Source I in the Orion BN/KL region is the nearest example of a
high-mass young stellar object (YSO), and one of the few star-forming
sources known to power both H2O and SiO masers. These masers
enable mapping of the structure and dynamical evolution of material
within 10 - 1000 AU of a high-mass YSO in unprecedented detail (~0.1 AU
resolution), and provide strong evidence for a compact disk and
outflow. In this poster, we present examples of the dataset that we
have used to inform preliminary geometric and dynamical models of
Source I. We show a comparison of simple models aimed at establishing
the YSO geometry that include treatments of maser (un)saturation, and
varying density and velocity fields. Finally, we discuss the
implications of our results for high-mass star formation in general. |
