The Coldest Brown Dwarf (Or Free Floating Planet)?: The Y Dwarf WISE 1828+2650

http://arxiv.org/abs/1301.1669

Its both you noobs!

When a star evolves it passes though a brown dwarf stage, then can be free floating if it doesn't have a host star to orbit (as it continuously evolves becoming a rocky world in its center, forming the new life hosting "planet" in its interior).


Its easy! Big, hot and bright (what they call stars).... smaller, gaseous, not so bright (what they call brown dwarfs)... smaller, rocky (differentiated) not shining any longer (what they call planet), dead cold world that smashes into other bigger bodies making shrapnel (asteroids/meteorites)...



See? Its not hard to conceptualize!

Helpful comments will be appreciated, but if the user does not want to address the issues being presented they will be ignored. This is a blog dedicated to trying to explain how to make sense of the discovery that planet formation is star evolution itself, not a blog for false mainstream beliefs.
