Mathematics for Input Space Probes in the Atmosphere of Gliese 581d.

Authors: R. Gobato, A. Gobato, D. F. G. Fedrigo

The work is a mathematical approach to the entry of an aerospace vehicle, as a probe or capsule in the atmosphere of the planet Gliese 581d, using data collected from the results of atmospheric models of the planet. GJ581d was the first planet candidate of a few Earth masses reported in the circum-stellar habitable zone of another star. It is located in the Gliese 581 star system, is a star red dwarf about 20 light years away from Earth in the constellation Libra. Its estimated mass is about a third of that of the Sun. It has been suggested that the recently discovered exoplanet GJ581d might be able to support liquid water due to its relatively low mass and orbital distance. However, GJ581d receives 35% less stellar energy than the planet Mars and is probably locked in tidal resonance, with extremely low insolation at the poles and possibly a permanent night side. The climate that demonstrate GJ581d will have a stable atmosphere and surface liquid water for a wide range of plausible cases, making it the first confirmed super-Earth (2-10 Earth masses) in the habitable zone. According to the general principle of relativity, “All systems of reference are equivalent with respect to the formulation of the fundamental laws of physics.” In this case all the equations studied apply to the exoplanet Gliese 581d. If humanity is able to send a probe to Gliese 581d, this has all the mathematical conditions set it down successfully on its surface.
