A multi-site campaign to measure solar-like oscillations in Procyon. I. Observations, Data Reduction and Slow Variations
Torben Arentoft, Hans Kjeldsen, Timothy R. Bedding +45
We have carried out a multi-site campaign to measure oscillations in the F5 star Procyon A. We obtained high-precision velocity observations over more than three weeks with eleven…
The amplitude of solar oscillations using stellar techniques
Hans Kjeldsen, Timothy R. Bedding, Torben Arentoft +6
The amplitudes of solar-like oscillations depend on the excitation and damping, both of which are controlled by convection. Comparing observations with theory should therefore impr…
Evidence that solar flares drive global oscillations in the Sun
C. Karoff, H. Kjeldsen
Solar flares are large explosions on the Sun's surface caused by a sudden release of magnetic energy. They are known to cause local short-lived oscillations travelling away from th…
Massive stars exploding in a He-rich circumstellar medium. I. Type Ibn (SN 2006jc-like) events
A. Pastorello, S. Mattila, L. Zampieri +26
We present new spectroscopic and photometric data of the type Ibn supernovae 2006jc, 2000er and 2002ao. We discuss the general properties of this recently proposed supernova family…
Oscillations in Procyon A: First results from a multi-site campaign
S. Hekker, T. Arentoft, H. Kjeldsen +45
Procyon A is a bright F5IV star in a binary system. Although the distance, mass and angular diameter of this star are all known with high precision, the exact evolutionary state is…
Stellar Oscillations Network Group
F. Grundahl, H. Kjeldsen, J. Christensen-Dalsgaard +2
Stellar Oscillations Network Group (SONG) is an initiative aimed at designing and building a network of 1m-class telescopes dedicated to asteroseismology and planet hunting. SONG w…
