Neutron Starquakes Could Shake Up Nuclear Physics

Terzan 5, located in the constellation Sagittarius, is a crowded globular cluster home to hundreds of thousands of stars.Ten unusual and exotic pulsars were recently discovered by an international team of astronomers from the U.S. National Science Foundation National Radio Astronomy Observatory, the Max Planck Institute for Gravitational Physics (Albert Einstein Institute) (AEI), and the Max Planck Institute for Radio Astronomy

Telescope Tag-Team Discovers Galactic Cluster’s Bizarre Secrets

This illustration depicts a binary star system consisting of a dense neutron star and a normal Sun-like star (upper left). Using data from the European Space Agency's Gaia mission, astronomers found several systems like this one, in which the two bodies are widely separated. Because the bodies in these systems are far apart, with separations on average 300 times the size of a Sun-like star, the neutron star is dormant—it is not actively stealing mass from its companion and is thus very faint. To find these hidden neutron stars, the scientists used Gaia observations to look for a wobble in the Sun-like stars caused by a tugging action of the orbiting neutron stars. These are the first neutron stars discovered purely due to their gravitational effects.
