The ASAS-SN Catalog of Variable Stars I: The Serendipitous Survey

Distribution of ASAS-SN variable stars on sky.

Light curves of sample eclipsing binaries from ASAS-SN.

Michał Pawlak helped create the first catalog of variable stars from ASAS-SN. Full version of the paper led by Tharindu Jayasinghe is available as arXiv:1803.01001. More variable stars are coming soon!

We are interested in connecting theory, observations, and data modelling of time-domain phenomena in astronomy. This includes transients such as core-collapse supernovae and stellar mergers, persistent variable sources such as eclipsing binaries and pulsating stars, and stellar dynamics. We do (radiation)(magneto)hydrodynamics on supercomputers, semi-analytic models, and machine learning of astronomical data. Come meet us at Science coffee every Tuesday and Thursday at 2.30pm in KVAS room at ITP.

We are supported by the ERC Starting grant Cat-In-hAT to develop new computational methods to study binary star mergers, common envelope, and the associated transients. We are also support by Czech Science Foundation to study mass transfer in binaries. In the past, we received Czech-American collaboration grant from the Czech Ministry of Education, Youth, and Sports to participate in the ASAS-SN survey and the Primus award PRIMUS/SCI/17 from the Charles University.
