Vermutlich handelt es sich um ein enges Doppelsternsystem, bestehend aus einem Riesenstern und einem Neutronenstern. Best Solar 2018. The X-ray radiation emanating from the star is about 10 times stronger than the radiation detected from other Be or B stars. Since there were no signs of a companion in the spectrum of Gamma Cassiopeiae, the system was adopted as a single-lined spectroscopic binary, that is to say, a system where the spectrum of only one component is seen and the presence of a companion is inferred from spectral lines periodically shifting towards the blue, then towards red and then towards blue again, indicating that the components are moving toward us and away from us, i.e. Cassiopeia also contains two well-known supernova remnants: Tycho’s Star (3C 10), the remnant of a Type Ia supernova (SN 1572) observed in November 1572, and Cassiopeia A, the brightest extrasolar radio source in the sky. Measurements of the star’s radial velocities led to the discovery that Gamma Cassiopeiae was a spectroscopic binary system. Emission and reflection nebulas located in Cassiopeia. These stars exhibit irregular brightness variations over periods of decades. This is the gamma-Cassiopeia Nebula. IC59 & IC63: The Gamma Cassiopeiae Nebulae Gamma Cassiopeiae, the middle star of the famous W-shaped constellation, is a hot giant with a surface temperature of 25,000°C (compared to 5,500°C for our Sun) and a mass fifteen times our Sun's.

This asterism is formed by five bright stars; Epsilon, Ruchbah (Delta), Gamma, Schedar (Alpha Cassiopeiae) and Caph (Beta Cassiopeiae). It is the central star of Cassiopeia’s W pattern. The variations in brightness are caused by shell episodes, where shell features appear in the star’s spectrum, significantly increasing or decreasing brightness. Its poles are closer to the centre of mass and therefore hotter and more luminous than the equatorial region. IC 59 lies a bit farther from the star and shows less hydrogen-alpha emission and more reflected blue light.
