Feature Guest: Stanimir Metchev

Brown dwarfs: giant planets or failed stars? The debate rages on with comparable intensity to the surprisingly violent storms seen to roil these fascinating bodies. To help settle the debate, and for cutting edge discoveries of brown dwarfs and their startling behaviour, Stanimir Metchev joins Justin Trottier at The Star Spot.

If a brown dwarf is neither a planet exactly nor a star exactly, what is it exactly? What keeps it from collapsing? And since they aren’t necessarily brown, what’s in the name? Metchev and Trottier then discuss the weird and surprising behaviour of brown dwarfs, the ubiquity of their massive storms and their role in helping us study the clouds of extrasolar planets,
