Ab initio simulations of neutron stars' oblique electrospheres with realistic neutron star parameters
Fabrice Mottez
Electrospheres are environments with the same origin as pulsars; a highly magnetized rotating neutron star. In pulsars, a cascade of electron-positron pair creation enriches the pl…
Periodic activity from fast radio burst FRB180916 explained in the frameof the orbiting asteroid model
Guillaume Voisin, Fabrice Mottez, Philippe Zarka
Observation of fast radio bursts (FRBs) are rising very quickly with the advent of specialised instruments and surveys, and it has recently been shown that some of them repeat quas…
General solution for the vacuum electromagnetic field in the surroundings of a rotating star
S. Bonazzola, F. Mottez, J. Heyvaerts
Aims. Many recent observations of pulsars and magnetars can be interpreted in terms of neutron stars (NS) with multipole electromagnetic fields. As a first approximation, we invest…
Repeating fast radio bursts caused by small bodies orbiting a pulsar or a magnetar
Fabrice Mottez, Philippe Zarka, Guillaume Voisin
Asteroids orbiting into the highly magnetized and highly relativistic wind of a pulsar offer a favourable configuration for repeating fast radio bursts (FRB). The body in direct co…
The Giant Radio Array for Neutrino Detection (GRAND): Science and Design
GRAND Collaboration, Jaime Alvarez-Muniz, Rafael Alves Batista +48
The Giant Radio Array for Neutrino Detection (GRAND) is a planned large-scale observatory of ultra-high-energy (UHE) cosmic particles, with energies exceeding 10^8 GeV. Its goal is…
Electron-positron pair production by gamma rays in an anisotropic flux of soft photons, and application to pulsar polar caps
Guillaume Voisin, Fabrice Mottez, Silvano Bonazzola
Electron-positron pair production by collision of photons is investigated in view of application to pulsar physics. We compute the absorption rate of individual gamma-ray photons b…
Quantum theory of curvature and synchro-curvature radiation in a strong and curved magnetic field, and applications to neutron star magnetospheres
Guillaume Voisin, Silvano Bonazzola, Fabrice Mottez
In a previous paper, we derived the quantum states of a Dirac particle in a circular, intense magnetic field in the limit of low momentum perpendicular to the field with the purpos…
Dirac states of an electron in a circular intense magnetic field
Guillaume Voisin, Silvano Bonazzola, Fabrice Mottez
Neutron-star magnetospheres are structured by very intense magnetic fields extending from 100 to 10 5 km traveled by very energetic electrons and positrons with Lorentz factors up…
Do asteroids evaporate near pulsars? Induction heating by pulsar waves revisited
Kumiko Kotera, Fabrice Mottez, Guillaume Voisin +1
We investigate the evaporation of close-by pulsar companions, such as planets, asteroids, and white dwarfs, by induction heating. Assuming that the outflow energy is dominated by a…
