So, my understanding is that the Simp is all alone?

Being that size can be really fucking intimidating to others.
SIMP? More like PGTOW (Planets Going Their Own Way)
This planet is no orbiter.
I hate that I laughed at that
So, my understanding of auroras is, the planet's magnetic field draws particles emitted by the sun toward the poles, and as those particles interact with the atmosphere they glow. So without a star and thus without solar wind, where do the aurora come from?
I mean, it has a magnetic field 6 or 7 orders of magnitude higher than ours. Id guess that extra strength allows it to pull particles from much further away and possibly from sources much more reticent to give up their particles than solar wind
Both the magnetic field strength and charged particle flux fall off proportional to the square of the distance from the planet / star respectively, so I doubt it gets much of anything even with a strong magnetic field unless it’s also near a star.
I’d also point out that the particles aren’t really attracted by the earths magnetic field, we’re just in the pathway, and the magnetic field funnels them to the poles. It’s more guidance than attraction.
If the rogue planet is truly all alone in space, you're definitely right. 4 million times is a lot, but space is really, really big, and solar radiation falls off with 1/r^2.
Let's assume the auroras are proportional to the size of the magnetic field. That's probably not true, it's probably actually proportional to the square root of the magnetic field because field strengths fall off with 1/r^2, but let's give it the best possible chance of having huge auroras. That would mean that a planet with 4x the magnetic field of Earth would have the same Aurora brightness at 2x the distance. So, something with 4 million times the magnetic field would have the same brightness at sqrt(4,000,000) the earth-to-sun distance, or 2000x the distance. If it were in our solar system, or even just near our solar system, it would be bright. But, space is big.
Since the earth is about 500 light-seconds from the sun, 2000 earth-distances is about 1 million light seconds, or about 11.5 days. By comparison, the closest star to Sol is Proxima Centauri at 4 light years. So, these Auroras would only be earth-like if the rogue planet were very close to some star. It wouldn't have to necessarily be in orbit of that star, but it would have to be pretty close. If it were out in the space between the stars, there's just nothing there for the magnetic field to interact with.

Im guessing it only occurs when it is in a cloud or trail of charged particles. or perhaps there is a local (climatic?) cycle that sends charged particles to the poles.
The Wikipedia linked in these comments says it is likely from electron precipitation. Basically the magnetic field traps free elections and thus "wiggles" as they interact with the field. This can make a (pulsed) radio jet shooting from the pole, which is how this planet was observed. These electrons can fine from atmospheric phenomena such as lightning or large storms.
Earth has the same but much weaker phenomenon, the Van Allen belt, which was a difficult challenge to handle in the early days of space exploration.

wtf,they have several classifications.
- free-floating planetary-mass object
- exoplanet
- rogue planet
- brown dwarf
welcome to science where theres names, AND acknowledgement that things change with new data
Strangely attracted to distant stars yet unable to establish a stable orbit, Simp 0136 is condemned to a lonely existence.

Strangely Independent Massive Planet - Simp
wait is this real or a joke? do we have a new planet that I've never heard of??
This planet isn't in our solar system. We've found 6,053 exoplanets already, so it's a safe bet that there's lots more of them than you're aware of
We have discovered over 6000 exoplanets in total, and over 100 in this year. I'd be surprised if you knew of all of them
Oh you wanna be an astronaut, kid? Name every exoplanet

Galaxy, not Solar System. There are a lot of planets in our galaxy that you’ve probably never heard of

Interesting, I just finished reading Rendezvous With Rama.
If a massive object like that was to pass through our neighbourhood I think it could fling planets out of the solar system.
Even with this mass this planet would have to pass one of the outer planets extremely close and quite slowly to have a chance of dragging a planet out of the solar system.
This is the same sort of idea as when galaxies merge. There is little chance of our solar system being effected in that scenario. There is just too much space to space.

That's one of my very favorite books. It's fantastic at setting the mood. The further books are ok but not as much to my taste.

Ofc the simp is cucked in the corner not allowed to join the orgy of planets.

Borg Sphere Model 2025
So how come there's an aurora when there's no star to spray it with electromagnetic radiation?
Because the planet produces its own radiation. That much mass means this is less a "planet" and more of a proto star. It's actually large enough to fuse deuterium if the right conditions arise. Pour enough hydrogen in there to raise the mass three of four times what it has now and it'd be comparable to our sun.

Likely a brown dwarf or magnetar
Looks like a brown dwarf, especially from the Wiki page
I was going to say, I read somewhere at uni that if Jupiter was 14 times as large, it would have become a brown dwarf.
Name seems wrong but you do you, SIMP 0136
Lonely queen.
Welcome to 2016. Mike brown and Konstantin Batygin basically proved that the only way we could explain the orbits of Pluto and other KBO was a massive 9th, yet to be discovered rogue planet more than likely ejected from our inner solar system during planet formation.
He's just jealous 'cause the dorks on Earth called him a failed star.
Simping for magnetism
My new band name
That's looks like a picture of Jupiter, or an artists impression of it, and there's a star needed for an aurora to happen.
Any scientific sources to back this story up?
No it is indeed an artists impression of the planet - it's on the wiki page.
I'm assuming that aurora only needs solar wind to happen on earth - or that solar wind outside the heliosphere is strong enough you don't need a star for it to happen.
In 2018 astronomers said "Detecting SIMP J01365663+0933473 with the VLA through its auroral radio emission, also means that we may have a new way of detecting exoplanets, including the elusive rogue ones not orbiting a parent star ...
