More info here. All of it contradictory :)

So I'm still wondering if it is proper to think of a star's gravitational field being caused not just by its matter, but also by all the photons it has pumped out over its lifetime.
- avar 16y agoIt doesn't make any sense to define a gravity field by photons. They're massless, so they don't attract anything, and most of the photons a star has produced over its lifetime are speeding away across the universe billions of light years away from it. Only things with mass can attract other objects with the gravitational force. Photons aren't in that category.
