Peering into the Dark Side: Magnesium Lines Establish a Massive Neutron Star in PSR J2215+5135
Abstract New millisecond pulsars (MSPs) in compact binaries provide a good opportunity to search for the most massive neutron stars. Their main-sequence companion stars are often strongly irradiated by the pulsar, displacing the effective center of light from their barycenter and making mass measurements uncertain. We present a series of …
