We perform force-free simulations for a neutron star orbiting a black hole, aiming at clarifying
the main magnetosphere properties of such binaries toward their innermost stable circular …

We conduct force-free simulations of a single neutron star undergoing orbital motion in flat
spacetime, mimicking the trajectory of the star about the center of mass on a compact binary …

ABSTRACTJP Several important properties of rotation-powered millisecond pulsars (MSPs),
such as their mass-radius ratio, equation of state and magnetic field topology, can be …

Because mergers of black hole–neutron star (BH–NS) binaries are widely argued to
produce both gravitational and electromagnetic waves, these binaries are among the most …

In this chapter, we give an overview of our current understanding of the physics of accreting
massive black hole binaries (MBHBs), with a special focus on the latest developments in …

Astrophysical jets are plasma flows, which are observed to substantially maintain their
transverse size while travelling distances orders-of-magnitude larger. They are found in …

Astrophysical jets are collimated plasma outflows observed in diverse astrophysical settings
covering seven decades of spatial scale and twenty decades of power, which, nevertheless …

The accretion disks around black holes consist of infalling matter boosted almost to the
speed of light making collisions with opposite counterpart. This is the rough picture occurring …

We study sky maps and light curves of gamma-ray emission from neutron stars in compact
binaries, and in isolation. We briefly review some gamma-ray emission models, and …

In the current multi-messenger era of astronomy, the low-inertia limit of magneto-
hydrodynamics, or “force-free” electrodynamics, has regained attention as a first …
