Photometric variability of the binary HD 1826. (1987). Revista Mexicana De Astronomía Y Astrofísica, 14(1), 410-413. https://astronomia.unam.mx/journals/rmxaa/article/view/1987rmxaa..14..410g
Abstract
Photoelectric two-color measurements of the single-lined spectroscopic binary HD 1826 are presented showing its photometric variability. The period of the light variations has been found to be in excellent agreement with the orbital period derived from the radial velocity measurements. An estimation of the amplitude of the variations of 0.03 mag has been obtained roughly independent of color. The system appears to be an ellipsoidal variable and the available preliminary results are discussed in light of the most probable binary model.Similar Articles
