Detection of the 3-rd and 4-th companions in the hierarchical quadruple system RV CVn — E8 Intelligence Research
Year: 2026
Type: preprint
Abstract: RV CVn is a known double-lined W UMa-type eclipsing binary with well-determined masses of both components. In this study, the orbital period variation and multiplicity of the RV CVn system are investigated, combining eclipse timing analysis, direct imaging, and Gaia astrometry. It is found that the updated O-C variation is caused by a tertiary companion with an orbital period of P3=105.8±7.5 yr, high eccentricity of e3=0.84± Author: Andrew Stewart Caldin, Independent Researcher, UK.
