Good day! I am currently a freshman at a master's course in astronomy as preparation for studies overseas (I need a master's degree to be able to apply a master's degree overseas). I am wondering of possible thesis topics acceptable for a master's degree. The school I am currently in has a few telescopes, but no observatory. So an experimental and observational field could be a bit of a problem, so I am thinking of an empirical or theoretical approach to a subject. Anyone have good ideas? The master's degree has a duration of two years, it's better to start early. Thank you in advance.
