Methanol masers in the disk and outflow of IRAS13481-6124
Abstract
IRAS13481-6124 is a massive young stellar object (MYSO) with clear evidence for disk accretion and outflow activity. Our recent ATCA observations (C2345) not only led to the detection of the thermal dust emission from the disk but also revealed the presence of Class I methanol masers and SiO emission. This opens up the possibility to study the shocked gas of the most powerful MYSO outflow in great detail. Consequently, the current application aims at high-resolution mapping of the Class I 44 GHz masers as well as the SiO (1-0) line. Furthermore, sensitive 6.7 GHz measurements shall be attempted to search for Class II masers. The latter may be used to characterize the dense warm gas close to the central source. Simultaneously, we will reach an unprecedented sensitivity to the radio continuum which renders the detection of the ionized wind possible.
