A near-infrared study of IRAS-selected T Tauri stars in Chamaeleon II.

Abstract (from CDS):

We use near-infrared photometry of objects detected by IRAS to confirm four new T Tauri stars in Chamaeleon II. Observations of these sources generally agree with the T Tauri signatures of locus in the near-infrared color-color diagram, mid-infrared spectral index, and IRAS far-infrared colors. Infrared properties of these stars are similar to optically selected T Tauri stars in Cha II, but are on average more luminous and are located at the north-east boundary of star formation in the cloud. We compare results of infrared color methods used to detect T Tauri stars in Cha II with results of other methods based on optical and X-ray emission.
