りゅう座BY型変光星
This is a BY Draconis variable, which means it undergoes changes in luminosity because regions of pronounced surface magnetic activity are moved into and out of the line of sight from the Earth as the star rotates (once every 11 days). It has a spectral class of K1 V, indicating that it is a K-type main sequence star. The star has 87% of the mass of the Sun and 82% of the Sun's radius. It is an estimated 3.76 billion years old. The star is radiating 48% of the Sun's luminosity from its photosphere at an effective temperature of 5,303 K.
