WASP-18b Nymeyer, Maxted
● 4 IRAC eclipses, 2 orbits
● ~3000 K, BB-like
● A~0, low day-night redist.
● Inversion suggested
● Submitted to ApJ

This is the hottest planet today?

WASP-33b should be hotter, depending on albedo.

There are two conflicting results

http://www.nature.com/nature/journal/v447/n7145/abs/nature05863.html
T=2300+/-200 K

http://arxiv.org/abs/0908.1977
T=1440+/-150 K

Yes possible.

ttp://arxiv.org/pdf/1004.4551v1
Assuming a stellar Te= 7430+/-100K, zero albedo and uniform redistribution of incident flux, the equilibrium temperature of the planet is 2710+/-50 K.
