Expected end of optimisation phase : mid 2011

Expected accuracy ~ 1-2 m/s

Developpement of AstrAcad :

an automatic 50-cm telescope

for photometric follow-up (2012)

Goals : establish the true nature of transiting events characterize the true mass of secure planets determine central star parameters

``French’’ team involved : G. Hébrard, F. Bouchy (OHP) C. Moutou, A. Santerne (LAM)

- Close to the instrument - In charge of the observations - In charge of the upgrade & optimization of instrument- In charge of the Data Reduction Software- Close interaction with observers in case of service mode

Means to optimize SWASP-North follow-up

- Increase Nb nights (Opticon + French applications) (5.7 + 4 = 9.7 nights in 2010B)

- Large flexibilities with other Large programs CoRoT (PI: C. Moutou) SOPHIE consortium (PI: F. Bouchy) 9.7 SWASP nights spread over all the semester

- One identified RV responsible in close contact with one identified SWASP responsible for each semester

- Better coordination with other facilities (FIES and Coralie)

Proposed Schedule for 2010B

15 - 20 Oct [5 nights] 4 nights SWASP

8 - 13 Nov     [5 nights]   3.5 nights SWASP

+ 2.2 nights spread over the semester

Observers : G. Hébrard, F. Bouchy, A. Santerne, & C. Moutou

and some others SOPHIE consortium observers (service mode).
