IR photometry in the {gamma} Vel cluster
Listed in IVOA Registry (Virtual Observatory)
We present new Spitzer Space Telescope observations of stars in the young (~5Myr) {gamma} Velorum stellar cluster.
Description
Combining optical and 2MASS photometry, we have selected 579 stars as candidate members of the cluster. With the addition of the Spitzer mid-infrared data, we have identified five debris disks around A-type stars and five to six debris disks around solar-type stars, indicating that the strong radiation field in the cluster does not completely suppress the production of planetesimals in the disks of cluster members.
However, we find some evidence that the frequency of circumstellar primordial disks is lower, and the infrared flux excesses are smaller than for disks around stellar populations with similar ages.
