Abstract
THE VARIABLE-STAR ALGOL.—Considering the long period during which this star has been under observation, and the many investigations which have been made with the view to reduce its fluctuations of light within some law, much interest attaches to a remark by Prof. Winnecke that the times of minima of Algol in the last year have fallen about one hour earlier than those assigned in the ephemerides of variables published by the Astronomische Gesellschaft. Dr. Julius Schmidt, director of the Observatory at Athens, to whom we owe the greater number of recent observations on this star, has not yet made known his results for 1878, but we have his determinations of the times of minima in 1875–76–77. For comparison with them we may take the last formula given by Prof. Schönfeld in his second catalogue of the variable stars, which appeared in 1875, viz., for Paris mean time:—
