Reply to comment by Chazmer87 in JWST snaps first chemical profile of an exoplanet atmosphere | We knew Wasp 39b was rich in CO2, but now we have the full molecular picture by chrisdh79
Yes why ? It's when the star winds interact with the planet athmospere and create new particuls

If by star winds you mean light

More like the pressure that photons creates as they travel.

Solar wind and presumably "star wind" conventionally refers to charged particles being lost from the corona of the star and traveling through space. This has nothing to do with photochemistry which involves light itself.

I know that. I was referring to the comment about star wind. Yes it's charged particles being released but photonic pressure plays a part also. Wasn't referring the chemistry but the physics.

Yes it would be inaccurate to say this powers photochemistry. As I pointed out.

I guess, it sounds a lot like something photo synthesis would be classified under.

Yeah, it is a hot gas giant planet with a high temperature of 900 °C, it's very unlikely to host any life.

Yes, just wanted to point out why someone might find the term an exciting discovery thinking it implies that when it does not.

The article explain it "concrete evidence of photochemistry – chemical reactions initiated by light hitting a planet's atmosphere." so he might just have read the keywords
