Spectral variations of HD 192163. (1980). Revista Mexicana De Astronomía Y Astrofísica, 5(1), 45-49. https://astronomia.unam.mx/journals/rmxaa/article/view/1980rmxaa...5...45k
Abstract
Medium dispersion (0.7 A per channel) spectra of HD 192163 in the 4470-4800 A region are examined for profile and radial velocity variations. The star is variable in both senses. The mean velocity of the system is found to be approximately -100 km/sec. The profile variations are similar, but not so strong as those in HD 50896 which is known to be a binary. This analysis supports the idea that HD 192163 may be a binary system. The presence of a collapsed companion is suggested.Similar Articles
