A Search for Environmental Influence on Stellar Mass

The positions and local projected densities of the protostellar continuum sources in Ophiuchus and Serpens are investigated as a function of their masses in order to search for possible environmental e †ects during star formation. There is a slight trend toward mass segregation for the 850 km sources found by Johnstone and coworkers in Ophiuchus, but there is no obvious mass segregation for the 1.3 mm sources in Ophiuchus or Serpens. There is also no systematic change in the local projected
