The scientific Programme

The scientific Programme
where are we ?
Less than one year from launch !
2
The selection of the region of the sky
Seismology and exoplanet constraints
Priorities among the possible fields Several
iterations..
3
The drift of the orbit
How to reduce the distance to the centre of the
observable zone To decrease perturbations due to
straylight Implies a chronology

The general planning
Core Programme

• 2 first long runs CW8/SC14
• LRa1 a101.7 d - 0.19 r 7.3
• LRc1 a290.9 d 0.48 r 19 (tbc)

- Choice of the short run of the anticentre SRa1
CW9/SC16 - Next long runs LRa2, LRc2
CW10/SC?

Seismology exploratory programme
Half of the short runs are dedicated to the
seismology exploratory programme 3 minimum
Initial objective coverage of the HR diagram
But..the job will be done by the long runs
12
The first  seismology  short run
As simple as possible to observe -in a region
covered by EXODAT, not too crowded - at
least one 6th magnitude star in the seismology
field First class scientific results rapidly?
Define the scientific cases not reached in the
central programme Choice of 4 possible short
runs 2 in each direction Priorities special
attention to the first one Planning 1 in each
direction at CW9 ? AP first short runsee
