. This makes it a promising target for a seismic study aiming to constrain the internal structure of this star, and of sdB stars in general. We have obtained ground-based s...
متن کاملThe MSST Campaign : II . Effective temperature and gravity variations in the multi - periodic pulsating subdwarf B star PG 1605 + 072 ⋆ , ⋆ ⋆ , ⋆ ⋆ ⋆
Context. Stellar oscillations are an important tool to probe the interior of a star. Subdwarf B stars are core helium burning objects, but their formation is poorly understood as neither single star nor binary evolution can fully explain their observed properties. Since 1997 an increasing number of sdB stars has been found to pulsate forming two classes of stars (the V361 Hya and V1093 Her star...
