Astronomers have found a star just 33 years old


A team of astronomers have observed that they believe a neutron star was born after a supernova, first detected in 1987, in a satellite galaxy 170,000 light-years from Earth called the Milky Way SN 1987A .

Until now, astronomers were not sure if the neutron star had survived the powerful event and had not set itself up to create a black hole – but a new paper published last week The Astrophysical Journal The suggestion is that it may survive after all.

This means that the neutron star will be one millennium, not exceeding 33.

If confirmed, it would be the lowest neutron star known to mankind, as Astro Report. To date, the youngest supernova remnant is 330 years old Cassiopeia A, about 11,000 light years away from Earth inside the Milky Way.

Analyzing high-resolution imagery from the Atacama Large Millimeter / Submillimeter Array (ALMA) in Chile, a team of astronomers were able to take a closer look at what was left after following SN 1987A.

They found a hot “blob” inside the core of the supernova, a possibility that a cloud of gas would erupt from the neutron star. This star in itself will be very small, which can be directly detected, because it is very small and dense – 1.4 times the mass of the Sun within a sphere that is only 15 miles across.

Mikako Matsura of Cardama University said in a statement with ALMA, “We were very surprised to see this hot drop made of a dense cloud of dust in the supernova remnant.”

The discovery by the ALMA team supports the new theoretical study published last week.

“There must be something in the cloud that warms the dust and shines through it. So we suggested that there is a neutron star hidden inside the dust cloud, ”said Matsura.

“Despite the supreme complexity of a supernova explosion and the extreme conditions of reign in the interior of a neutron star, the detection of a hot drop of dust is corroborating many predictions,” lead author Denny Page, Astrophysicist University of Mexico at National Autonomous, in statement Has been explained.

According to the computer model, the neutron star would have been sent screaming into space at the rate of hundreds of kilometers per second. According to the model, the place the ALMA team found it is today.

The theoretical star was also found to be very bright, thanks to its assumed temperature of about five million degrees Celsius.

This will take time until the existence of the star is confirmed. The dust and gas around the supernova need astronomers to say with any certainty that the extremely young star actually exists.
