Can solar sails be used to test fundamental physics?
چکیده انگلیسی

The relative importance of certain general relativistic effects is enhanced by solar radiation pressure (SRP). The observation and study of the trajectories of a solar sail could potentially provide tests of various effects of general relativity. In particular, we study Keplerian and non-Keplerian orbits near the sun as well as escape trajectories for a solar sail, for which general relativistic effects and the solar radiation pressure are considered simultaneously. In contrast with the conventional solar mission, a solar sail allows for non-Keplerian orbits, for which the orbital plane lies above the sun. It is predicted that there is an analog of the Lense–Thirring effect for non-Keplerian orbits. Also the SRP increases the amount of precession per orbit due to the Lense–Thirring effect for polar heliocentric orbits. A solar sail would also enhance the relative importance of effects associated with a possible net charge on the sun and during many rotations this effect may be measurable.


► Trajectories of solar sails give test of various effects of general relativity (GR).
► GR effects and the solar radiation pressure are considered simultaneously.
► Solar radiation pressure enhances GR effects on trajectories of a solar sail.
► There is an analog of the Lense–Thirring effect for non-Keplerian orbits.
► A solar sail would possible enhance effects associated with net charge on the sun.
