THE FK COMAE-TYPE CANDIDATE 1E 1751+7046 - UBVRI PHOTOMETRY

New UBVRI photometry of the FK Comae-type candidate 1E 1751 + 7046 is presented and the photometric rotation period P(phot) = 13.d9820 +/- 0.d0078 is derived. The peak to peak amplitude of the rotational modulation of brightness (nearly O.m3 in V) is extremely high. The previously observed, apparent...

Description
Summary:New UBVRI photometry of the FK Comae-type candidate 1E 1751 + 7046 is presented and the photometric rotation period P(phot) = 13.d9820 +/- 0.d0078 is derived. The peak to peak amplitude of the rotational modulation of brightness (nearly O.m3 in V) is extremely high. The previously observed, apparently constant, radial velocity may vary with a period P(rad) = 13.d912 +/- 0.d025.
