Three Preludes on a Theme of Magnetars: Early Spindown, Nucleosynthesis, and Giant Flares

Explore an astrophysics seminar that delves into three new research areas concerning magnetars - neutron stars with extremely powerful magnetic fields exceeding 10^14 G. Learn how these fascinating objects, which make up approximately 10-50% of young neutron stars in our galaxy, exhibit remarkably slow rotation, produce spectacular flares, and may be connected to fast radio bursts (FRBs). The presentation by Todd Thompson from Ohio State University covers three key topics: the early magnetar magneto-centrifugal spindown process during the proto-neutron star phase shortly after massive star collapse, the potential for heavy element nucleosynthesis during this phase, and new models explaining how neutron-rich baryonic material is ejected during giant flares thousands of years after magnetar formation. The talk also explores how rare, rapidly-rotating magnetars might power super-luminous supernovae and gamma-ray bursts.
