Stalker's work

What are the temp ranges and compositons depicted?

I'm creating a new John Whatmough's like website and I need representations of gas giants in all sudarsky's classes. I created a new class, Z for Zero, cooler than class I with clear atmosphere dominated by methane clouds. This is for the last, blue planet.

There is a problem, some planets dont fit in the sudarsky classification, but between two classes or in two classes at the same time. For this ones i created intermediate classes, just for the visual effet.

In order in the image:

Class V: Silica clouds
Intermediate class IV-V
Class IV: Sodium haze
Intermediate class III-IV
Class III: Rayleigh scattering
Intermediate class II-III
Class II: ice and water clouds
Intermediate class I-II
Class I: Ammonia cloud (Jupiter/Saturn analog)
Intermediate classe Z-I
Additionnal class Z: methane cloud

I don't ask this to sound like I'm being contentious; are these scientifically plausible renderings. (I like how they look, so I hope the answer is yes.)

It's based off the work of Sudarsky et al who calculated the spectra and appearances of planets based on what chemicals can condense at various temperatures in a Jovian atmosphere.

It's definitely plausible, but it's outdated. The exoplanet zoo is looking more complicated than the Sudarsky scheme.

Sorry for not understanding your question. Sirius_alpha made a good answer. For me the Sudarsky classification is more a "visual range of temperatures" than a real rendering of extrasolar planets. And I think it work a little only on gaz giants.

A directly imaged planet with M spectral type.

That looks spectacular!!!!

Thanks you, I was working on something like for a very long time, it's'the first time it really speak of both planetary and stallar properties of that kind of object.
