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.

Title: Searching rare dwarf novae using KMTNet

Abstract: 

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.
