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…
On Flare Driven Global Waves
C. Karoff
We recently presented evidence of a strong correlation between the energy in the high-frequency part of the acoustic spectrum of the Sun and the solar X-ray flux Karoff & Kjeldsen…
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…
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…
High-frequency modes in solar-like stars
C. Karoff
p-mode oscillations in solar-like stars are excited by the outer convection zone in these stars and reflected close to the surface. The p-modes are trapped inside an acoustic cavit…
