= Fast blue optical transient
{wiki=Fast_blue_optical_transient}
Fast Blue Optical Transients (FBOTs) are a type of astronomical phenomenon characterized by a rapid rise and decline in brightness, typically occurring in the optical wavelengths. These events are often linked to cataclysmic occurrences such as supernovae, neutron star mergers, or the collapse of massive stars. FBOTs are distinguished by their exceptionally fast light curves, which reach their peak brightness within just a few days and then fade away quickly, often within weeks.
