V1135 Herculis: a double-lined eclipsing binary with an Anomalous Cepheid. (2013). Revista Mexicana De Astronomía Y Astrofísica, 49(2), 239-251. https://astronomia.unam.mx/journals/rmxaa/article/view/2013rmxaa..49..239s
Abstract
BVR light curves and radial velocities for the double-lined eclipsing binary V1135 Her were obtained. Our analyses of the multi-color light curves and radial velocities led to the determination of fundamental stellar properties of both components of the interesting system V1135 Her. The system consists of two evolved stars, G1+K3 between giants and supergiants, with masses of M_1=1.461±0.054 M_⊙ and M_2=0.504±0.040 M_⊙ and radii of R_1=27.1±0.4 R_⊙ and R_2=10.4±0.2 R_⊙. Most of the observed and calculated parameters of the V1135 Her and its location on the color-magnitude and period-luminosity diagrams lead to a classification of an Anomalous Cepheid.Similar Articles
