¿What is a supermassive star?¿How many are there in our galaxy?¿can Do they trace the stellar formation process? Conversation with Eleonora Zari who is working on her Ph.D. in Leiden University trying to use the upcoming Gaia data to solve the problem of supermassive star associations in the Orion constellation to understand the history of star formation in the Milky Way galaxy.
