Description
M82 X-2, an ultraluminous X-ray source in M82, was recently shown to harbor an accreting neutron star. Its luminosity being ~100 times the Eddington limit for a neutron star, it poses some problems to the existing theoretical framework about accretion onto neutron stars.
I will talk about the proprieties and behavior of this source, how it was unveiled as a neutron star, the possible theoretical interpretations and some preliminary results coming from new observations of the M82 field.
