Emission line in spectrum of a sun

[Kawakaze]

Hi guys, this is a homework question, but i didnt think it belonged with the physics questions. I have the spectrum of a star, it has hydrogen gamma and hydrogen beta absorption lines, but a very very strong hydrogen alpha emission line. What is the significance of this, I would expect a hydrogen alpha absorption line. I figured this to be a B class young hot star.

Thanks!

I think you need to place this in one of the homework sections even if it isn't your average physics question. Hopefully someone will be able to help you there!
