Maser emission in Regions of Star Formation in High Mass: Disk Tracers or "Jets"?

Abstract

A previous study this one, with which it was intended to determine whether masers of methanol , hydroxyl and water align in a significant number of the regions most frequently with disk structures or "jets" that accompany the process of formation of high-mass stars. The results of this study indicate that emissions of masers around the proto-stars of high mass tend to form groups at a very high percentage distributions are linear or elongated. The linearity of the distributions of the masers is so frequent that it is consistent with the idea that the masers are linked or occur in the discs or jets. However we did not find a significant preference of the masers of methanol, hydroxyl and water to align with disks and jets. This contribution presents the results of 8 new regions, we find that past performance is maintained, meaning that the masers are aligned with disks and jets in similar proportions.
