    Exploring more solutions for low-energy transfers to lunar distant retrograde orbits

    This study aims to explore more solutions for low-energy transfers to lunar distant retrograde orbits (DROs) from the vicinity of the Earth. Millions of transfer trajectories from a lunar free-return orbit (LF...

    Arbitrary /-state approximate solutions of the Hulthén potential through the exact quantization rule

    In this paper, using the Exact Quantization Rule, we present approximate analytical solutions of the radial Schrödinger equation with non-zero l values for the Hulthén potential in the frame of an approximation t...
