안녕하십니까.

이번주 수요일(12월 14일) 오전 10:30에 아래와 같이 정규 콜로퀴움이 진행될 예정입니다. 많은 참여 부탁드립니다. 이번주의 경우 온라인 세미나만 진행됩니다.

발표자 : Dr. Ross A. Burns (NAOJ)

호스트 : Kee-Tae Kim (전파천문본부)

장소 : 원격 연결

일시 : 12월 14일 (수) 오전 10:30

제목: Spiral structure in a high-mass protostellar disk observed with maser VLBI

초록: 

The high-mass protostar G358-MM1 underwent an accretion burst in 2019. Such events are rare, and essential to observe in order to test and refine theories of high-mass star formation. During the accretion burst six VLBI observations were made of the 6.7 GHz methanol maser in G358-MM1. The observations traced a 'heat-wave' of accretion energy as it moved through the disk. In this talk I will report the results of the VLBI monitoring campaign and introduce a new, and accidentally discovered, technique called 'heat-wave mapping' which used the accretion burst and multi-epoch VLBI observations to map the spatio-kinematics of the accretion disk at milliarcsecond resolution.

Title: Spiral structure in a high-mass protostellar disk observed with maser VLBI

Abstract: 

The high-mass protostar G358-MM1 underwent an accretion burst in 2019. Such events are rare, and essential to observe in order to test and refine theories of high-mass star formation. During the accretion burst six VLBI observations were made of the 6.7 GHz methanol maser in G358-MM1. The observations traced a 'heat-wave' of accretion energy as it moved through the disk. In this talk I will report the results of the VLBI monitoring campaign and introduce a new, and accidentally discovered, technique called 'heat-wave mapping' which used the accretion burst and multi-epoch VLBI observations to map the spatio-kinematics of the accretion disk at milliarcsecond resolution.
