It is massive, magnetic it even creates its own light show. One tricky weird planet without a star, wander on the Milky Way and it’s only 20 light-years from our sun. According to recently published research in The Astrophysical Journal, this weird, nomadic world has an incredibly powerful magnetic field. The planet’s magnetism is around 4 million times more powerful than the planet earth. Surprisingly, the exo-planet seems to generate astonishing radiance auroras, that could surpass our northern lights.
The new observation, made by Carl G. Yanski from the National science foundation says Very large Array (VLA), not only the first radio observation of the object with planet mass beyond our solar system but also mark the first time of which the scientists measuring the magnetic field of such object.
Sizing up the SIMP
The specific and independent object, for short SIMP Jo1365663+0933473 ( we will call it SIMP for simplicity reasons) It was found for the first time back in 2016. At the time the astronomers thought that the SIMP is just a brown dwarf: An object that is too big to be a planet, but too small to be a star. Last year, another research showed, that SIMP is small enough, with 12.7 times the mass and 1.2 times the radius of Jupiter, to be considered as a planet- albeit a mammoth one.
“This object is exactly on the border in between a planet and brown dwarf” unsuccessful star “And it gives some surprises, that potentially could help us to understand the magnetic processes for the starts and for the planets”, says Melody Kao, government university in Arizona, that operates new research for SIMP, in a press release.
For a planet, SIMP is also too hot
The world has a surface temperature of 1500F+ (825 C). For comparison, the hottest planet in our system is Venus, which sport an average temperature of 875 F( 470 C). While the sun, is a small and cool star, there is a surface temperature of 10 000F ( 5500C). It is important to notice, that Venus gets most of its heat from the sun. Since the lonely SIMP does not orbit around a star, the heat must remain from the very first formation of around 200 million years ago. So in a time period, the planetary Goliath will remain to radiate its own heat.
According to the last research, SIMP is not just giant for the planet standards but it has a magnetic file, which is a million times stronger than the one on our planet. Despite this magnetic field helps SIMP to create Astonishing light shows, the polar lights are not generated in the same way as here on Earth.
Jupiter has the most powerful magnetic field in our solar system. Almost 20 000 times stronger than earth’s one. Jupiter’s field produced incredibly bright polar lights. That is happening, when positively electric particles are accelerated on the lines of the magnetic field of the planet, before crashing in the atom of the upper part of the atmosphere of Jupiter with around 3 000 miles ( 5 000 kilometers) а second.
On earth, a similar process is producing the thing that we called northers and Southern lights, but the charged particle, that leads to the polar lights of Earth, arriving mainly from the sun, under the form of the solar wind. On Jupiter, their charge particles are arriving mainly from its moon, instead of the solar wind. Since Simp does not have a star to bomb with the wind, as here on Earth, the Astronomers speculates, that the light of SIMpe might be produced in the same way as Jupiter, which means that SIMP might have a moon.
To summarize: SIMP looks like a massive and magnetic exoplanet without a star, that could have a moon, and generate bright lights while wandering around the Milky Way.
Whoa! That’s amazing. But how this amazing find will help Astronomers to learn more about the universe?
“This specif object is intruding since its research about his magnetic and dynamo-mechanism can give a glimpse of a new perception of how the same mechanism can work for Solar-free planets”, says Kao. “We think that these mechanics can work not only in the brown dwarfs but in the gas giants and in the Earth-planets like”
In other words, SIMP will help Astronomers to get a better understanding of how magnetic fields of the Exoplanet are generating. But wait that’s not all!
The discovery of SIMP J01365663+0933473 with VLA through their Auroric radiation also means, that we have a new way of discovering exoplanets, including untraceable scammers, that do not orbit a parent start” claiming co-author Greg Holian.
And so, there it is. SIMP is an Incredibly interesting object alone, but the most important thing is that this study opens the door for future perceptions in our exoplanetary magnetic field, and polar lights. Also a helping tool in looking for other Exoplanets that seems like their personal life.
