Radio Colloquium

attachment This is a "weekly", very informal colloquium hosted by the radio division of KASI. Anyone can utilize this colloquium spot for a variety of purposes: e.g., to introduce interesting scientific/non-scientific results or news, to report about a meeting you recently attended, to practice your oral presentation for a coming meeting, and even to celebrate something. Depending on what to do, you can propose the meeting place as well: e.g., the seminar room (331-2) or the coffee/tea place of the Jangyoungsil hall. In the case of an oral presentation, ideally it is expected to be no longer than 30 min. Please contact me [ Dong-Kyu Jung, dkjung(at) ], if you have something to share.

매 주 금요일에 진행되는 전파 콜로퀴움은 전파천문본부에서 일어나는 다양한 연구와 소식 등을 편안한 분위기에서 공유하는 자리입니다. 예를 들면, 흥미로운 연구 결과, 유용한 생활 정보, 최근 참여한 미팅 소개, 다가오는 미팅 발표 연습, 축하연 등을 위한 시간으로 활용 가능합니다. 장소는 세미나룸, 휴게실 등 상황에 따라 제안하실 수 있으며, 발표 언어도 한국어, 영어 모두 대환영입니다. 발표는 가능한 30분을 초과하지 않도록 준비해 주시면 됩니다. 이 시간을 활용하시고자 하시면 언제든 연락주시기 바랍니다.

Title Chemical Diagnostics of a Massive Star-forming Region
Speaker Young Chol Minh (KVN group, KASI)
Abstract Massive stars are forming in the dense molecular cores deeply embedded in the GMCs. As specific chemical tracers, various molecular emissions from such as highly saturated species, sulfur-bearing species, deuterated species, and shock- or turbulent-tracing species provide unique information on the complicated early evolutionary phase of massive star formation. We introduce recent ALMA results of d ... more

Title KVN 박사후 연구원 Dr. Nobuyuki Sakai 소개 및 호주에서 한달살기 Welcoming new postdoc (N. Sakai) & Living in Sydney for a month
Speaker Taehyun Jung (KVN group, KASI)
Abstract NAOJ 미즈사와 VLBI 천문대에서 일하던 Nobuyuki Sakai 박사님이 KVN의 새로운 박사후연구원으로 3월 19일부터 근무를 시작하였습니다. Sakai 박사님에 대한 간략한 소개를 할 예정입니다. 많은 격려와 축하 부탁드립니다. 그리고 제가 지난 겨울에 호주에서 한 달 휴가를 보낸 경험을 잠깐 공유할까 합니다. 부담없이 많은 참석 부탁드립니다. ... more

Title Episodic Accretion in VeLLOs
Speaker Dr. Tien-Hao Hsieh (ASIAA)
Abstract We will present our recent studies about episodic accretion. Episodic accretion is proposed to solve the long-standing luminosity problem in star formation, but its detailed process is still poorly understood. We observed N2H+ and CO isotopologue using ALMA toward eight Very Low Luminosity Objects (VeLLOs). The spatial distributions of N2H+ and CO isotopologues show clear anti-correlation, highlig ... more

Title Constraining the infalling envelope of embedded protostars: BHR71 and its hot corinos
Speaker Mr. Yao-Lun Yang (UT-Austin)
Abstract Star formation processes such as infall, accretion, and outflows increase the complexity of molecules, allowing us to use those molecules to probe the physical environments where stars form. The most deeply embedded protostars present particularly rich spectra of molecules due to their dense envelope and active infall and outflows, making them best probed by molecular spectroscopy. Stars form via ... more

Title Water vapor toward high-mass star-forming regions and photodissociation regions (PDRs): the Herschel/HIFI view
Speaker Choi, Yunhee (Radio Science Group, KASI)
Abstract The purpose of this work is to study the physical and chemical evolution of high-mass star formation using H2O, which is a sensitive tracer of conditions in star-forming regions. Herschel/HIFI allows us to observe velocity-resolved multiple rotational transitions of H2O including the ground-state levels, and also its isotopologues. In addition, photodissociation regions (PDRs) are targeted to inve ... more
