Beginning of ReadMe : J/other/PZ/30.4 BVRI photometry of nova V445 Pup (Goranskij+, 2010) ================================================================================ The progenitor and remnant of the helium nova V445 Puppis. Goranskij V.P., Shugarov S.Yu., Zharova A.V., Kroll P., Barsukova E.A. <Perem. Zvezdy, 30, 4 (2010)> =2010PZ.....30....4G ================================================================================ ADC_Keywords: Novae ; Photometry, UBVRI Abstract: V445 Pup was a peculiar nova having no hydrogen spectral lines in the outburst. The spectrum contained strong emission lines of carbon, oxygen, calcium, sodium and iron. We have performed digital processing of photographic images of the V445 Pup progenitor using astronomical plate archives. The brightness of the progenitor in the B band was 14.3mag. It was found to be a periodic variable star, its most probable period being 0d.650654+/-0.000011d. The light curve shape suggests that the progenitor was a common-envelope binary having a spot on the surface and variable surface brightness. The spectral energy distribution of the progenitor between 0.44 and 2.2um was similar to that of an A0V type star. Description: In the Moscow SAI plate collection, we found 51 plates with images of V445 Pup taken with the SAI Crimean Station 40-cm f/4 astrograph and dated between 15 November 1969 and 4 November 1989. We found 56 measurable images of V445 Pup on the plates of the Sonneberg Observatory collection dated between 19 March 1984 and 17 January 1991. Additionally, we measured all the Internet-accessible Digital Sky Survey images of V445 Pup in B,R, and I bands and used 2MASS JHK magnitudes to study the spectral energy distribution of the progenitor. We performed our observations of the V445 Pup remnant between 31 March 2003 and 20 October 2009. These observations were acquired in the Special Astrophysical Observatory (SAO), with the 1-m Zeiss reflector and CCD UBVRcIc photometer equipped with an EEV 42-40 CCD chip.
