"content": "Italian astrophysicist Margherita Hack was born #OTD in 1922.\n\nShe graduated with a degree in physics with a thesis on Cepheid variables, based on her studies in the Arcetri Observatory. Her research primarily focused on the classification \u0026 evolution of stars, particularly through the use of spectral analysis. She published numerous scientific papers \u0026 contributed to the understanding of stellar atmospheres and the chemical composition of stars.\n\nhttps://en.wikipedia.org/wiki/Margherita_Hack\n\n#science #astrophysics\nhttps://files.mastodon.social/media_attachments/files/112/604/423/701/741/113/original/0757414707280d31.jpg\n",
