| Abstract: |
We present sensitive radio continuum observations at 3.6 and 6 cm toward the star forming region GGD 14. The observations reveal the presence of nine extremely compact (<=0.3'') and faint radio sources in a region of 30'' around the bright cometary HII region, VLA 1. Eight of these sources show variability at radio wavelengths, and their spectral indices are characteristically negative. Four of the faint sources have an IR counterpart. We propose that gyrosynchrotron emission from an active magnetosphere explains almost all the faint compact sources, suggesting that the GGD 14 region harbors a cluster of low mass, pre-main-sequence stars. The only sources that do not show time variability are VLA 1, the cometary H II region, and VLA 7, the thermal jet in the region. |
