Spectral variations in HD 190002: evidence of a companion. (1980). Revista Mexicana De Astronomía Y Astrofísica, 5(1), 285-288. https://astronomia.unam.mx/journals/rmxaa/article/view/1983rmxaa...5..285b

Abstract

Eight medium dispersion spectra of HD 190002 have been analyzed in the spectral range λλ4440-4800. The equivalent width and the profile of the C III λ4650-He II λ4686 blend shows periodic variability with a period of 8.16 days. The variation of the equivalent width of the line is interpreted as due to the periodic contribution to the continuum of the WC7 star by a secondary object.
