Abstract
LIGHT-VARIATIONS OF Y CYGNI.—The British Astronomical Journal, No. 266, contains two contributions from Mr. S. Yendell and Prof. Dunér, the former “On some observed minima of Y Cygni,” and the latter “On the chief cause of the anomalies in the light-variations of Y Cygni.” Mr. Yendell in his paper thoroughly agrees with the explanation put forward by Prof. Dunér to account for the anomalies in the light-variations, and says that, when the two series of observations are taken simultaneously, “the substantial correctness of his (Dunér's) fundamental assumption appears to me to be proved beyond the possibility of a cavil.” It may be remembered that, in Prof. Dunér's former paper on this subject, he was struck with the discordance of some of Mr. Yendell's observations, which did not seem to harmonize with his own suggested explanation. These observations are now published in detail in this paper, and will be read with interest by those who are following up this curious variable.
