Relaxation of magnetically-confined mountains on accreting neutron stars through cross-field mass transport
Ryan Brunet, Andrew Melatos, Pedro Rossetto
Hydromagnetic instabilities modify the structure of a magnetically confined mountain on an accreting neutron star, once the accreted mass exceeds a critical value. Ideal magnetohyd…

Robust Wada Boundaries and Entropy Scaling in pp-Wave Spacetimes
Pedro Henrique Barboza Rossetto, Vanessa Carvalho de Andrade, Daniel Müller
We study the dynamics of the geodesics of pp-wave spacetimes with polynomial profiles, which are dynamically equivalent to the motion of a classical particle in a two-dimensional h…

Quadrupole Moment of a Magnetically Confined Mountain on an Accreting Neutron Star in General Relativity
Pedro Henrique Barboza Rossetto, Jörg Frauendiener, Andrew Melatos
General relativistic corrections are calculated for the quadrupole moment of a magnetically confined mountain on an accreting neutron star. The hydromagnetic structure of the mount…
