(Stellar)Activity
Rotation
After LoI and 1sr Corot Brasil meeting, a need
for people with similar scientific interest to
gather and organize particularly many interests
in getting Corot data to study rotation and
stellar activity AOJuly 05 Selection (Sept 05)
over 45 proposals, 28 accepted out of which
10 at least concern AcRoCorot

Questions such as (poster 6 Del Peloso) What
physical processes control the behavior of
rotation during stellar evolution from PMS to
PostMS Giants? How does magnetic breaking affect
rotation ? What physical processes control the
generation of magnetic field? What type(s) of
dynamo is at play in stellar interiors? Do we
correctly understand and model surface structures
such as spots and stellar granulation ? What
is the exact nature of the interplay between
rotation, convection and activity ?
4
AcRoCorot objectives be ready when data come
to use them efficiently hence organisation of
meetings such as the present one to motivate -
teams with similar interest to continue to meet
and talk (collaboration, exchange of brain
thinkings and tools) - teams with accepted
proposal to work it out in more details
feasibility (observational requirements-
adopted techniques) lists of target stars
