Distinct spectrum of Rho Persei

Mirfak, Algol and Gorgonea Tertia spectra through Paton Hawksley Star Analyzer grating filter 100 lines/mm

Rho Persei is a semiregular variable star of the μ Cephei type, whose apparent magnitude varies between 3.3 and 4.0 with periods of 50, 120 and 250 days. The star has reached the asymptotic giant branch of its evolution. It is near the tip of the red giant branch with a stellar classification of M4 II. The outer envelope has an effective temperature of 4,111 K, giving it the red-orange hue of an M-type star.
