It was even visible toNaked: Scholars report in a report from Discovery The fastest ever! That was just over a year ago: it appeared in the sky on June 12, 2021, and then faded away just a day later. “It was only one day; the fastest previous nova was the one we studied in 1991, the V838 Herculis, which faded away in about two or three days”explains Summer Starrfield, the professor and at the ASU School of Earth and Space Exploration.

Usually, such events last between a week to a few months. these It appears in the sky as new hence the term Nova who was chosen to appoint them.

It corresponds to a sudden and intense emission of white light
Visible light has wavelengths from about 380 nanometers (violet) to 780 nanometers (red).

The latter is actually the remains of a dead star: white dwarfs that are created after Not too bulky, when you run out of fuel. Then it goes through a phase Where the upper layers extend. Then its outer layers pop out, leaving only the core of the star, which is compressed and transformed into a white dwarf.

As the material twists and turns as it moves toward the white dwarf, it forms an accretion disk. Inside this disk, the material is so intensely heated, that it turns into plasma, and thus into ionized. This ionized gas heats up. Much.

We are now fairly certain that a large portion of the lithium found on Earth resulted from these types of eruptions. »
In addition to its speed, the researchers note another property: the light and energy we receive from the V1674 Herculis pulse. Every 501 seconds a visible oscillation occurs both in the visible range and in the 1895 invented by Wilhelm Röntgen

Even today, a year later, this pulse continues, always with the same regularity. “The most unusual thing is that this oscillation was observed before the explosion, but it was also present when the nova was brighter, about 10 degrees.”Explains Mark Wagner, a researcher at Ohio State University. In the future, the team intends to look into the cause of the explosion, so the processes that lead to a big explosion Similar to this, especially with regard to the case So short.
