Super-slowly rotating Ap (ssrAp) stars: New spectroscopic observations
Gautier Mathys, Daniel L. Holdsworth, Marina Giarrusso +2
The rotation periods of Ap stars range over five to six orders of magnitude. The origin of their differentiation remains unknown. We carry out a systematic study of the longest per…

Super-slowly rotating Ap (ssrAp) stars: Spectroscopic study
G. Mathys, D. L. Holdsworth, M. Giarrusso +3
To gain better understanding of the Ap stars with the longest rotation periods, we obtained high resolution spectra of a sample of super-slowly rotating Ap (ssrAp) star candidates…
