We aim at investigating correlations between the host star's mass and the presence of wide - orbit giant planets, and at providing new observational constraints on planetary formation models. (arxiv.org)
This can't be explained by simple observational constraints, the team say. (newscientist.com)
But irrespective of all these details, the key point, I think, is that bottom - up, first principles modeling coupled with observational constraints other than the observed GMT evolution still leave room to generate a substantial spread in aerosol forcing and climate sensitivity. (gfdl.noaa.gov)
