NASA’s Chandra X-ray Observatory and its NuSTAR (Nuclear Spectroscopic Telescope Array) have indirectly discovered what he thinks is the remaining stellar heart of Supernova 1987A, the first naked-eyed supernova found there more than 400 years. Located in the nearby Magellanic Cloud, a dwarf galaxy located about 170,000 light-years away, Supernova 1987A (or SN 1987A) was first seen from a lone Chilean mountain portrait on February 23, 1987.
In a paper published in The Astrophysical Journal, an international team of astronomers notes that, after three decades of research, they have used x-ray scattering to detect the heart of the supernova neutron star. The team also used data from Chile-based Atacama Large Millimeter Array (ALMA) to support their claims.
“For 34 years, astronomers have been sifting through the 1987 1987 stellar debris of SNA to find the neutron star we expect to be,” Emanuele Greco, of the University of Palermo, Italy, said in a statement. “There have been a lot of ads that have been put to death, but we think our latest results could be different.”
These objects have been called neutron stars, because they are made almost exclusively of packaged neutrons, NASA says. Fast-changing, highly magnetic neutron stars, called pulsars, emit a beam of lighthouse-like radiation that astronomers detect as pulses when their orbit is swept away. the behavior across the sky, the space agency observes. However, there is a subset of pulsars, NASA says. which carries winds from their surfaces – sometimes at almost the speed of light – creating complex structures of charged grains and magnetic fields known as “pulsar wind nebulae.”
NASA says the most likely explanations for this volatile X-ray emission are that it is emitted by just a pulsar wind nebula.
What kind of supernova explosion created such a neutron star?
The most likely condition involves heart failure supernovae. Supernova transmitters are big stars of a falling heart that falls apart at the hearts of the iron. That is, when the star’s nuclear material cannot support the star’s weight.
In fact, SN 1987A provided the first direct confirmation to astronomers that heavy elements are produced in supernovae.
SN 1987A is known as a subsequent Type II heart failure supernovae left after a complex remnant, either a neutron star or a black hole, as I noted here in a previous post. But in the case of SN 1987A, there is still some debate as to whether the explosion was caused by two stars combined.
Astronomers have long known that the 1987A light loop carried a strange light from the exit. For one reason, it has never gotten as clear as a normal heart failure supernova, which is why it is officially classified as a Type II ‘Peculiar’ supernova. That means it just doesn’t fit into any of the known type II fall subdivisions.
As for the progenitor star of the supernova?
Sanduleak -69 202 is known to be at least one of its promoters, a blue star of some 20 sun masses. Whether the explosion at the heart of the supernova was caused by the collapse of one giant blue star or caused by the union of two stars remains open to debate.
But NASA believes that if a pulsar is indeed at the center of the remains of a 34-year-old supernova, this is the youngest one ever discovered. As a result, it will therefore be ideal for seeing improvement.
It is hoped that the stellar debris will spread around the putative pulsar over the next few years. If so, NASA says that in about a decade, the pulsar’s emissions will appear unobstructed, indicating the formation of this recently formed spinning neutron star.
