Differential uvby Photometry of 13 Mon (A0 Ib)
Abstract
Differential uvby photometry of the A0 Ib supergiant 13 Mon obtained during three successive observing seasons shows that it is a low amplitude photometric variable, but no definite period is found. The variations in each filter are crudely in the phase. Further, the mean magnitude in each filter has slowly decreased in the course of the last three years.
