Revised photometric properties for the multiperiodic variable HD 200925
1986
Publications of the Astronomical Society of the Pacific
Over 700 observations of HD 200925 in the uvby and ß systems have been secured and analyzed. Our data show that this variable is multiperiodic. A reddening value, E (b -y) = 0T029, has been derived from the observations. The reddening-corrected normals fory, (6-y), and c l yield a mean effective temperature, (T eff ) = 7020 K, a mean surface gravity, (log g) = 3.44, and a mean bolometric magnitude, (M h0] ) = 0 m 8. We determine a preliminary mean radius, (R) = 4.1 R ö . Our /77j data show that
