No unfortunately (or not that I've noticed), though you drop out of stealth if you open fire or use your afterburners. It would be cool if you came out of stealth at half power; that would make it pretty costly, since power and power regen are the stats that dictate how long you can sustain your weapons in a firefight (missiles not withstanding).

That's very cool re: The Expanse. Alastair Reynolds, an astronomer turned sci-fi author, explores "weaponized astronomy" a lot in his books, especially the opening chapters of "Inhibitor Phase". Without too many spoilers, there's a ship that cools it's hull close to absolute zero and uses cryogenic gasses for thrust in order to maneuver, so that it isn't radiating IR. And they have to time their operations so that they aren't seen occluding the sun.
