Abstract

An assessment concerning neutron stars and space propulsion implications

Author(s): P.A.Murad

There are many uncertainties concerning stellar evolution of neutron stars. Neutron stars might possess multipolar architecture in lieu of a single dipole claimed by the conventional wisdom. The multipole issue cannot be resolved using a single observer reference point such as the Earth, but would require an additional non-terrestrial observer location with a significant offset. Without observing multiple beacons, we could not verify or deny the existence of multiple poles from observing the sweeping lighthouse effect from Earth. Moreover, a neutron starÂÂ’s magnetic field may be created by differences between the neutron core and a gas surface layer of protons and electrons. These differences between the layers constitute charges and moving currents that result in a magnetic field supported by a fast moving rotating core. If electrons in Cooper pairs exist in a neutron star, then the amount of magnetism may increase by a similar order via superconductivity. By symmetry, proton pairs should also exist to produce similar charge redistribution. Observing the different layers where an electron gas probably evaporates, rotating a proton gas over a neutron core can develop a strong magnet. These issues warrant further discussions as well as a proposal that provides implications for developing a space propulsion scheme.
