On the nature of fast blue optical transients
Web20 de abr. de 2024 · Using a newly developed model, astrophysicists present a new theory to explain fast blue optical transients, a new class of transients that has boggled researchers since their discovery in 2024. WebTheir fast time to maximum brightness of less than a week, decline over several months, and atypical optical spectra and evolution are difficult to explain within the context of the core collapse of massive stars, which are powered by radioactive decay of 56 Ni and evolve more slowly 2,3.

WebA population of particular recent interest is “fast-evolving luminous transients” (Rest et al. 2024) or “fast blue optical transients” (Margutti et al. 2024). A consistent definition of this “class” does not yet exist; these terms typically refer to transients with rise times and peak luminosities too fast and too Web6 de jan. de 2024 · Abstract The nature of the newly discovered fast blue optical transients (FBOTs) is still puzzling astronomers.
