Abstract
Jan 04, 2021 6 Cassiopeiae is a hot white hypergiant star, around 25 times more massive than our Sun, and 200,000 times more luminous. It is an Alpha Cygni variable star, having an apparent magnitude of +5.43. 6 Cassiopeiae is situated at around 8,000 light-years away from us. Its average surface temperatures have been recorded at around 10,023 K. Gamma Cassiopeiae is known to have two faint optical companions, designated components B and C, respectively. “B” is located about 2 seconds of arc away, and has an apparent visual magnitude of 11, while “C” is located only about one second of arc away, and has an apparent visual magnitude of 13. Jan 04, 2021 6 Cassiopeiae. 6 Cassiopeiae is a hot white hypergiant star, around 25 times more massive than our Sun, and 200,000 times more luminous. It is an Alpha Cygni variable star, having an apparent magnitude of +5.43. 6 Cassiopeiae is situated at around 8,000 light-years away from us. Its average surface temperatures have been recorded at around.
Propagation of discrete absorption components along the broad wind profiles of H and Fe II has been observed for the first time for a white hypergiant (6 Cas A2.5 Ia-0). CCD-echelle spectrometers of 6-m and 1-m telescopes of SAO RAS were used. The motion of the discrete components was traced for a period of 200 days in the 50 to 180 km s−1 interval of expansion velocity. The observed phenomenon is similar to that described for P Cygni. Corraboration of pulsations of 6 Cas has been obtained.
