Lithium and rotation on the subgiant branch. I. Observations and spectral analysis.

LEBRE A., DE LAVERNY P., DE MEDEIROS J.R., CHARBONNEL C. and DA SILVA L.

Abstract (from CDS):

We have obtained new high resolution spectroscopic observations of the lithium line at 6707.81Å and derived lithium abundances (ALi) by spectral synthesis for a sample of about 120 F-, G- and K-type Population I subgiant stars. For each of these stars, high precision rotational velocity obtained with the CORAVEL spectrometer is available. We present the behavior of the lithium abundance as a function of effective temperature, which shows a sort of discontinuity around 5600K, somewhat later than the well known rotational discontinuity.
