Photoelectric measures of hydrogen lines in helium-weak stars. (1976). Revista Mexicana De Astronomía Y Astrofísica, 2(1), 331-337. https://astronomia.unam.mx/journals/rmxaa/article/view/1978rmxaa...2..331f
Abstract
Photoelectric measures of the Balmer lines Ha, H and Hy in helium-weak stars and also in some stars employed as standards are presented. From 12 helium-weak stars which were measured, 9 are located in the (a, p) array indicating earlier spectral type than their NIK classification. The other 3 stars suggest no difference with their classified MK spectral type. Similar results are derived from their UBVRI photometry.Similar Articles
