Even with over 6000 known SNe, we have only direct information about the progenitor star for a handful of explosions. Here, I summarise the observational constraints of the massive progenitor stars of several core-collapse supernovae.ELETTRONICOenConference paper10.1017/S17439213160049202-s2.0-84992642855https://www.cambridge.org/core/journals/proceedings-of-the-international-astronomical-union/article/observational-constraints-on-the-progenitor-of-corecollapse-supernovae/5DAB7E626BD25B4947196B2BFE52EA212016IAUFM..29B.209EFIS/05 - ASTRONOMIA E ASTROFISICA
