A newly discovered open cluster surrounding the Wolf-Rayet stars WR 38 and WR 38a.


Abstract (from CDS):

Photoelectric and CCD UBV survey data are presented for stars brighter than about V∼16.5 in the field of the faint Carina Wolf-Rayet (WR) stars WR 38 and WR 38a. Both WR stars appear to belong to an associated compact cluster (nuclear diameter ∼0'.3) of at least six faint OB stars reddened by EB–V=1.60±0.02 s.e. and lying at a distance of ∼14.5±1.6 kpc (V0-MV=15.80±0.25 s.d.). As cluster members, the two WR stars have estimated luminosities of Mv=-5.8 (WR 38, type WC4) and Mv=-5.0 (WR 38a, type WN5). The former value is slightly more luminous than expected for Galactic WR stars.
