Star clusterings in the Carina complex: UBVRI photometry of Bochum 9, 10 and 11.


Abstract (from CDS):

We report on the first UBVRI CCD photometry of three poorly known star clusterings in the region of η Carinae: Bochum 9, 10 and 11. We find that they are young, rather poor, loose open clusters.

We argue that Bochum 9 is probably a small and loose open cluster with about 30 probable members having E(B-V)=0.63±0.08, located 4.6kpc far from the Sun, beyond the Carina spiral arm.

Similarly, Bochum 10 is a sparse aggregate with 14 probable members having E(B-V)=0.47±0.05 and at a distance of 2.7kpc from the Sun.

Finally, Bochum 11 is a less than 4x106yr old cluster for which we identify 24 members. It has a reddening E(B-V)=0.58±0.05, and lies between Bochum 10 and 9, at 3.5kpc from the Sun. We propose that in the field of the cluster some stars might be pre-main-sequence candidates.
