Astronomers find a bunch of loser stars that could barely cook a pizza

Astronomers have discovered 14 failed stars, or brown dwarfs, that are only 350 to 620 degrees Fahrenheit. Compare this with the 10,000-degree blazing awesomeness of our sun.
For the intriguing article about these wimpy stellar objects:

And for more local brown dwarf news, here's a relevant video:
A new NASA mission may discover dim stars very close to our Sun. Super-cooled detectors in the Wide-field Infrared Survey Explorer will seek hidden treasures across the entire sky, taking at least 1.5 million images - each 4 megapixels in size

I wonder if there are even "bigger" or smaller loser "stars" out there too. Think about it.

What about the "stars" that never shine because of their size? How small do they have to be to not start the fusion process? They say jupiter doesn't have enough mass to begin the fusion process so could there be trillions and trillions of stars that never started to shine? Now I don't mean gas giant planets orbiting stars, I mean "stars" that never begin to shine. If there are a lot of them, what does that mean in terms of dark matter? Could these unlit "stars" be the dark matter? Or better yet, the "missing" matter?

That makes a lot of sense that a great number of these brown dwarfs take up the vast percentage of what could be considered dark matter.

Hi Krumple!

It is also possible that these "losers" are easily absorbed by larger stars.
