Mission_Name: CoRoT
Description:
CoRoT, a space astronomy mission, has measured photometric micro-variability
of stars from minutes to months (up to 150 days) with a high duty cycle (more
than 90%).
The mission was led by CNES in association with four French laboratories and
7 participating countries and agencies (Austria, Belgium, Brazil, Germany,
Spain, and the ESA Science Programme).
The satellite was composed of a PROTEUS platform (the 3rd in the series) and
a unique instrument: a stellar rapid photometer. It was launched on December
27th 2006 by a Soyuz Rocket, from Baikonour.
The mission has lasted almost 6 years (the nominal 3-year duration and a
3-year extension) and has observed more than 160 000 stars.
It stopped sending data on November 2nd 2012.
Two regions of the sky were accessible for long period of time: circles of
10 degrees centered on the equator around alpha=06:50 and alpha=18:50. They
were called the CoRoT eyes: the "anticenter" and the "center eye" (as they
are approximately in these directions). Each pointing covers 1.4x2.8 square
degrees within one of those CoRoT eyes.
The original scientific objectives were focussed on the study of stellar
pulsations (asteroseismology) to probe the internal structure of stars, and
the detection of small exoplanets through their "transit" in front of their
host star, and the measurement of their size.
This lead to introduce two modes of observations, working simultaneously:
- The "bright star" mode dedicated to very precise seismology of a small
sample of bright and closeby stars
- The "faint star" mode, observing a very large number of stars at the
same time, to detect transits, which are rare events, as they imply
the alignment of the star, the planet and the observer. The large
amount of data gathered in this mode turned out to be extremely
fruitful for many topics of stellar physics.
Beyond these two initial objectives, CoRoT data revealed stellar variability
associated with various other phenomena: granulation, rotational modulation
by spots associated with magnetic activity, oblateness induced by a nearby
companion star, ...
The data of this CoRoT CDS archive correspond to the legacy release V4.4 of
CoRoT N2 data. A complete description can be found in the
"CoRoTN2versions_30sept2014.pdf" document available on the vizier ftp as well
as on project websites listed in the "See also" field below.

- archive at https://sipad-corot.cnes.fr/ or at the CoRoT IAS archive,
but they require a deep understanding of the instrument and the
observation conditions to be scientifically helpful.
