| Abstract: |
After more than 4 years in orbit CoRoT has observed about 130 bright stars (in the so-called seismology field)
spanning a large part of the Hertzsprung-Russell (H-R) diagram,
and more than 130 000 fainter ones (in the so-called exoplanet field) with a lower signal to noise ratio and time sampling.
Time-series cover up to 160 days with a duty cycle larger than 90%. The data are photon noise limited over most of the magnitude range.
These observations are continuing, since the mission has been extended for several years.
The quality of the data meets the specifications and the seismic parameters are accessed at the precision necessary for interpretation.
CoRoT has discovered very diverse and new structures and founded the field of
“Time Domain Stellar Astrophysics”.
It has shown the way for more advanced and detailed analyses; some of these were expected for a long time,
others are completely new.
Beyond this technical and observational success,
a few examples show how these data have already addressed some of the open questions
in stellar structure and evolution, though definite conclusions will need cross-comparisons of results on a larger set of stars; CoRoT and Kepler will continue to extend the sample. |
