RR Lyrae stars in the outer region of the globular cluster M3: A shortage of long periods at r ∼ 3.5 to 6 arcmin?

BUTLER D.J.

Abstract (from CDS):

An analysis of the radial distribution of ab-type RR Lyrae star periods in the outer region of the globular cluster M3 at r≥0.83' has been performed. That analysis points towards a real shortage of stars with long periods in the radial distance range 3.5' to 6' (or about 7 to 12 core radii). A brief discussion is presented. The origin of the phenomenon remains an open question.
