A VLA search for compact radio sources in the explosive molecular outflows DR 21 and G5.89
Vanessa Yanza, Sergio A. Dzib, Aina Palau +3
We present high-angular-resolution () VLA Ku-band (12--18 GHz) observations of two explosive molecular outflows (EMOs), DR 21 and G5.89, in a search for runaway s…

The Radio Continuum Source Projected Near HR 8799
Luis F. Rodriguez, Luis A. Zapata
HR 8799 is an A5/F0 V star where exoplanets were first directly imaged. Four exoplanets were found within from the star. Here we report the VLA detection of a…
