We present an updated spectroscopic orbit and a new visual orbit for the double-lined spectroscopic binary σ2 Coronae Borealis (CrB) based on radial velocity measurements at the Oak Ridge Observatory in Harvard, MA and interferometric visibility measurements at the Center for High Angular Resolution Astronomy (CHARA) Array on Mount Wilson in California. σ2 CrB is composed of two Sun-like stars of roughly equal mass in a circularized orbit with a period of 1.14 days. The long baselines of the…

Magnetic field topology of the cool, active, short-period binary system σ2 Coronae Borealis
Aims. The goal of this work is to study the cool, active binary star σ 2 CrB, focussing on its magnetic field. The two F9–G0 components of this system are tidally locked and in a close orbit,
