I think this means that their are many adsorptions occurring at the lower wavelengths. But why could this be? What does this say about the star? What I was thinking is that it could imply that the star is surrounded by a large amount of hydrogen gas (a hydrogen gas cloud) but that doesn't seem to sound right.

Any help?


why doesn't your intuition sound right? Stars get their energy from fusing hydrogen together , and our star (sun) has a hydrogen cloud surrounding it...enter image description here

For absorption lines the light Ray's have to pass through "something"

I think my answer is pretty close. :)
