Notes
Zeta Persei (ζ Per, ζ Persei). This is a lower luminosity supergiant star with a stellar classification of B1 Ib.[3] This is an enormous star, with an estimated 26–27[8] times the Sun's radius and 13–16 times the Sun's mass.[7] It has about 47,000 times the luminosity of the Sun and it is radiating this energy at an effective temperature of 20,800 K,[7] giving it the blue-white hue of a B-type star.[14] The spectrum displays anomalously high levels of carbon.[15] Zeta Persei has a strong stellar wind that is expelling 0.23×10−6 times the mass of the Sun per year, or the equivalent of the Sun's mass every 4.3 million years.[16]
