Photometric and Kinematic Studies of Open Star Clusters I: NGC 581 (M 103)
Joerg Sanner, Michael Geffert, Jens Brunzendorf +1
We present CCD photometry and a proper motion study of the young open star cluster, NGC 581 (M 103). Fitting isochrones to the colour magnitude diagram, we found an age of 16 +/- 4…
The ROSAT deep survey: V. X-rays Sources and Optical Identifications in the Marano Field
G. Zamorani, M. Mignoli, G. Hasinger +7
We present the X-ray data and the optical identifications for a deep ROSAT PSPC observation in the "Marano field". In the inner region of the ROSAT field (15' radius) we detected 5…
Very young massive stars in the Small Magellanic Cloud, revealed by HST
M. Heydari-Malayeri, M. R. Rosa, H. Zinnecker +2
High spatial resolution imaging with the Hubble Space Telescope allowed us to resolve the compact HII, region N81 lying in the Small Magellanic Cloud (SMC). We show the presence of…
