Three New Variable Stars Discovered in Cassiopeia during a Northern Sky Survey Session

摘要

This paper describes the discovery of three new variable stars in Cassiopeia—UCAC4 749-017875, UCAC4 749-017890, and UCAC4 749-018171. They are a pulsating star and two eclipsing binary systems, respectively, discovered in 2015 and included in the AAVSO Variable Star Index, but only now published due to lack of time. I encourage all observers to observe these stars further in order to better characterize them.
