How to measure one of the periods of this multiple star system with an eShel spectrograph?
By carrying out a measurement campaign over 12 nights from December 2016 to January 2017, I was able to calculate the main period of this star and to demonstrate the presence of a shorter period within the main period.
All process made with ISIS software and Mathlab.
