On the orbital period of the Intermediate Polar 1WGA J1958.2+3232.

ZHARIKOV S.V., TOVMASSIAN G.H. and ECHEVARRIA J.

Abstract (from CDS):

Recently, Norton et al. (2002A&A...384..195N) on the basis of multiwavelength photometry of 1WGA J1958.2+3232, argued that the -1 day alias of the strongest peak in the power spectrum is the true orbital period of the system, casting doubts on the period estimated by Zharikov et al. (2001A&A...366..834Z). We re-analyzed this system using our photometric and spectroscopic data along with the data kindly provided by Andy Norton and confirm our previous finding. After refining our analysis we find that the true orbital period of this binary system is 4.35h.
