I'm used to reading excellent articles by Emily, but this one I found to be of truly extraordinary interest:

The latest Sky and Telescope has a nice article on this - I was astonished that they gave even odds to finding a brown dwarf CLOSER than Alpha Centauri.

I was astonished that they gave even odds to finding a brown dwarf CLOSER than Alpha Centauri. Given that smaller stars are more numerous than larger ones, I'd have thought it almost a certainty they'd find a number of brown dwarves closer than Alpha Centuri. What I'm wondering is whether a brown dwarf inside the Oort Cloud might be responsible for otherwise-difficult-to-explain things like the orbit of Sedna. --Greg |
