Earlier quoted context omitted.

TFA? I'm getting "The Force Awakens". Or "Teach For America".

It seems to be a discussion board internet meme. I am not sure of the actual history, but my impression is that it started as "Did you read the fucking article?" which is sometimes rebutted with "Yes, I read the fucking article." and then "read the fucking article" became RTFA and now some people use TFA to mean The Fucking Article. (Or maybe people more polite than me always used RTFA rather than writing it out. I h…

...and RTFA borrows from the older RTFM (which of course pairs with TFM), and "M" indicating the Manual, or rather Instructions Manual, harkening back to the "man" command in Unix.

I read that as Paris. On the plus side it makes more sense now. Should probably go to sleep...

Last Tango in Pairs We'll Always Have Pairs Pairs exist to remind you dreams are real

Damn you. Until the last line I consistently read Paris. Which was the point of course but I wish I'd have paid more attention after misreading the title :D

Could Jupiter have been a failed pair?

No, Jupiter is a planet not a star. Brown dwarfs start out well over a dozen times more massive than Jupiter. Planets form from a proto-planetary disk, as Jupiter did (you can tell because it is in the same orbital plane as the other planets, the same as the original plane of the disk).

99.9% the mass of the Solar System is in the Sun. 0.1% of the mass of the Solar System is in Jupiter. It's very big for a planet in our Solar System but it is very small compared to even the smallest stars.

> Many stars have companions Most stars. Many years ago, i downloaded a copy of the Gliese star catalogue, and set about generating some star charts of nearby space in VRML (which should give you some idea of just how many years ago that was). Multiple stars are listed as multiple entries in the catalogue, and i realised that if i drew markers for each one, they'd overlap and look terrible. Never mind, i thought, the…

Same!

This is such a common problem for me today, working on small scale city maps. Hearing about it on a universal/galactic scale, and also in the now redheaded stepchild of earlier web tech (i.e. IE) is not only incredibly cool and impressive (today), but also to hear of the possible data inference implications is somewhat exciting.

Could Jupiter have been a failed pair?

It does emit more radiation than it absorbs, which is star-like.

But it does so for completely different reasons - gravitational energy release due to gradual contraction rather than nuclear fusion.
