Narrow Band Photometry of Rho Puppis

Abstract

Monochromatic flux values of the dwarf Cepheid Rho Puppis have been evaluated over the cycle from observations made in the 1967 season through four narrow band filters centred at 3858 A/sup0/ 4310 A/supo/, 4720 A/supo/ and 5975 A/supo/. The amplitudes at the above wavelengths are 0.17, 0.14, 0.12 and 0.09 magnitudes respectively. The effective temperatures variation over a cycle is 320/supo/K. Photoelectric light curves have also been obtained in Blue and Yellow colours and amplitude of light variations are 0/supm/.15 and 0/supm/.09 respectively. The period is further improved as 0.14088067 day.
