I'm working on a project and I need a list of at least 50 stars with their known sizes (they must be below 50 solar diameters), but all star search engines I found didn't offer star sizes in the results, or didn't provide me with ways to search by size.
Does anyone know where I can find this information? Thanks in advance!
Also, while we're on topic, what's the estimated size of Betelgeuse? I'm finding values ranging from 500 to 700 solar diameters, which is a big difference I can't really ignore.
