‘Shocking’ Nova explosion in Dead Star 100 times brighter than the sun

In the first study close to a recurrence of a repetitive repetitive corridor outside the dairy corridor, astronomers have discovered high temperatures and unexpected chemical signatures, indicating an intensive and special explosion.

The Nova explosion occurs in a semi-semi-different dual system that contains a cool, cold star and a white dove.

“A white heat star, almost the size of the Earth, but the presence of mass compared to the sun, siphones from materials from its cool friend,” Nai Evans told Space.com. “The material that accumulates from a cool star on the surface of the white pigeon and eventually explodes in a hot nuclear fugitive. This is a Nova explosion.

Most of the Novas have been seen once exploding, but have been seen several times that explode several times. These are known as repetitions, with the distance between the explosions from just one year to decades.

“When the explosion decreases, the siphoning starts on all sides and another hot heat explosion occurs in time, etc.,” Evans said.

Less than dozens of repetitive Novas are identified in our galaxy — are mostly known outside the Milky Way, mostly in the Androme galaxy (M31), and four of the Magelan clouds (LMC).

know one of Nova abnormalities

Nova LMCN 1968-12A (LMC68), located in LMC, was first seen in In 1990, he was seen again in the explosion, making it the first Nova to be seen again outside the galaxy, with the appearance of four years.

“In systems such as LMC68, less mass from the Nova explosion exceeds what is obtained by transmission from the cooker,” Evans said. “This means that the mass of the white pigeon is increasing constantly. In time, it approaches an important value… above the white pigeon can not support its weight, and it explodes, which results in a Supernova explosion.

After the 2020 bombing, NASA has been monitoring the LMC68 for months, predicting the next explosion in August 2024.

“The LMCN 1968-12A is about 50 times higher than the Nova explosion in our milk galaxy, and here is about 2,500 times,” Evans said. “You must use the largest telescopes of being (to see, and) you must reach them as soon as they explode; so you destroy other surveillance programs.

“He is very well willing because there are no big infrastructure telescopes.

Chemical ingredients analysis of a unique Nova

With infrared red lights near LMC68, for the first time, astronomy teams were able to investigate very hot stages, when many elements have a lot of energy. This gave a valuable view of extremist forces that hit the Nova explosion.

They did this using Spectroscope, a technique to analyze the length of different waves of light absorbed and out of the time of the explosion.

This allows them to identify the chemical elements that are willing to and understand how they are affected by the heat of Nova, which generally “ion” or arouses the atoms, which causes their electrons to jump to higher energy levels before returning to their initial situation.

“Remotion lines are formed when an atom or an ion is calmed down from a high energy situation to a lower energy situation,” Evans said. “The difference between energy appears as a photon of infrared light that is a unique sign of atomic or ion. We know what the stars are made of.

“While other similar Nova researchers generally revealed signatures from different elements known as “mines” (which, astronomy, any other element other than hydrogen or helium, although a chemist may have something about it), the team was surprised to know LMC68. Signals from Slicons from Sliks in Sliks in Slikes in Slikes in Slikes is an infinite amount of energy.

“The silicons that shine about 100 times the sun are unprecedented,” Tom Gibal, an astronomer without Emerets, said in a statement. “And it shocks this signal, but it shocks it that it is not there.

“We were expected to see the signatures of too much energy, phosphorus, calcium and aluminum.

The team suggests that high-level density of electrons inside the Nova area could cause expansion atoms to lose energy through collisions rather than exposing light. But this is a possibility, but it does not explain why the ordinary synthetic lines that are generally seen in the light of a repeated Nova are completely uncommon.

This shows that something unusual happens with LMC68 that is different from the normal Nova.

LMC68 is different from the repetition of a galaxy because the star of his friend is likely to have less metals, which means a lower amount of heavy elements, which is specific to LMC. Mineral stars can lead to a stronger Nova explosion, because more substances need to start.

While the lack of secondary minerals can affect the Nova structure, it does not explain the complete lack of metal line under close red. The explosion still processes material through normal heat fugitives, but the signing of the expected metal is no longer.

Club rising wreaths at 5.4 million degrees Fahrenheit (3 million degrees Celsius) in LMC68 may give a sign. Heights of wreath gas can lead to a process called collision ions, in which the atoms in the gas are more ions, more than normal, ie they lose more electrons and reach higher energy.

“To delete nuclear or ions, many electrons need to enter energy,” Evans said. “In the ions of collisions, the energy is supplied by fast electrons that collide with the atoms/INN, give them energy to that level.

This means that the ions that are particularly seen in the crown stage of other Novas are less in their “normal” forms, because they are pushed into these high states.

The fact that the LMC68 gas is a mineral deficiency, which means that it contains fewer elements such as magnesium and calcium than normal stars. When the gas passes through the nuclear flight process (the explosion in Nova), the lack of these elements increases, causing a sharp decline in the remnants of the explosion.

This structure – which is high temperatures and deficiency of minerals – can explain why the mineral lines were not in the current monitoring.

“Only a small number of repetitive Novas found in our galaxy, understanding these things are advanced in an epidemic,” Martin said. “By expanding our distance to other galaxies by using the largest astronomical telescope available, like Jimin South, astronomers increase the rate of progress and critically measure the behavior of these things in different chemicals.

While it’s an interesting theory, the team emphasizes the need to model research to measure the products of these reactions and more notes by using the length of longer light waves to confirm the assumption.

The team’s research was published in the monthly journal of the Royal Association of Astronomy.
