Deep 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 ...
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 کاملNear - 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 کاملResolving the food security problem with an interdisciplinary approach
Food is one of the basic human needsand providing it is directly related to food security. The concept of food security in its historical process has been debated from various aspects of physical and economical access to healthy and nutritious food at all times. Food insecurity is considered a complex policy problem with different aspects. This problem requires a network of communication among ...
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...
