Only when astronomers believe that they have begun to understand astral activity, something strange draws their attention. This is the case with a newly discovered star called Askap J1832-0911. It is located about 15,000 light -years from Earth and belongs to a category of stellar things called “Long Radio Transient”.
This means that it emanates from the radio waves that differ in its severity on a table of only 44 minutes for each session. It does the same thing in the severity of X -rays, the first time that anyone has seen such a thing associated with long radio lifetime, reports. www.universtode.com.
Why does it differ in both the X -ray and X -rays like that? Knowing that ambiguity is the function of Dr. Zeneg Wang from the University of Curtin in Australia and a team of astronomers. Wang said: “Astrologists have looked at countless stars with all kinds of telescopes and have never seen one working this way.” “It is interesting to see a new type of behavior for the stars.”
However, Askap J1832 (briefly) is exhibition even strange behavior. Using Chandra and SKA Pathfinder, the team found that it also decreased in X -rays and radio waves significantly over six months. So, what is happening there?
What causes Askap J1832 emissions?
Big questions focus about this strange being about what it is and whether his behavior gives evidence of the story of its origin. Is it a typical of long -term radio transit? “We have looked at many different possibilities that include neutron stars and white dwarves, either in isolation or with accompanying stars,” said Dr. Nanda Raya of the Barcelona Space Science Institute. “Until now, nothing is matching completely, but some ideas work better than others.”
The science team examines some possibilities, but it is not quite sure that the beating star or the neutron star is located in the heart of ASKAP J1832. The beating has a varying intensity in its emissions.
This is because it is wonderful residues, I left a catastrophic event called the Supernova explosion, which represents the death of a huge star. The essence of the star is all that remains, and it rotates very quickly. It gives radiation, which appears as a vibrant sign as the object rotates several times per second.
The neutron star, also the residue of Supernova explosion, is not a good explanation as well. When such an object is with a partner star, its weight will absorb materials away from the partner star.
This procedure causes contrast in the severity of emissions as well. However, the research team does not believe that such a husband explains Askap J1832 because the intensity of radio emissions and X -rays does not match what these creatures usually give.
The team also does not think that it is a magnetic, a strong magnetic star, a neutron star. The magnet is usually very old, and some signs of ASKAP J1832 are not typical, too.
The only possibility may be a white dwarf with a accompanying star. These diodes often give radio emissions and X -rays that can fit with the description of what Chandra and SKA tools have seen. However, to make this work, the white dwarf will need an incredibly strong magnetic field – something that astronomers have not yet seen.
Askap J1832 does not appear in the same field as the Supernova residue. It is unlikely to be associated, and it may be just a state of chance.
So, what is this?
In the end, scientists did not discover the reason for the Askap J1832 caused such changes in the severity of emissions. It can be a completely new version of the objects they already thought. More notes are needed for her relationship.
Besides notes with Chandra and SKA, this area of space was also studied by The Swift, which is a very large group, the Australia Telescope Compact, the giant Metrewave radio telescope, Meerkat, and other facilities.
Each of these observations has seen density differences and helped create the basis timing of explosions. However, at the present time, astronomers are still trying to put what they have seen in models that will help them set an origin and interpretation of emissions.
“We will continue to search for evidence about what is happening with this object, and we will search for similar things,” said team member Dr. Tong Bao of the Italian National Institute of Astronomical Physics (INAF) – the Great Astronomical Member in Italy. “Finding a puzzle like this is not frustrated – it makes science exciting!”
