1965 light curves of BV Dra and BW Dra

Autor: Douglas S. Hall, Robert H. Hardie

Publikováno v: Journal of Astrophysics and Astronomy. 11:265-270

Differential B-band photometry of BV Dra and BW Dra, obtained in 1965, is presented. Times of primary and secondary minima are derived and combined with published times for a period study. Period variations are found in both binaries and magnetic cyc

UBV photometry of the Ap variable UZ Psc = HD 10783

Autor: Douglas S. Hall, Edwin J. Reichmann, Robert H. Hardie, Edward W. Burke

Publikováno v: Journal of Astrophysics and Astronomy. 11:277-280

The photometric variability of the Ap star HD 10783 = UZ Psc is discussed. New UBV photometry, obtained between late 1965 and early 1969, is presented and it is combined with existing published photometry to derive an improved ephemeris for times of
