About

Professor Seppo Mattila is a faculty member in the Department of Astronomy at the University of Turku, Finland. His research encompasses various aspects of supernovae, including the discovery of young, oxygen-rich remnants and the observational diversity of Type II supernovae. He has contributed significantly to the understanding of transient events through works such as the spectropolarimetry of nuclear transients and studies on bipolar explosions in Type IIP supernovae.
