TL;DR: In this paper, the spectral energy distribution of the HR 8799 planets is modeled as a mixture of clouds of varying opacity, similar to the patchy cloud structures on Jupiter and L/T transition brown dwarfs.

TL;DR: The comparison of the performances offered by a Natural Guide Star (NGS) system upgraded with the state-of-the-art technology and those delivered by existing Laser Guides Star (LGS) systems suggests rethinking the current role ascribed to NGS and LGS in the next generation of AO systems.
