The young population of the Chamaeleon II dark cloud
Loredana Spezzi, Juan M. Alcala', Elvira Covino +9
We discuss the results of the optical spectroscopic follow-up of pre-main sequence (PMS) objects and candidates selected in the Chamaeleon II dark cloud based on data from the Spit…
The Spitzer c2d Survey of Large, Nearby, Interstellar Clouds.X. The Chamaeleon II Pre-Main Sequence Population as Observed With IRAC and MIPS
Juan M. Alcala', Loredana Spezzi, Nicholas Chapman +9
We discuss the results from the combined IRAC and MIPS c2d Spitzer Legacy survey observations and complementary optical and near infrared data of the Chamaeleon II (Cha II) dark cl…
Spatial separation of small and large grains in the transitional disk around the young star IRS 48
V. C. Geers, K. M. Pontoppidan, E. F. van Dishoeck +5
We present spatially resolved mid-infrared images of the disk surrounding the young star IRS 48 in the Ophiuchus cloud complex. The disk exhibits a ring-like structure at 18.7 micr…
The Metallicity of Post-T Tauri Stars: A preliminary approach to the understanding of the metal enrichment of stars harboring planets
Ramiro de la Reza, Licio da Silva, Roberta Almeida +3
The metallicity of young low mass Post-T Tauri stars in coeval associations is practically unknown. This work is the beginning of a systematic measurement of these metallicities ba…
