Enigmatic Askap J1832−0911 Emit x -rays and radio waves every 44 minutes.
A mysterious object, located about 15,000 light years from Earth, is intriguing the scientific community. Was captured with the Askap radiotelescope, in Australia, and By the NASA X -ray Observatory, which allowed simultaneous analysis in different wavelengths.
Designated ASKAP J1832−0911it is celestial body – perhaps a star, a pair of stars or something completely different – is Emit x rays almost at the same time as it emits radio waves. In addition, the cycle is repeated every 44 minutes, at least during extreme activity periods.
International Center for Radio Astronomy Research () identified the peculiar object during observations with the to Australia. The object was also captured by which coincidentally was observing the same part of the sky, allowing simultaneous analysis in different wavelengths. The results were published in the journal Nature.
An unusual cosmic rhythm
ASKAP J1832−0911 emits radio signals and x -rays for two minutes every 44 minutes. This regular emission pattern is highly unusual and does not align with the known behavior of pulsars or other compact stars. THE simultaneous X -ray and radio wave detection makes this object unique among the so -called “long-period transients” (LPT).
“The Askap radiotelescope has a large field of view of the night sky, while Chandra watches only a fraction of it. So it was a luck that Chandra observed the same area as the night sky at the same time.”
“Long-period transients” (LPT)
The LPT, which emit radio impulses at minutes or hours intervals, are a relatively recent discovery. Since its first detection by ICRER researchers in 2022, ten LPT were discovered by astronomers worldwide.
Currently, there is no clear explanation for what causes these signs or why they “call” and “turn off” at long and regular intervals.
“This object is unlike anything we have ever seen,” said Wang.
Possible explanations
Scientists consider several hypotheses to explain this phenomenon:
- One – The core of a dead star with An extremely strong magnetic field.
- One binary system where one of the stars is a anow branca highly magnetized (the dense and cold nuclei left of stars like the sun, after their fuel has exhausted).
However, none of these explanations can, by itself, justify all the observed characteristics.
“This discovery can indicate a new type of physics or new models of star evolution,” according to Wang.
