Lithium in young solar-type stars in the Orion Nebula region.
DUNCAN D.K. and REBULL L.M.
Abstract (from CDS):
The status of Parenago 1799 as an ultra-fast fotator (UFR) (Walker 1990) is qualitatively confirmed; it is shown that the star is rotating at an appreciable fraction of breakup velocity. This is the only UFR in the present sample, fewer than in a Pleiades sample of similar size.
The two T Tauri stars in the binary system Parenago 1540 have similar lithium abundances, suggesting similar depletion histories, and consistent with the findings of Lee, et al. (1994).
Parenago 1643 and 1929 are shown to have incorrect apparent colors via newly-determined spectral types; their observed colors lead to very high Li abundances, but their corrected colors suggest more typical lithium abundances. Similarly, we have used spectra types and the spectral type-color relation from Duncan (1993) to refine teh colors and thus improve our estimates of Li abundances for P1477 and P1518.
