KIC 9028474: A Long-period Eclipsing Binary on a Highly Eccentric Orbit
The Astronomical Journal, 2023 We present a comprehensive analysis of a very long-period (124.93669 days) eclipsing binary KIC 9028474, which is composed of F9V+G1V components on a highly eccentric ( e = 0.82029) orbit.

New insight into the massive eccentric binary HD 165052: self-consistent orbital solution, apsidal motion, and fundamental parameters [PDF]
Monthly notices of the Royal Astronomical Society, 2023 HD 165052 is a short-period massive eccentric binary system that undergoes apsidal motion. As the rate of apsidal motion is directly related to the internal structure constants of the binary components, its study allows to get insight into the internal
