""The last thing we need is a star that comes into the inner part of our solar system, starts knocking astroids around and throwing them every which way, and a giant one blasting in to the Earth.""

Sure to solve all my problems

HAHAHA

if large gas planet like jupiter has heat conviction, and unsustainable hydrogen/lithium fussion may also occure in their core, could we call them dwarf star too?

Oh, one more thing, I do think that it's a nice article as well.

Oh and to add, clearly it can't be the biggest, it is only the biggest we know about.

If it's the largest cool brown dwarf star, then does that means that they will never find any one star out there as big or bigger than that one, ever?

Could brown dwarfs have inhabitants on them ?

Yes James, we are covered by two mirror. One is on point of sun another is on the point of earthâ€™ shadow
We can see only light and lighted objects. We can see nothing in the darkness. A thing may how much bigger if it go away to away from our eye views, the thing appears us smaller to smaller and at last it will disappear from our eye views. The sun is the only object who gives light the entire solar system. In size it is 3 lakhs time bigger than earth but we look it like a football size. From calculation we know that sun is about150 millions Kilometer away from the earth. So we can find earthlike object at same distance must be disappeared. Since we are created from earth, the eyes power of us has merged with the earth. Since the earthlike object disappears at distance of 150 million Kilometer, the eye powers see anything ahead of it, is zero. But cause reflection we find very deep space on the side of darken earth and find sun spots on sun.

As far as I know, "brown dwarf" and "star" are mutually exclusive categories. Stars fuse hydrogen via the proton-proton chain, and brown dwarfs don't. (Brown dwarfs can fuse deuterium and possibly lithium at lower temperatures, but those reactions don't release much energy because deuterium and lithium are scarce.)

So "brown dwarf star" is nonsensical.

Welcome y class dwarfs .

Very Interesting,
Although 18 jupiter masses is still pretty large, I think there is even smaller waiting to be detected of the other classes.

As far as an even cooler class dwarf, Im not sure what to make of that. Whether it is even possible for that matter. Do stars require a certain internal temperature in order to jump start fusion, or is it based on mass? Or is dwarf just a term for the failed star that is to big to be a planet?

Reading that convections happen in the star, but doesn't that happen in most gas giants?

A Space Mirror? I'll grant it's a pretty looking website, but the idea seems a bit, well, shall we say problemmatic?
So if I understand your concept the earth is trapped between two mirrors, and everything we see in deep space is actually virtual depth created by reflections between the mirrors? Is this mirror a sphere? If so you have a bit of a reflection issue. If not your theory has some "gaps" in it.
I wish you luck in your efforts to $10,000 to reveal the location of the "second earth".

Since the ancestral time, world space research is progressing on wrong concept because we unknown about space mirror which is a great mystery and creator of lots of mysteries viz. milk ways, galaxies, nebulas, supernovas, white dwarfs, black holes etcs. Hence without study of space mirror the space research has no future.

It can not explain in short. Therefore it invites to visit http://www.spacemirrormystery.com to know the logic and original truth.

Mirror reflects frontier. Mirror functions like a wall. There is nothing ahead of mirror but reflection makes lively atmosphere into mirror. If two mirrors face each other in parallel position the concerned area between mirrors is converted to a biggest atmosphere because the concerned area reflected unlimitedly as front side and backside into each mirror frequently. Space mirror is based on above rule and we are unknown about space mirror. From sun the objects of area 225 million kilometer to 300 million kilometer of solar system reflects unlimitedly, we find a very deep space and through giant telescopes we watch mystery after mystery. Telescope enlarges view not closes near view. Following may clear the concept â€œA visitor of a desert often find mirage. If he moves mirage also moves. He can never reach near the mirage. If he tries he can see enlarge view of mirage as smoky atmosphere through a telescopic instrumentâ€.

Giant telescope like Hubble and others may be the milestone of our technology but it can not help the real space research.

To NNM

Hmmm… Not sure about being able to 'walk on this star'

Quite apart from the object not having a defined surface (a little like a gas giant) if it did have its gravity would squash you flat in a moment! with or without your 'little oxygen tank'!

Nice article Ian,

Any words about the internal heat source for these little brownies? If itÂ´s not nuclear fusion, could gravitational contraction account for the temperature observed? Cheers,

Hmm, 350 celcius sounds so low.
So, humans could walk on this star with anti radiation suits and quite standard anti heat equipment… + a litle oxygen tank?
I wouldn't call this a star but a gas giant in it's early stage?

To Emission:

Sorry about the confusion with my "Death Star" analogy, I wasn't thinking about the connection with the possibility of a solar partner orbiting beyond Pluto – I just whimsically used the term to describe the failed or "dead" star. In hindsight, it probably wasn't the best idea

Cheers, Ian

Well lets hope so. The whole "Death Star" theory bothers me that we havent found it yet, if it even exsist at all.

The last thing we need is a star that comes into the inner part of our solar system, starts knocking astroids around and throwing them every which way, and a giant one blasting in to the Earth.

Yes, 40AU is a bit of stretch for a binary partner. Nevertheless, perhaps this new development will lead to taking a fresh look at the possibility that there might be more in our immediate neighborhood than originally thought. It's a beautiful day in the neighborhood…

Oops. I forgot that I read that. He threw me off when he said "Death Star".

"…only 40 light-years from Earth"

Kind of far away to be a binary partner don't you think??? If it was 40AU instead (average orbital radius of Pluto) then sure…

Your a binary partner!!

Do the know if its our Suns binary partner?
