Nonlinear electrodynamics in magnetars: systematic effects on radius constraints and timing analysis
Gabriel A. Porto, Jonas P. Pereira, Eduardo Bittencourt +1
Magnetars are among the most extreme laboratories in the universe, harboring surface magnetic fields reaching ~G. At these supercritical scales, Maxwell's linear electrody…

Dynamical tides in neutron stars with first-order phase transitions: the role of the discontinuity mode
Jonas P. Pereira, Lucas Tonetto, MichaÅ Bejger +2
During the late stages of a binary neutron star inspiral, dynamical tides induced in each star by its companion become significant and should be included in complete gravitational-…

Evidence for 3XMM J185246.6+003317 as a massive magnetar with a low magnetic field
Rafael C. R. de Lima, Jonas P. Pereira, Jaziel G. Coelho +10
3XMM J185246.6+003317 is a transient magnetar located in the vicinity of the supernova remnant Kes\,79. So far, observations have only set upper limits to its surface magnetic fiel…
