What would happen if an errant icy planet impact an star with similar size?

The errant planet is similar in size with the star and it's made all of water. Usually is icy, but probably gonna melt when approach the star.
What happens during the process of collision between the star and the planet?
I didn't care about the size, just need to be similar. Points extra for different examples and examples with different sizes.
