Over the past decade, scientists have discovered a wonderful trend: Radio pulses are coming from inside our skying galaxy, which is pulled every two hours every two hours like a cosmic heartbeat. Long radio blasts, which continued between 30 and 90 seconds, appeared to come in the direction of the big tower, where the Big Deper is located.
Now, astronomers have zero the amazing origin of extraordinary radio pulses: a dead star, called a white dwarf, which is wandering around a small, cool red dwarf star. Red dwarf is the most common type of star in cosmos.
These two stars, known as ILTJ1101 collectively, are closely wandering each other so close that they are interacted in their magnetic fields, which eliminates that long -term radio is known as temporary, or LPT. Earlier, the long radio burst was tracked only neutrons stars, the dense remains were left after a magnificent explosion.
But this discovery is described in a research published in the journal on Wednesday Nature astronomyRefers to the movement of stars inside a wrap pair, rare LPT can also form.
“We have set up for the first time, which stars produce radio pulses in a mysterious new class of ‘Long Period Radio Transit’.
Astronomers say that unprecedented observations of such bright, long radio bursts from this binary star system are just the beginning. This discovery can help scientists better understand what kind of stars are capable of producing and sending radio pulses across the universe – and in this case, two stereotypes show the history and dynamics of stars.
To solve the mystery of the sky, de -Writer devised a way to identify a network of radio telescopes throughout Europe for less frequency array telescope archives, or for seconds to seconds from the archives of the inflamed. This is the largest radio array that works on the lowest frequency of the land.
De Writer, who developed his method while being a doctorate student at Amsterdam University, was exposed to the same pulse of 2015. Then, focusing on the same patch of the sky, he received six more pulses. They all started with a fainted red dwarf star. But De Writer did not think that the star could prepare the radio waves itself. Something else had to incite it.
The pulses are different from the sharp radio burst, which are incredibly bright, the mills of radio waves shine longer. “Almost all the FRB starts from outside our galaxy, and when some of them are repeated, many people appear once,” said Writer. Radio radio bursts are also very luminous.
“Radio pulses are very similar to the FRB, but each of them varies,” said North Western University’s Center for Inter -Discipline Exploration and Research, in astronomy, Research Assistant Professor.
“Pulses have very little energy than FRB and usually last for several seconds, as is the last millions of FRBs, which is in the last hundred seconds. There is still a big question whether there is a continuation of the items between long -term radio transit and FRB, or if they are a separate population.
De Writer and his colleagues conducted a 21-foot (6.5 m) in the MMT Observatory at Mount Hopkins in Arizona using a multiple mirror telescope, as well as the Red Dwarf Star’s follow-up observations, as well as the McDonald’s Observatory in the Davis Mountains in Texas.
Kill Patrick said observations show that the red dwarf is moving forward, and its movement is similar to two hours between radio pulses. The back movement was due to the gravity of another star on the Red Dwarf. Researchers were able to measure the motivations and to calculate a massive account of fellow stars, which they vowed to be white.
The team learned that the two stars, located 1,600 light years from the ground, were joining together when they turned around a common center of gravity, and completed a orbit every 125.5 minutes.
The research team believes that there are two possible causes behind the pulses. Either the white dwarf is a strong magnetic field that releases pulses as usual, or the Red Dwarf Star’s magnetic fields and the orbit of white dwarf.
The team plans to observe the ILTJ1101 and study any ultra -violet light that is coming out of the system, which can further reveal how the two stars have spoken in the past. De Writer also hopes that the team can observe the system in radio lights and X -rays during the Plus event, which can highlight the interaction between the magnetic sectors.
“At that time, the radio pulses disappeared completely, but it will withdraw from the later time,” said De Writer.
The team is also combing through the data data in search of other long pulses.
“We are starting to find some of these LPTs in our radio data,” said Dr. Costobh Rajwada, a radio astronomer at Oxford University. “Every discovery is telling us something new about the most astronomical physics that we can see.”
Other research group In the past few years, 10 long systems have been found to eliminate radio plus, and they are trying to determine what they are created because pulses, all of them start from Akashinganga, “said De Writer.
In contrast Natasha Herley Walker, a radio astronomy and associate professor at the International Center for Radio astronomy Research in Australia, said that the short burst made by the Pulseer, or the fast -moving neutron stars, can stay anywhere for a few seconds. Harley Walker was not involved in new research.
“Reading, temporary sources of radio have encouraged some of the most interesting discoveries in astronomical physics: the discovery of Pulseer and the discovery of neutrons stars, the FRB’s discovery, which has otherwise the ability to measure the hidden matter between galaxies, and we have only exploited the ability to measure it. “The interesting thing for me is that now that we know that these sources are, we are actually looking for the historical figures that have been behind for decades – they were hiding straight.”
He said that scanning the sky with powerful radio telescopes would only produce more incredible results.
“The biggest potentially whistle will be discovered by the whistle,” Harley Walker said of the gestures created by Intelligent Life. ”
