Timing the X-ray pulsating companion of the hot-subdwarf HD 49798 with NICER
Michela Rigoselli, Davide De Grandis, Sandro Mereghetti +1
HD 49798 is a hot subdwarf of O spectral type in a 1.55 day orbit with the X-ray source RX J0648.0-4418, a compact object with spin period of 13.2 s. We use recent data from the NI…
Two decades of X-ray observations of the isolated neutron star RX J1856.5-3754: detection of thermal and non-thermal hard X-rays and refined spin-down measurement
Davide De Grandis, Michela Rigoselli, Sandro Mereghetti +6
The soft X-ray pulsar RX J1856.5-3754 is the brightest member of a small class of thermally-emitting, radio-silent, isolated neutron stars. Its X-ray spectrum is almost indistingui…
Three-Dimensional Magnetothermal Simulations of Magnetar Outbursts
Davide De Grandis, Roberto Turolla, Roberto Taverna +3
The defining trait of magnetars, the most strongly magnetized neutron stars (NSs), is their transient activity in the X/-bands. In particular, many of them undergo phases of enh…
