An Unusual Quadruple System ? Tauri

Original language description

A preliminary analysis of spectroscopic, photometric and interferometric observations of the triple subsystem of a hierarchical quadruple system ? Tau is presented. The triple system consists of a close eclipsing binary (P^{A} = 7fd146651), revolving around a common centre of gravity with a distant tertiary (P^{B} = 145.17&d). All three stars have comparable brightness. The eclipsing pair consists of two slowly-rotating A stars while the tertiary is a rapidly-rotating B star. The outer orbit is eccentric (e^{B} = 0.237 0.022). Available electronic radial velocities indicate an apsidal advance of the outer orbit with a period P_{APS}^{B} = 224 147 yr.
