Radial-velocity curves of both components were obtained. (2) The light variations arise from superposition of variations on at least three time scales: phase-locked orbital brightness and colour changes with two minima; sinusoidal variation with a 322.24^d^ period and low-amplitude rapid changes with a possible period of 1.6738^d^. (3) A tentative solution of the B and V light curves which assumes the semi-detached configuration and presence of a disk around the primary, combined with the orbital solution, leads to preliminary basic physical elements of the system which are consistent with the radiative properties of the binary components.1997A&A...324..965Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/324/965CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/328/551 : Spectroscopic data of 4 Herculis.
