N_exoplanets > N_T_dwarfs?!
I just realised something that seemed a bit odd today.
Pre-Kepler, we had ~450 exoplanets. That’s arguably ~750 now. And the big thousand can’t be far off.
However, T-dwarfs and exoplanets* were first confirmed at more or less the same time (1995-1996). But, there are still less than 200 T-dwarfs known, and if we add in the L dwarfs then we still don’t reach the magic thousand.
It just seems odd that the planetary regime is better-sampled than the bottom end of the ‘stellar’…
*Ignoring the pulsar planets, of course, because they live in the box marked ‘weird’ and ‘WTF?’. If we count them, then the exoplanets date is 1991.
