I could calculate the Roche Limit for Vega if I knew its density and the density of protoplanets in the circumstellar disk. I'm sure the density of Vega is less than the sun's density of 1.41, and I suspect the density of condensed material close to the star must be similar to iron or rocky...

Howdy, first post, good to be here. I'm sure it will be a learning experience. My question concerns planetary formation and planet orbits for other stars, specifically the star Vega. I'm having a "disagreement" with someone who claims that Vega's mass, diameter, and density prevents the...
