A 3 µm survey of the Chamaeleon I dark cloud.

KENYON S.J. and GOMEZ M.

Abstract (from CDS):

We describe an L-band photometric survey of ∼ 0.5 deg2 of the Chamaeleon I dark cloud. The survey has a completeness limit of L<11.0. Our survey detects 124 sources, including all known pre-main-sequence stars with L≤11. The fraction of sources with near-IR excess emission is 58%±4% for K=9-11. Cha I sources have bluer H-K and K-L colors than pre-main-sequence stars in Taurus-Auriga. These sources also have a strong correlation between EW(Hα) and K-L. Stars with K-L≤0.6 have weak Hα emission; stars with K-L≥0.6 have strong Hα emission. Because many Cha I sources are heavily reddened, this division between weak emission T Tauri stars and classical T Tauri stars occurs at a redder K-L than in Taurus-Auriga.
