A photometric study of the young open cluster NGC 1220
S. Ortolani, G. Carraro, S. Covino +2
We present UBV CCD observations obtained in the field of the northern open cluster NGC 1220, for which little information is available. We provide also BV CCD photometry of a field…
NGC 1912 and NGC 1907: a close encounter between open clusters ?
M. R. de Oliveira, A. Fausti, E. Bica +1
The possible physical relation between the closely projected open clusters NGC 1912 (M 38) and NGC 1907 is investigated. Previous studies suggested a physical pair based on similar…
Low-extinction windows in the inner Galactic Bulge
C. M. Dutra, B. X. Santiago, E. L. D. Bica
We built K band extinction maps in the area of two candidate low-extinction windows in the inner Bulge: W0.2-2.1 at (l,b) = (0.25o,-2.15o), and W359.4-3.1 at (l,b) = (359.40o,-3.10…
HST NICMOS Photometry of the reddened bulge globular clusters NGC 6528, Terzan 5, Liller 1, UKS 1 and Terzan 4
S. Ortolani, B. Barbuy, E. Bica +4
We present results from NICMOS Hubble Space Telescope observations of the reddened bulge globular clusters NGC 6528, Terzan 5, Liller 1, UKS 1 and Terzan 4, obtained through the fi…
New infrared star clusters and candidates in the Galaxy detected with 2MASS
C. M. Dutra, E. Bica
A sample of 42 new infrared star clusters, stellar groups and candidates was found throughout the Galaxy in the 2MASS J, H and especially K Atlases. In the Cygnus X region 19 n…
Open clusters or their remnants: B and V photometry of NGC 1901 and NGC 1252
D. B. Pavani, E. Bica, C. M. Dutra +4
Photometry in the B and V bands is presented for the southern stellar groups NGC 1901 and NGC 1252. NGC 1901 is often described as an open cluster while NGC 1252 consists of a conc…
