The Spitzer c2d legacy results: star-formation rates and efficiencies; evolution and lifetimes
The c2d Spitzer Legacy project obtained images and photometry with both IRAC and MIPS instruments for five large, nearby molecular clouds. Three of the clouds were also mapped in dust continuumExpand

X-shooter spectroscopy of young stellar objects: I - Mass accretion rates of low-mass T Tauri stars in \sigma Orionis
We present high-quality, medium resolution X-shooter/VLT spectra in the range 300-2500 nm for a sample of 12 very low-mass stars in the Orionis cluster. The sample includes eight stars with evidenceExpand

Pre-main sequence spectroscopic binaries suitable for VLTI observations ,
Context. A severe problem for research in star-formation is that the masses of young stars are almost always estimated from evolutionary tracks alone. Since the tracks published by different groupsExpand

X-shooter spectroscopy of young stellar objects in Lupus. Accretion properties of class II and transitional objects
The mass accretion rate, Ṁ acc , is a key quantity for the understanding of the physical processes governing the evolution of accretion discs around young low-mass ( M ⋆  ≲ 2.0 M ⊙ ) stars andExpand

Search for young stars among ROSAT All-Sky Survey X-ray sources in and around the R CrA dark cloud ⋆
We present the ROSAT All-Sky Survey data in a 126 deg 2 area in and around the CrA star forming region. With low-resolution spectroscopy of unidentied ROSAT sources we could nd 19 new pre-mainExpand

On the pre-main sequence circularization period
In this paper we present an updated compilation of the currently known pre-main sequence (PMS) spectroscopic binaries (SB) for which orbital elements have been determined. In particular we report ourExpand

Improved fundamental parameters for the low-mass pre-main sequence eclipsing system RX J0529.4+0041
We report new photometric observations and a new determination of the fundamental stellar parameters for the low-mass pre-main sequence eclipsing system RX J0529.4+0041A based on high-precision,Expand

High resolution spectroscopy of ROSAT discovered weak line T Tauri stars near Lupus
We present high-resolution optical echelle spectroscopy for a large fraction of the Li-rich late-type stars recently discovered in the vicinity of the Lupus dark clouds. Our results confirm the highExpand

The Young Population of the Chamaeleon II Dark Cloud
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 Spitzer Legacy surveyExpand
