Description
Evolutionary tracks are of key importance for the understanding of star
formation. Unfortunately, tracks published by various groups differ so
that it is fundamental to have observational tests. In order to do this,
we intend to measure the masses of the two components of the Pre-Main
Sequence (PMS) binary HD113449 by combining radial velocity (RV)
measurements taken with HARPS, with infrared interferometric data using
AMBER on the VLTI. The spectroscopic orbit that has already been
determined, combined with the first AMBER measurement, allows us to
obtain a very first estimation of the inclination of the binary system
and from this the masses of the two stars. More AMBER measurements of HD
113449 are needed to improve the precision on the masses: in the ESO
period P82 two new measurements are scheduled.
