I'll explain this a bit. What types of destruction magic is there? Fire, frost and shock. What does magic need to work? Magika. If the Aetherius is the realm of magic and the origin of magika, wouldn't it also mean there is a nearly limitless supply of it there? So that said if the sun was a hole to the Aetherius it would be a open tap to limitless amounts of magika. Magika that can fuel the use of Fire. Vampires are weak to fire. Not just that, but I believe that It's no ordinary fire either. Since the fire is related to Auri-El/Akatosh it would be divine fire. Vampires originate from Molag Bal, a Daedric Prince being the polar oposite of an Aedra it would make sense to be harmed by divine magic. Conclusion: The sun is just more powerful magic that is imbued with Aedric power which could damage vampires who are in it's presence. It isn't the Aetherius that harms them but the use of it's magika that harms vampires. The Aetherius itself doen't harm them which would explain why they can enter the Aetherius. I hope this helped out a bit, and I also hope it was clear enough to be understood :).
