Description:
Several mostly unrelated periods or time scales characterize the
variability of HR 2501. This star is a new lambda Eri star with a
period of 0.79187d. This star also exhibits a mid- to long-term
variability of characteristic time ∼500d, most probably a consequence
of the recurrent outbursts of matter from the rapidly rotating Be star
towards its disk.
