WASP-19b does not fit current classification schemes

Post by Lazarus on 28th June 2013, 1:53 pm

Physical properties, transmission and emission spectra of the WASP-19 planetary system from multi-colour photometry

The planet is more bloated and the system is older than previously thought. Also the atmosphere seems to be a bit of a puzzler:
We conclude that: there is no evidence for strong optical absorbers at low pressure, supporting the common idea that the planet's atmosphere lacks a dayside inversion; the temperature of the planet is not homogenized, because the high warming of its dayside causes the planet to be more efficient in re-radiating than redistributing energy to the night side; the planet seems to be outside of any current classification scheme.
