Astronomers are observing the fastest stellar explosions in history.
They saw a white dwarf “steal” gas from a nearby red giant, causing one of the largest explosions ever seen.
“Nova” was bright enough to be seen around the world with binoculars.
It was over in a day, three times faster than anything else.
Matter was launched into space at speeds of millions of miles per hour; this is observed as visible light.
Named V1674 Heracles, it disappeared after being visible to the naked eye for more than 24 hours.
It is about 100 light years from earth and you can see the world with binoculars. The incident occurred on June 12 last year.
“It was as if someone turned the flashlight on and off,” said lead author Professor Sumner Starfield of Arizona State University in the United States.
November is different from a supernova. They are found in star systems: small, incredibly dense stars and much larger sun-like companions.
Gas emanating from the latter flows in a spiral over the surface of the former, like water in a bathroom drain.
Under heated and compressed gravity, hydrogen fuses and explodes, like a thermonuclear bomb.
Professor Starfield said: “It was just one day, and the fastest nova in history was what we learned in 1991. V838 Herculis subsided in a few days.”
This research sheds new light on the chemistry of our solar system, the death of stars, and the evolution of the universe.
His speed was not his only unusual characteristic. The light and energy sent out also pulsates like the sound of a bell.
Every 501 seconds, there is a noticeable vibration in visible light and X-rays. It still exists a year later and will last even longer.
Mark Wagner, Chief of Science at the Large Binocular Telescope Observatory on Mount Graham in southern Arizona, said:
But it also became clear when the nova was 10 orders of magnitude brighter. The secret people are trying to tell you is to see it in system brightness at this range.
The US team also noticed a strange wind as they watched Nova drop the issue. It may depend on the position of the white dwarf and its companion.
They appear to form a material flow in space around the system in the constellation of Hercules.
It is in a very convenient location and the twilight disappears as it sinks into the dark eastern sky.
It’s less than 17° north of the celestial equator, so you can see it from anywhere in the world and shoot in just a few seconds.
The new star gives us important information about our solar system and the entire universe.
Only 10 were found during this period, but it is estimated that between 30 and 60 deer jumps occur each year. Most are covered in interplanetary dust.
White dwarfs collect and transform matter and disinfect the surrounding space with new materials.
This is an important part of the material cycle in the universe. The material downloaded by Novas will eventually create a new star system.
Such events also contributed to the formation of our solar system, convincing us that the Earth is more than just carbon.
Professor Starfield said: “We are always trying to understand what the solar system is like and where the chemical elements in the solar system come from.
“One of the things we’re trying to learn about this new star is, for example, how much lithium was produced as a result of this explosion.
“We are now convinced that a significant part of the lithium on Earth has been formed as a result of these types of explosions.
White dwarfs do not lose all the material collected during a nova explosion, so the mass can increase with each cycle.
This will eventually lead to instability, and the white dwarf may form a type 1a supernova. This is one of the brightest phenomena in the universe.
Each type 1a supernova reaches the same level of brightness and is therefore known as a standard spark plug.
Professor Charles Woodward, a co-author from the University of Minnesota, said:
By looking at how the brightness of light changes, we can ask questions about how the universe speeds up, or about the entire three-dimensional structure of the universe. This is one of the interesting things that we’re learning about some of these systems. “
Also, novae will tell us more about how binaries evolve before they die. This is a misunderstood process.
They also serve as a living laboratory where scientists can see the real world of nuclear physics and test theoretical concepts.
Nova surprised the world of astronomy. He was not on the radar of scientists until the wise Japanese amateur astronomer Ueda discovered and reported him.
Citizen scientists are playing an increasingly important role in the fields of astronomy and modern technology. ]
The Nova listed in the American Astronomical Society’s research records is so faint that it cannot be seen with other types of telescopes.
But still, thanks to its wide aperture and modern scanners, it can be monitored with the Large Binocular Telescope.
Professor Starfield and his colleagues are trying to investigate the cause, the process that caused it, the reason for the record decline, the force behind the observed wind and the pulsating brightness.
