New infrared star clusters in the Northern and Equatorial Milky Way with 2MASS
Abstract
We carried out a survey of infrared star clusters and stellar groups on the 2MASS J, H and Ks all-sky release Atlas in the Northern and Equatorial Milky Way (350deg < l < 360 deg, 0deg < l < 230 deg). The search in this zone complements that in the Southern Milky Way (Dutra et al. \cite{Dutra03}a). The method concentrates efforts on the directions of known optical and radio nebulae. The present study provides 167 new infrared clusters, stellar groups and candidates. Combining the two studies for the whole Milky Way, 346 infrared clusters, stellar groups and candidates were discovered, whereas 315 objects were previously known. They constitute an important new sample for future detailed studies.
