Abstract
FUZZINESS OF SOME VARIABLE STARS.—Mr. Cuthbert G. Peek has, during the last six years, used his 6¼-imch achromatic for the investigation of the light-curves of variable stars. In this month's Knowledge he describes some observations of changes in appearance of a few variable stars at different epochs. Three variables—T Cassiopeia, R Cassiopeiæ, and S Herculis—have been frequently observed as (a) remarkably well defined, almost planetary, disks; (b) well-defined stars, surrounded by a more or less dense, ruddy atmosphere; (c) large, woolly, ill-defined images, resembling a small but bright planetary nebula; (d) at minimum, in place of the variable, a slight bluish nebulosity. The changes appear to be real, for stars near the places of the variables have been seen clear and sharp when the haziness of the variables was unmistakable. Other stars with regard to which Mr. Peek has made similar observations are S Cassiopeiæ, R Tauri, R Aurigæ, V Cancri, R Ursæ Majoris, S Ursæ Majoris, R Camelopardi, R Boötis, S Coronæ, R Aquilæ, and S Cephei.
