Switching from physics to astro in the app process is fine I would assume, I don't think anyone would hold that against you. As for the issue of the 15th, I'm thinking and this is just speculation, but I'm thinking that their last hope to find funding for you is if they end up under their projection of acceptances and right now they're probably boarder line. The situation is tricky, since you won't know about your funding there until it’s too late for the other offers. If it was me, and this may be just me, I'd just assume that no funding exists and decide whether I want to go to this other school or reapply next year. That's totally a personal judgment call though; others might have a better suggestion.
I agree. It sounds like the professor is waiting to see how many astronomy prospectives accept. From reading your posts it sound like you are talking about UT Austin. UT Austin has a pretty strong astronomy program so I wouldn't count on it happening, but you never know. It's okay to hold your offers until April 15th if you're unsure. But if you think you would rather try again next year if funding does not come through for this school, then decline your second offer. You only really need the one offer if you are deciding between reapplying or accepting this offer with astronomy funding. But if you honestly see yourself attending the second school, mull it over.
