Regarding the dark energy debate/question, has anyone factored for the output of the stars themselves?

Disclaimer: I know enough about astronomy to know that I know pretty much nothing.

As dark energy was explained to me, it is a placeholder in the equation(s) for measuring the expansion of the universe. Rephrasing, we know the universe is expanding but we can’t account for some amount of the force involved.

I hope I am making sense and I am not too far out in the weeds.

To my question: all of the stars are blasting out not just photons but also substantial amounts of physical matter in various states (gas, plasma, solid) that also includes material from the various objects in the solar system (eg atoms of water from mars). Wouldn’t that mixture of massless photons and physical material have some significant influence on everything else?

If you know pretty much nothing and thought of this as easily as you did, I’d say it’s certain that scientists who have dedicated their whole lives to answering that question have also had the same idea by now or understand why the idea is flawed.
