Asteroseismic Investigation of Known Planet Hosts in the Kepler Field
J. Christensen-Dalsgaard, H. Kjeldsen, T. M. Brown +7
In addition to its great potential for characterizing extra-solar planetary systems the Kepler mission is providing unique data on stellar oscillations. A key aspect of Kepler aste…
Open issues in stellar modelling
J. Christensen-Dalsgaard
An important goal of helio- and asteroseismology is to improve the modelling of stellar evolution. Here I provide a brief discussion of some of the uncertain issues in stellar mode…
Sounding stellar cycles with Kepler - preliminary results from ground-based chromospheric activity measurements
C. Karoff, T. S. Metcalfe, W. J. Chaplin +6
Due to its unique long-term coverage and high photometric precision, observations from the Kepler asteroseismic investigation will provide us with the possibility to sound stellar…
The Stellar Observations Network Group - the Prototype
F. Grundahl, J. Christensen-Dalsgaard, H. Kjeldsen +4
The Stellar Observations Network Group (SONG) has obtained full funding for the design, construction and implementation of a prototype telescope and instrumentation package for the…
A note on the torsional oscillation at solar minimum
R. Howe, J. Christensen-Dalsgaard, F. Hill +3
We examine the evolution of the zonal flow pattern in the upper solar convection zone during the current extended solar minimum, and compare it with that during the previous minimu…
A Stellar Model-fitting Pipeline for Asteroseismic Data from the Kepler Mission
T. S. Metcalfe, O. L. Creevey, J. Christensen-Dalsgaard
Over the past two decades, helioseismology has revolutionized our understanding of the interior structure and dynamics of the Sun. Asteroseismology will soon place this knowledge i…
