TL;DR
This study utilized robotic telescopes to monitor a two-square-degree sky area, analyzing thousands of star images over six months to identify new exoplanet candidates through transit detection.
Contribution
First large-scale exoplanet survey using robotic telescopes at SAO RAS, discovering five new exoplanet candidates and providing detailed light curves for binary stars.
Findings
Discovered five new exoplanet candidates.
Analyzed 25,000 images over six months.
Provided light curves for dozens of binary stars.
Abstract
We used the 0.5-m robotic telescopes located at the Special Astrophysical Observatory of the Russian Academy of Sciences for monitoring two square degrees of the sky with the aim of detecting new exoplanets. A dimming of the visible brightness is expected due to the exoplanets transiting their host stars. We analyzed about 25000 raw images of stars taken in the period between August 2020 and January 2021 and plotted the light curves for about 30000 stars on a half-year timescale. Five newly discovered exoplanet candidates are being investigated to determine their transit event parameters. We also present the light curves for dozens of binary stars.
