안녕하십니까.

이번주 수요일(11월 2일) 오전 10:30에 아래와 같이 정규 콜로퀴움이 진행될 예정입니다. 많은 참여 부탁드립니다. 이번주의 경우 온라인 세미나만 진행됩니다.

발표자 : Dr. Do Thi Hoai (Vietnam National Space Center)

호스트 : Nguyen Thi Phuong (전파천문본부)

장소 : 원격 연결 (해외 거주 연사로 온라인 진행)

일시 : 11월 2일 (수) 오전 10:30

제목: Circumstellar envelopes of Oxygen-rich AGB stars

초록: 

Spherical symmetry breaking in the transition from Red Giant to Planetary Nebula, and the mechanism that governs it, have been a topic of intense interest for decades. Recent observations with high sensitivity and angular resolution have shown that spherical symmetry breaking was already present, in many cases, in the early AGB phase. At large distances from the star the circumstellar envelopes of AGB stars have been shown very complex with many fragments in the form of bipolar outflows, blobs, arcs and spirals. At smaller distance, the nascent winds share some features which need to pay attention including the presence of line broadening in the inner layer, the strong absorption of SiO emission over and beyond the stellar disc and the rotation within 30 au or so from the star. In this presentation, I will review the properties of their circumstellar envelopes (CSE) and their nascent winds with the aim of revealing significant similarities or differences in the hope of improving our understanding of the mechanisms at stake.

Title: Circumstellar envelopes of Oxygen-rich AGB stars

Abstract: 

Spherical symmetry breaking in the transition from Red Giant to Planetary Nebula, and the mechanism that governs it, have been a topic of intense interest for decades. Recent observations with high sensitivity and angular resolution have shown that spherical symmetry breaking was already present, in many cases, in the early AGB phase. At large distances from the star the circumstellar envelopes of AGB stars have been shown very complex with many fragments in the form of bipolar outflows, blobs, arcs and spirals. At smaller distance, the nascent winds share some features which need to pay attention including the presence of line broadening in the inner layer, the strong absorption of SiO emission over and beyond the stellar disc and the rotation within 30 au or so from the star. In this presentation, I will review the properties of their circumstellar envelopes (CSE) and their nascent winds with the aim of revealing significant similarities or differences in the hope of improving our understanding of the mechanisms at stake.
