Hi, I'm Seán, an astronomer at the Oskar Klein Centre, Stockholm University, Sweden. My research focuses on mass loss from massive stars and interacting transients.
Currently, I'm investigating pre-supernova progenitor activity to gain deeper insights into what happens in the final weeks to months of a massive star's life, leading up to core collapse.
