spectrum variable | star | Main-sequence Am or Ap stars whose spectra show anomalously strong lines of metals and rare earths which vary in intensity by about 0.1 mag over periods of about 1-25 days. They are characterized by large magnetic fields (103-104 gauss) at the surface, small variations in light and color, and small projected rotational velocities. These peculiarities are sometimes interpreted in terms of an oblique rotator. | |||
alpha2 CVn | Canes Venatici | spectrum variable | A spectrum variable with spectrum showing strong, profuse lines of rare earths, iron-peak elements, and Si. | 5.469 days |
