Estimated Total Execution Time (hours, including overheads)
General Description
We will employ FLAMES to observe a large sample of low-mass stars in
the pre-main sequence cluster IC 2602, in order to derive
the Li depletion boundary
(LDB) of the cluster. In total we have
selected about 200 low-mass stellar cluster members within the Li
depletion sensitive range between I=14 (LDB age of 25 Myr)
and I=16.5 (LDB age of 55 Myr).
The selected targets cover 3 FoVs of FLAMES. The remaining
fibers will all be used on candidate members of higher mass.
We will operate GIRAFFE in Medusa mode with the low resolution
grating (R~8,000), using LR06 (644.4-718.4~nm) to cover the
Li I line at 670.8 nm, H-alpha, several lines for radial
velocity measurements (for membership assessment), as well as a
variety of molecular bands for spectral-type determination, such
as e.g TiO and CaH at 651-705 nm.
The Li I line is strong in cool stars with undepleted Li,
and considering our resolution, a S/N of about 30 will be enough to
detect it when present. Part of the brightest targets will be
observed using the fiber link to UVES centred at 580 nm.
