안녕하십니까. 이번주 수요일(11월 30일) 오전 10:30에 아래와 같이 정규 콜로퀴움이 진행될 예정입니다. 많은 참여 부탁드립니다. 발표자 : 이영대 박사 (충남대학교) 호스트 : 박홍수 (광학천문본부) 장소 : 장영실홀 331-2 및 원격 연결 일시 : 11월 30일 (수) 오전 10:30 접속주소 : https://us02web.zoom.us/j/84597516884?pwd=OHVjOEQra1lSZ242K2tOZWY4T2Nzdz09 교육학점: 천문연 소속 현장참석자의 경우 필수 0.5 학점 부여 제목: Searching rare dwarf novae using KMTNet 초록: Dwarf
novae are a binary system with short orbital periods (a few minutes to hours).
Being one of the cataclysmic variable stars, dwarf novae show quasi-periodic
outbursts which are triggered in the accretion disk around the primary star via
accreting materials from the secondary star. During outbursts, they show
various peculiar shapes of the observed light curves. For the past ~70 years,
over five thousand dwarf novae have been observed and outburst mechanisms
became well known. Thermal-viscous instability makes accumulated mass in the
accretion disk dumped onto the primary star during the outburst and the
accretion disk become brightened. Despite the many previous studies, some parts
of the evolution of dwarf novae are still unknown since, especially, dwarf
novae with very short orbital periods of <60 minutes or low-metallicity
secondary stars are rarely observed. KMTNet has the ability to discover these
rare dwarf novae and in this talk, I will show the strength of the KMTNet in
finding these invaluable pieces to get better understanding of their evolution. 진행언어 : 한국어 슬라이드언어 : 영어 원격 접속 방법 : A. 웹 브라우저 : Chrome을 추천하며 아래 주소를 실행시 Zoom 구동을 위한 프로그램이 설치될 수 있음 2022년 하반기 KASI 콜로퀴움 일정 https://www.kasi.re.kr/kor/post/eng_colloquium (위 일정은 연사분의 상황에 따라서 변경될 수 있습니다.) 천문연 콜로퀴움 위원회 (홍성욱, 최지훈, 오희영) 드림 Dear all, KASI's regular colloquium is scheduled on this Wednesday,
