Abstract:
The high angular resolution images with the Very Large Array (VLA)
allow us to explore the general properties of protostellar cores in
massive star forming regions at large distances.
We observed the NH3 (J, K)=(1, 1) and (2, 2) lines toward five massive
protostar candidates (IRAS 18196-1331, IRAS 18352-0148,
IRAS 18361-0627, IRAS 18414-0339 and IRAS 19474+2637) with the VLA D
configuration.
