Fast spectroscopic variability in AP stars. I. HD 11503. (1991). Revista Mexicana De Astronomía Y Astrofísica, 22(1), 249. https://astronomia.unam.mx/journals/rmxaa/article/view/1991rmxaa..22..249l
Abstract
Recent spectroscopic observations obtained consecutively in a time greater than the proposed photometric short period of the Ap star HD 11503 indicate that the intensities of some lines vary in the same time span as the photometric period. In a similar study, it is found that HD 11502, which, along with HD 11503, constitutes the binary system ADS 1507 (Gamma Ari), does not belong to the Ap class as was previously suggested.Similar Articles
