- Shell_star abstract "A shell star, also termed Gamma Cassiopeiae variable (GCAS), is a star having a spectrum that exhibits features indicating a circumstellar disc of gas surrounding the star at the equator. They exhibit irregular variations in their luminosity due to the outflow of matter. The shell stars are fast rotators, giving a partial explanation on the mechanism, but shell stars are still considered enigmatic. Shell stars belong to spectral types O7.5 to F5, but their spectra are characterized by enormously widened absorption lines due to fast rotation and the disc that contributes also to other spectral peculiarities. Rotation velocities are about 200–250 km/s, not far from the point when the rotational acceleration would disrupt the star. The spectra and general qualities of shell stars are hard to interpret, since normal spectral features are overlaid with variable emission, so luminosity class and exact spectral class might easily be misinterpreted.".
