NASA discovers amazing neutron stars, this is what they look like
The astronomers who study the powerful explosions called “short gamma ray bursts” (GRB) detected light patterns that indicate the brief existence of two super heavy neutron stars shortly before collapsing black hole. The POT shared the amazing images.
This is what neutron stars look like that resist being black holes
The POT shared a simulation that tracks the gravitational wave and the density changes when two neutron stars in orbit collide with each other. The deep purple colors represent the lowest densities, while the yellow-white shows the highest.
An audible tone and a visual frequency scale (on the left of the video below) track the increase in frequency of gravitational waves as the waves approach. neutron stars. When they merge, at 42 seconds, the gravitational waves they suddenly jump to thousands of hertz and bounce between two primary tones.
The presence of these signals in these simulations led to the search and discovery of similar phenomena in the light emitted by brief bursts of gamma rays.
In accordance with Cecilia Chirentia researcher at the University of Maryland, College Park (UMCP) and the Goddard Space Flight Center of the POTthese signals were detected at NASA’s Neil Gehrels Swift Observatory, the Fermi Gamma Ray Space Telescope and the Compton Gamma Ray Observatory.
What is a neutron star and what did NASA find?
According to the POTa neutron star It forms when the core of a massive star runs out of fuel and collapses. This produces a shock wave that blows the rest of the star away in a supernova explosion.
- The neutron stars they usually pack more mass than our Sun into a ball the size of a city, but above a certain mass, they collapse into black holes.
The analysis of Compton Gamma Ray Space Observatoryas well as computer simulations related to such observations, reveal the existence, albeit fleeting, of neutron superstars with a mass and a size that clearly exceed the maximum for an object of this class.
The neutron superstars they rotate almost 1,300 times on themselves every second, almost double that of J1748-2446ad, the press (a type of neutron star) with the fastest rotation among all known. This rapid rotation is what prevents them from collapsing in on themselves the instant they form.
They survive a few tenths of a second after their birth. After that short time has elapsed, the neutron superstar collapses in on itself transforming into a black hole.
By analyzing the short gamma-ray bursts emitted in the process, the Cecilia Chirenti detected patterns of light that indicate various instances of the brief existence of a superheavy neutron star shortly before collapsing in on itself and becoming a black hole.
