General Description

We propose to use AMBER to measure angular diameters of red giants and
 combine them with COROT asteroseismic data which we have priviled access. The combination
 of independent techniques provides provides a mean to constraint fundamental stellar
 parameters, allowing to test stellar models. The constraints provided by the inferometric
 angular diamters are significantly better tha those currently available.

The DG has allocated 70 min to these proposal. We included 3 targets that should
 be chosen for this run, there will only be time to observe one of the targets. The
 proposal is technically very challenging, HD181907 and HD175679 are observable at
 Paranal only at the begining of the night and HD50890 at end of the night. We authorize
 any modfification of the chosen OB that may reveal to be important for meeting the
 science objective. 

Notes:

Same calibrator for HD181907 and HD175679.

HD181907 and HD50890 should be considered the prime targets.

Time-Critical Aspects

The time window for meeting the ideal observing conditions required to
 use UTs+FINITO is limited for the proposed targets. HD181907 and HD175679 are observable
 for about 3 hours after the sunset, about one hour between the twilight and airmass
 < 1.5. HD50890 is observable for about 3 hours before the sunrise rise, about
 one hour between airmass < 1.5 and the twilight.
