A QSO survey via optical variability and zero proper motion in the M92 field. IV. More QSOs due to improved photometry
J. Brunzendorf, H. Meusinger
We continue the QSO search in the 10 square degrees Schmidt field around M92 based on variability and proper motion (VPM) constraints. We have re-reduced 162 digitised B plates wit…
A QSO survey via optical variability and zero proper motion in the M92 field.III. Narrow emission line galaxies
H. Meusinger, J. Brunzendorf
We study a sample of 23 narrow-emission line galaxies (NELGs) which were selected by their strong variability as QSO candidates in the framework of a variability-and-proper motion…
Photometric and kinematic studies of open star clusters. III. NGC 4103, NGC 5281, and NGC 4755
Joerg Sanner, Jens Brunzendorf, Jean-Marie Will +1
We present CCD photometry and proper motion studies of the three open star clusters NGC 4103, NGC 5281, and NGC 4755 (kappa Cru). By fitting isochrones to the colour magnitude diag…
Photometric and kinematic studies of open star clusters. II. NGC 1960 (M 36) and NGC 2194
Joerg Sanner, Martin Altmann, Jens Brunzendorf +1
We present CCD photometry and proper motion studies of the two open star clusters NGC 1960 (M 36) and NGC 2194. Fitting isochrones to the colour magnitude diagrams, for NGC 1960 we…
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…
