Solar-like oscillations in the G8 V star tau Ceti
T. C. Teixeira, H. Kjeldsen, T. R. Bedding +8
We used HARPS to measure oscillations in the low-mass star tau Cet. Although the data were compromised by instrumental noise, we have been able to extract the main features of the…
Massive B-type pulsators in low-metallicity environments
C. Karoff, T. Arentoft, L. Glowienka +5
Massive B type pulsators such as beta Cep and slowly pulsating B (SPB) stars pulsate due to layers of increased opacity caused by partial ionization. The increased opacity blocks t…
Measurements of Stellar Properties through Asteroseismology: A Tool for Planet Transit Studies
Hans Kjeldsen, Timothy R. Bedding, Joergen Christensen-Dalsgaard
Oscillations occur in stars of most masses and essentially all stages of evolution. Asteroseismology is the study of the frequencies and other properties of stellar oscillations, f…
AsteroFLAG: first results from hare-and-hounds Exercise 1
W. J. Chaplin, T. Appourchaux, T. Arentoft +15
We report on initial results from the first phase of Exercise 1 of the asteroFLAG hare and hounds. The asteroFLAG group is helping to prepare for the asteroseismology component of…
SPB stars in the open SMC cluster NGC 371
C. Karoff, T. Arentoft, L. Glowienka +5
Pulsation in beta Cep and SPB stars are driven by the kappa mechanism which depends critically on the metallicity. It has therefore been suggested that beta Cep and SPB stars shoul…
Observing solar-like oscillations
Timothy R. Bedding, Hans Kjeldsen
The past few years have seen great progress in observing oscillations in solar-type stars, lying on or just above the main sequence. We review the most recent results, most of whic…
