OB associations in the spiral galaxy NGC 300
Listed in IVOA Registry (Virtual Observatory)
We present results of a search for OB associations in NGC 300.
Description
Using an automatic and objective method (PLC technique) 117 objects were found. Statistical tests indicate that our sample is contaminated by less than 10 detections due to random concentrations of blue stars.
Spatial distributions of detected associations and H II regions are strongly correlated. The size distribution reveals a significant peak at about 60{mu}rad which corresponds to 125 parsecs if a distance modulus of 26.66mag is assumed. Besides the objects with sizes corresponding to typical associations we also found several much larger objects.

A second level application of our detection method revealed that most of these are composed of smaller subgroups, with sizes of about 100pc.
