TL;DR
This paper presents a comprehensive analysis of epsilon Aurigae by compiling 110 years of radial velocity data and recent photometric observations to derive a new precise ephemeris and orbital solution.
Contribution
The study provides the first extensive 110-year radial velocity dataset combined with recent photometry to refine epsilon Aurigae's orbital parameters.
Findings
New precise ephemeris for epsilon Aurigae
Refined orbital solution based on 110 years of data
Improved understanding of eclipse timing and orbital dynamics
Abstract
We collected rich series of RV measurements covering last 110 years and photometric observations from the past 6 primary eclipses, complemented them by our new observations and derived a new precise ephemeris and an orbital solution of epsilon Aur.
