the ultra cool brown dwarf

i been doing some research on the theory that jupiter could be turn into a brown dwarf but as i became more and more disapointed i came across the site www.newscientist.com... who have claimed to have found a ultra cool brown dwarf only 15% bigger than jupiter. So now that mass is out of the question why can't juipiter be turned into a star?

Last time i looked Jupiter had a redish colour so turning it into a brown star is gonna take a lot of paint my friend...

But seriously turning planets into stars is not something you can just do. You are seriously gonna have to get clearance from the Galatic Federation of Light. And last i heard there construction laws are pretty strickt.

You first have to fill in an A45/B request.....

But to be honest i wouldn't know ,sorry

I've been doing some "research" as well and i to was disapointed 'cause it would really help global warming and all to have not one but two suns in our solar system but i think i have the answer!!

given the fact that Jupiter is made up of 90% hydrogen and 10% helium all we need is

www.zippo.com...

oh and somebody to travel the distance and light *snip* and voila....

so any volunteers???

If you could do that what would be the ramifications for the rest of the planets?

Would gravity change, would it's orbit change etc.?

lol...

I would go there in a second and pretty sure many other folks would too.

With the hangover I got I am up for the mission. A dumb question on my part but do we need oxygen to make this happen?

Damnit...now i'm even more disapointed. I knew we forgot something. So to answer your question -aginstitall-

"So now that mass is out of the question why can't juipiter be turned into a star? "

I'm sorry but we are unable to help you set Jupiter on fire...damn we were this close....

what exactly is the difference beetween a planet / star ?

is a star not just a gas giant type planet that has somehow managed to start and create fusion within itself?

and what starts a star's fusion .. actualy, how are stars made?!

I could do a lot of copying and pasting but i'll just post the link. Makes for better reading with a the pictures still in place.

But in short...just apply some pressure

It's not possible for a planet to become a star. Jupiter is about 1/80th the mass it would need to become a star.

This page may help.

ETA: You don't just have to "apply some pressure" you need a critical mass before it could become a star, and Jupiter isn't even close. It has the wrong type of hydrogen, not enough lithium for a fission device, and hydrogen explosions aren't the kind of reaction that will continue once it starts. Eventually it will burn itself out, and pretty quickly at that.

It begins with some guy being disapointed when he found out that he couldn't turn Jupiter into a star. How would you think i was going to apply pressure to the biggest planet in our solar system?...a really big paper-press?

Gee, who was the one that said "just apply some pressure" here? Sure as hell doesn't look like it was me now does it. But you're right, I was just stupid to bother trying to inject real science to a thread where the second reply had a link to Zippo in it. Terribly sorry for that.

Gee, doesn't critcal mass equal "applying some presure" but on a bigger scale??

sorry for insulting your intelligence......

I love astronomy, use to be one of my favourite subjects.

Yes it is possible for jupiter to transform into a star but it would have to be many times larger. In the old text books of mine there was an assumption that jupiter was a failed star and that Neptune and Uranus were considered very weak dwarf blue stars... although this was obviously proved incorrect as these planets were formed straight from the development of the solar system, they were in no way former companions of the sun.

Like I said, very interesting....

This is partly why the "planet X" theory has been all but thrown in the garbage, the smallest brown dwarf would have to be many times larger than jupiter and three times brighter or so, so considering jupiter is among the brightest objects in our skies (4th) any dwarf in our area of space would have to be among the brightest and would have been spotted even if covered by an astroid field (jupiter is behind an astroid field from us so that should be evidence enough).

From my extremely basic understanding of gravity and mass, as long as the planet's mass stayed the same, it's gravity wouldn't change.
So, Jupiter could be replaced by a relatively massed brown dwarf and there wouldn't be much of a affect, aside from loosing a striking figure in our night sky.
As for it turning into a brown dwarf... doesn't seem bloody likely.

just came accros this little tid bit:

Consideration is given to the possibility of turning Jupiter into an artificial star by seeding it with a primordial black hole so that Eddington limited accretion onto the hole would produce energy sufficient to create effective temperatures on Europa and Ganymede that would be similar to the values on earth and Mars, respectively. It is suggested that the feasibility of this scenario depends on the prevalence of primordial black holes and the efficiency of conversion of rest mass to energy for black hole accretion from a dense medium. A scenario for the 'stellification' of Jupiter is proposed. (adsabs.harvard.edu...).

There is a hugh fear that the hadron collider could create a black hole. even tho the collider is massive if it could be condenced and re created on jupiter i would love to see the affects. but when it comes to turning jupiter into star every one thinks big mass big density, maybe the solution is we need to think smaller.

Mass is still a factor. Brown dwarfs are considered to be at the demarcation line between a (massive) planet and a star. The newly discovered Y-class brown dwarf [CFBDS0059] is still 15-30% more massive than Jupiter, hence, the Jovian Giant is still too small.

It is hotter on the surface of Venus than it is on this sun! Looks like they've found ammonia there too.

Nice find.

ya you never read the artical about adding the primordial black to increase the density of the area to start a fusion reaction

Jupiter is a planet, a massive planet indeed, but it is just a planet none the less,
Despite the similarities between itself and a 'brown dwarf' star,

However if technology became advanced enough, and you added the right amounts of the right heavy elements, waited a few thousand years (unless you could speed this up with technology) for Jupiter to adapt,

Then by all means, feel free to use whatever ignition method your people will have thought of by then to start Jupiter burning

No, I have not. I only have access to the abstract you posted. Perhaps you could provide a synopsis of the paper (especially its conclusion wrt "the possibility of turning Jupiter into an artificial star by seeding it with a primordial black hole...") and the feasibility of such? Thanks.



I do notice that this paper was published almost 30 years ago and has since only been cited twice. Take from that what you will. Although, the idea of seeding Jupiter with primordial black holes in order to terraform some of its moons is way cool, I doubt it is feasible to do so. Of course I'm no theoretical astrophysicist. So, if you'd care to enlighten me I'm all ears.
