Period of the Si-star in NGC 2169.

RENSON P.

Abstract (from CDS):

For the Si Ap-star known in NGC 2169 (Gr.9 in the cluster), a period between 0.60 and 0.62 d, most likely about 0.606 d, agrees with all known observations, and is much more probable than the perid 1.56 d proposed by Maitzen & Lebzelter (1993). The obtained period is among the shortest ones known for Ap stars.
