Near - and Far - Infrared Counterparts of Millimeter Dust Cores in the Vela Molecular Ridge Cloud D ⋆
Aims. Identify the young protostellar counterparts associated to dust millimeter cores of the Vela Molecular Ridge Cloud D through new IR observations (H2 narrow-band at 2.12 μm and N broad band at 10.4 μm) along with an investigation performed on the existing IR catalogues. Methods. The association of mm continuum emission with infrared sources from catalogues (IRAS, MSX, 2MASS), JHK data from...
متن کاملStar formation in the Vela Molecular Ridge Large scale mapping of cloud D in the mm continuum ⋆
Context. The Vela Molecular Ridge is one of the nearest intermediate-mass star forming regions, located within the galactic plane and outside the solar circle. Cloud D, in particular, hosts a number of small embedded young clusters. Aims. We present the results of a large-scale map in the dust continuum at 1.2 mm of a ∼ 1 • × 1 • area within cloud D. The main aim of the observations was to obta...
متن کاملar X iv : a st ro - p h / 06 10 08 3 v 1 3 O ct 2 00 6 Mapping molecular emission in Vela Molecular Ridge Cloud D
We present the CO(1-0) and CO(2-1) line maps obtained observing with the SEST a ∼ 1 × 1 region of the Vela Molecular Ridge, Cloud D. This cloud is part of an intermediate-mass star forming region that is relatively close to the Sun. Our observations reveal, over a wide range of spatial scales (from ∼ 0.1 to a few parsecs), a variety of dense structures such as arcs, filaments and clumps, that a...
متن کاملTesting circumstellar disk lifetimes in young embedded clusters associated with the Vela Molecular Ridge*
Context. The Vela Molecular Ridge hosts a number of young embedded star clusters at the same evolutionary stage. Aims. We test whether the fraction of members with a circumstellar disk in a sample of clusters in the cloud D of the Vela Molecular Ridge, is consistent with relations derived for larger samples of star clusters with an age spread. In addition, we constrain the age of the young embe...
متن کاملDeep Near Infrared Imaging toward Vela Molecular Ridge C - 1 : A Remarkable Embedded Cluster in RCW
We present deep near-infrared (J, H, K S) images toward an embedded cluster which lies in a C 18 O clump in the cloud C of the Vela Molecular Ridge. This cluster has at least ∼ 350 members and a radius of ∼ 0.5 pc. The stellar surface number density is approximately 3000 stars pc −2 in the central 0.1 pc × 0.1 pc region of the cluster. This is much higher than most of the young clusters within ...
