The Long-Term Future of Space Travel
Jeremy S. Heyl
The fact that we apparently live in an accelerating universe places limitations on where humans might visit. If the current energy density of the universe is dominated by a cosmolo…
Magnetars
Jeremy S. Heyl
Ultramagnetized neutron stars or magnetars are magnetically powered neutron stars. Their strong magnetic fields dominate the physical processes in their crusts and their surroundin…
R-Modes on Rapidly Rotating, Relativistic Stars : II. Blackbody Emission
Jeremy S. Heyl
Rossby waves (or r-modes) on the surface of a neutron star have become a leading model for the oscillations observed during the tail of Type-I X-ray bursts. Their frequency evoluti…
The High-Energy Polarization-Limiting Radius of Neutron Star Magnetospheres II -- Magnetized Hydrogen Atmospheres
Jeremy S. Heyl, Don Lloyd, Nir J. Shaviv
In the presence of strong magnetic fields, the vacuum becomes a birefringent medium. We show that this QED effect couples the direction of the polarization of photons leaving the N…
A QED Model for Non-thermal Emission from SGRs and AXPs
Jeremy S. Heyl, Lars Hernquist
Previously, we showed that, owing to effects arising from quantum electrodynamics (QED), magnetohydrodynamic fast modes of sufficient strength will break down to form electron-posi…
