New data on a-type disk stars.


Abstract (from CDS):

After a review of what has been learned to date about the Ti II disk lines at λλ3759 and 3761 in the spectra of rapidly rotating A dwarfs, new measures obtained during the past 10 yr are given. They show stars with quasi-periodic variations of 15-30 yr (as in Be stars) and probably longer. The star HR 10 has double disk lines that change relative strengths during 9 yr, consistent with the behavior found by others. They support the model by others of erratic longward components representing material falling onto the star.
