A massive pulsar irradiates a Solar-type star

Researchers from the UPC and the IAC discover one of the most massive neutron stars. Using a pioneering method, researchers from the Astronomy and Astrophysics Group of the Universitat Politècnica de Catalunya (UPC) and the Canary Islands Institute of Astrophysics (IAC) have found a neutron star of about 2.3 solar masses—one of the most massive…

A 2.3 Solar-mass neutron star in PSR J2215+5135

VIDEO: PSR J2215+5135 Orbital period: 4.14 hours Spin period: 2.61 milliseconds Distance from Earth: about 10.000 light-years The inner face of the companion star, strongly irradiated by the pulsar, is heated up to about 8100 degrees Kelvin. As a consequence, hydrogen absorption lines dominate the visible spectrum of the hot side of the star. The…
