SPACE.com story
Spitzer? We don't need no steenking Spitzer!
Quote :
The team took more than 600 images of OGLE-TR056b with both telescopes. The planet is hotter than any detected by Spitzer so far — its atmosphere is more than 4,400 degrees Fahrenheit (2,400 degrees Celsius).

The observations also indicated that the planet has little to no cloud cover and a static atmosphere with little circulation, López-Morales told SPACE.com in an email.
I guess that means there's little heat being circulated to the dark side, rather like ups And b, which for such a hot planet would be expected from the pM/pL division.

This is awesome! Given that the OGLE planets are typically so far away, I wouldn't have expected to ever hear their names in a direct detection. UniverseToday has another article on it.

Here's the paper for OGLE-TR-56b. (Claims to be "forthcoming", but is available there).
http://www.aanda.org/index.php?option=article&access=doi&doi=10.1051/0004-6361:200811268

TrES-3 b was also detected. Here's the paper. (Forthcoming as of now)
http://www.aanda.org/index.php?option=article&access=doi&doi=10.1051/0004-6361:200811239

This is also great news. I <3 Spitzer, but as the paper says, we're going to lose a lot of its capabilities when its cryogen runs out. Ground-based detection of exoplanets in the infrared will help fill in the gap between Spitzer and JWST.

Edit:
TrES-3 b paper on ArXiv: http://arxiv.org/abs/0901.1878

What is the "current models of the physical properties of this
planet's upper atmosphere"?
