UBVRI photometry of CP Puppis - A magnetic nova?

M. P. Diaz, J. E. Steiner

Abstract

Results of about 16 hours of UBVRI photometry of Nova Pupis 1942 are presented. A modulation of the (B-V) color index with the 88-minute orbital period is found. This modulation is interpreted as a possible evidence for a strongly magnetized white dwarf in the system, and a comparison with other novae that are polars or intermediate polars is made.
