First Images of Cool Starspots on a Star Other than the Sun: Interferometric Imaging of Andromedae
J. R. Parks, R. J. White, F. Baron +14
Presented are the first interferometric images of cool starspots on the chromospherically active giant Andromedae. These images represent the first model-independent images of…
Ap stars with variable periods
Zdeněk Mikulášek, Jiří Krtička, Jan Janík +5
The majority of magnetic chemically peculiar (mCP) stars exhibit periodic light, magnetic, radio, and spectroscopic variations that can be adequately modelled as a rigidly-rotating…
HR 7355 - another rapidly braking He-strong CP star?
Z. Mikulasek, J. Krticka, G. W. Henry +3
Strong meridional mixing induced by rapid rotation is one reason why all hot main-sequence stars are not chemically peculiar. However, the finding that the He-strong CP star HR 735…
The nature of the light variability of the silicon star HR 7224
J. Krticka, Z. Mikulasek, G. W. Henry +4
Although photometric variations of chemically peculiar (CP) stars are frequently used to determine their rotational periods, the detailed mechanism of their light variability remai…
