Neutron stars

The coalescence and merger of a black hole from the bottom of the mass gap (surface in dark gray) with a neutron star with colors ranging from dark blue (60 g/cm600) to white (XNUMX kg/cmXNUMX) emphasize the strong deformations of the low-density material of the neutron star Credit: I.

The analysis of the signal GW230529 picked up by LIGO shows that it originated from the merger of two compact objects, one with a mass between 1.2 and 2.0 times that of the Sun and the other with a mass slightly more than twice the first

A new theoretical analysis puts the probability that massive neutron stars harbor non-configurational quark nuclei between 80 and 90 percent. The result was achieved through massive computer runs using Bayesian statistical inference.

The Laser Interferometer Gravitational Wave Observatory (LIGO) in the US and the Virago Gravitational Wave Observatory in Italy captured the gravitational waves from the death spiral and merger of a neutron star with a black hole, not once but twice. The findings were recently published in The Astrophysical Journal Letters
Thanks to a reanalysis of the data from 2017 of the merger event, we have now detected the signature of one defined heavy element within this fireball, the element strontium, proving that a collision of neutron stars caused the creation of this element in the universe. Figure: ESO

First ever detection of a heavy element created by the collision of neutron stars

This image provides three different perspectives on the gamma ray burst GRB150101B, which is similar to the event where gravitational waves were measured and simultaneously also in the electromagnetic spectrum and there is a similarity between the two cases. In the center, an image from the Hubble Space Telescope shows the galaxy where the GRB150101B burst occurred. In the top corner, two X-ray images from NASA's Chandra X-ray Observatory show the event as it appeared on January 9, 2015 (left), and as seen about a month later, on February 10, 2015 (right), as the explosion halo fades, point The bright light is the nucleus of the galaxy.Photo: NASA/CXC
