Blazhko RR Lyr Variable Lightcurve Animation

This animation illustrates how the shape of an RR Lyr variable's lightcurve changes over the course of one Blazhko cycle. It is based on MACHO Project data reported in:

" The Blazhko Effect in RR Lyrae stars: Strong observational support
for the oblique pulsator model in three stars " by The MACHO Collaboration: C. Alcock, D.R. Alves, A. Becker, D.P. Bennett, K.H. Cook, K.C. Freeman, K. Griest, D.W. Kurtz, M.J. Lehner, S.L. Marshall, D. Minniti, B.A. Peterson, M.R. Pratt, P.J. Quinn, A.W. Rodgers, W. Sutherland, A. Tomaney, T. Vandehei and D.L. Welch.
