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…
Dissolving star cluster candidates
E. Bica, B. X. Santiago, C. M. Dutra +3
We present a list of 34 neglected entries from star cluster catalogues located at relatively high galactic latitudes ( 15) which appear to be candidate late stages…
Morphologies and ages of star cluster pairs and multiplets in the Small Magellanic Cloud
M. R. de Oliveira, C. M. Dutra, E. Bica +1
An isophotal atlas of 75 star cluster pairs and multiplets in the Small Magellanic Cloud is presented, comprising 176 objects. They are concentrated in the SMC main body. The isoph…
Final Stages of N-body Star Cluster Encounters
M. R. de Oliveira, E. Bica, H. Dottori
We performed numerical simulations of star cluster encounters with Hernquist's TREECODE in a CRAY YMP-2E computer. We used different initial conditions (relative positions and velo…
