Description
The Carina OB1 association is one of the most massive, well-studied star-forming regions in our Galaxy, which is the kind of environment where most of the planets in our Galaxy are formed. We aim to characterize the association's stellar population as stellar clusters and high-mass stars heavily influence planets and disks. We therefore used the Gaia DR3 catalog to identify clusters and their precise position and extent, and to search for the distributed population of high-mass stars in Car OB1. We find 15 stellar groups and clusters and compile a catalog of 1374 high-mass stars, including 604 new OB candidates, in Car OB1. Extrapolating from our high-mass star catalog using the Kroupa IMF, we obtain a total number of $8\times 10^4$ stars for the entire association. We will also give a brief outlook on future disk research in Car OB1, as highly irradiated disks in the most massive cluster in Car OB1, Trumpler 14, are currently being observed with JWST as a part of the XUE collaboration.
