SMA Submillimeter Observations of HL Tau: Revealing a compact molecular outflow

Abstract

We present archival high angular resolution ($\sim$ 2${}^{\prime \prime }$) ${}^{12}$CO(3-2) line and continuum submillimeter observations of the young stellar object HL Tau made with the Submillimeter Array (SMA). The ${}^{12}$CO(3-2) line observations reveal the presence of a compact and wide opening angle bipolar outflow with a northeast and southwest orientation (P.A. = 50${}^{\circ }$), and that is associated with the optical and infrared jet emanating from HL Tau with a similar orientation. On the other hand, the 850 $\mu$m continuum emission observations exhibit a strong and compact source in the position of HL Tau that has a spatial size of $\sim$ 200 $\times$ 70 AU with a P.A. $=$ 145${}^{\circ }$, and a dust mass of around 0.1 M${}_{\odot }$. These physical parameters are in agreement with values obtained recently from millimeter observations. This submillimeter source is therefore related with the disk surrounding HL Tau.
