The symbiotic star near the globular cluster NGC 6401. (1980). Revista Mexicana De Astronomía Y Astrofísica, 5(1), 51-58. https://astronomia.unam.mx/journals/rmxaa/article/view/1980rmxaa...5...51t
Abstract
Spectrophotometric observations of the emission line object near the globular cluster NGC 6401 discovered by Peterson (1977), Pt-1, are presented. It is found that Pt-1 is a symbiotic star and not a planetary nebula; its spectra show TiO bands in absorption and very strong H and He lines in emission, and there are no forbidden lines present. The observed He lines are about one order of magnitude stronger than predicted; it is suggested that this is partly due to collisional redistribution of the angular momentum for levels with n greater than 2.Similar Articles
