Using the Very Long Baseline Array (VLBA), we have observed the radio continuum emission from the young stellar object HW 9 in the Cepheus A star-forming region at 10 epochs between 2007 February and 2009 November. Due to its strong radio variability, the source was detected at only four of the ten epochs. From these observations, the trigonometric parallax of HW 9 was determined to be {pi} = 1.43 {+-} 0.07 mas, in excellent agreement with a recent independent determination by Moscadelli et al… CONTINUE READING
