VLA observations of the (1, 1) inversion transition of NH3 in seven regions with high-velocity gaseous outflows is presented. Small condensations (less than about 0.1 pc) were detected in L1551, S140, and Cepheus A. The condensation in L1551 is displaced by approximately 28 arcsec from IRS 5, the suspected source of energy of the region, while that observed in S140 seems to be the core of the more extended NH3 source observed with a single dish. Three individual condensations were detected in Cepheus A, one of them with a remarkably elongated shape. These condensations may play an important role in focusing the bipolar outflow in the region. A comparison of the VLA ammonia and continuum maps suggests that many of the continuum knots seen in Cepheus A may be bright rims excited by two central stars.
