Dr. Travis Metcalfe | Constraints on the Magnetic Morphology of Old Sun-like Stars

Speaker(s): Dr Travis Metcalfe (White Dwarf Research Corp) Date: 16 September 2022 – 14:30 to 15:15 Venue: INI Seminar Room 1 Session Title: Constraints on the Magnetic Morphology of Old Sun-like Stars (Contributed speaker) Event: [DY2W01] Dynamos in planets and stars - similarities and differences Spectropolarimetry can provide observational constraints on the strength and morphology of the large-scale magnetic field in Sun-like stars. To date, very few measurements have been available for stars that are more evolved than the Sun. Recent evidence suggests a substantial transformation of the large-scale field in older stars, so new measurements are finally becoming available. I will present the latest spectropolarimetric observations from the Large Binocular Telescope, and offer an interpretation that yields a new understanding of the evolution of Sun-like stars across this magnetic transition.
