Abstract:Pulsating ultra-luminous X-ray sources (PULXs) are characterised by an extremely large luminosity (> 10 40 erg s −1 ). While there is a general consensus that they host an accreting, magnetized neutron star (NS), the problem of how to produce luminosities > 100 times the Eddington limit, 𝐿 𝐸 , of a solar mass object is still debated. A promising explanation relies on the reduction of the opacities in the presence of a strong magnetic field, which allows for the local flux to be much larger than the Eddington… Show more
