Let's say I'm floating in space in a spaceship, and there are some stars around. Now I turn on powerful spaceship engines. This causes a huge acceleration, which causes the brightness of some stars to increase a lot. (Those stars that are up in the pseudo gravity well become bright) Does tidal force from a star increase as much as its brightness? If the star is able to shine brightly, it contains a lot of energy, so it exerts a large gravitational force on those observers that say that it's a bright star, right?
