A multiwavelength study of massive star-forming region IRAS 22506+5944

TL;DR

This study investigates the complex star formation processes in IRAS 22506+5944 through multi-line observations, revealing two cores at different stages, a new methanol maser, and an energetic bipolar outflow.

Contribution

It provides new insights into the physical conditions and evolutionary stages of cores in a massive star-forming region using multiwavelength data and molecular line observations.

Findings

Detection of a new 6.7 GHz methanol maser.

Identification of two cores with different masses and evolutionary stages.

Observation of a bipolar outflow with significant mass.

Abstract

We present a multi-line study of the massive star-forming region IRAS 22506+5944. A new 6.7 GHz methanol maser was detected. 12CO, 13CO, C18O and HCO+ J = 1-0 transition observations reveal a star formation complex consisting mainly of two cores. The dominant core has a mass of more than 200 solar mass, while another one only about 35 solar mass. Both cores are obviously at different evolutionary stages. A 12CO energetic bipolar outflow was detected with an outflow mass of about 15 solar mass.
