For the first time, scientists have observed the removal of CME coronary masses on the surface of distant stars.
So far, astronomers have only seen the initiation of coronal masses arising from our own sun, but the data collected by Chandra shows NASA a powerful torch erupted from the surface HR 9024, a distant star.
During the investigation of Chandra’s data, astronomers identified X-ray explosions followed by large plasma radiation.
“The technique we use is based on monitoring the speed of plasma during eruption stars,” said Costanza Argirofi, an astronomer at the University of Palermo in Italy. “This is because, in analogy with the solar environment, it is expected that as long as the plasma flame is in the position of the first closed coron combustion contour moves up and then to reach down, the lower atmosphere layer is another Movement Sternes, always up, because CME is related to torch, expected. “
HR 9024 is a rotating variable star in the constellation Andromeda. The distance is about 450 light years from Earth. Scientists identify torches with promising properties. The astronomy team used the Chandra high-energy transmission spectrometer to measure plasma movements associated with flashlights.
Their measurements show the movement of extremely hot star material – in sizes from 18 to 45 million degrees Fahrenheit – at speeds of 225,000 to 900,000 miles per hour. The first plasma enters the star’s atmosphere and then dives back into the star’s surface.
“These results, which are unmatched, confirm that our understanding of the fundamental phenomena that occur in fire is solid,” Argirofi said. “We are very confident that our predictions in such a way can coincide with observations, because our understanding of torches is based almost exclusively on observing the solar environment, where the most extreme outbreaks of X-hundred broadcasting are even less intense.”
Scientists have published their observations this week in the journal Nature Astronomy.
“The most important point of our work is different: we found that after the coldest plasma torch -” only “seven million degrees Fahrenheit – rose from a star at a constant speed of around 185,000 miles per hour – said Argirophy.” And the numbers were exactly as expected from CME in the context of a torch. “
While new discoveries have produced bigger stars, younger stars, bigger stars, and stronger CME, the researchers hope the plasma will move at higher speeds. Lower levels indicate that the electromagnetic fields of active young stars are less effective in pushing plasma in the atmosphere.
