In the elliptic restricted three-body problem framework, periodic orbits are multi-revolution (MR) orbits. In the conventional approach to design an MR orbit, the circular halo orbit initial conditions are used with continuation on eccentricity and by dividing the whole orbit into multiple segments. An alternativescheme based on differential evolution is developed which avoids the continuation on eccentricity and treats the whole trajectory (MR orbit) as a single segment. The design and analysis of different MR orbits in the Sun–Earth system are presented. Unlike in the differential correction based method, the proposed methodology could produce both Lyapunov and halo orbit MR solutions for the same period. Further, it could capture multiple solutions for each of the halo or Lyapunov MR orbits. Multithreading technique has been employed to reduce the computational time.

Continuous Article Publishing mode
Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
