Optical explosive transients—such as supernovae and kilonovae—are extremely important for understanding the evolution of the Universe, stellar life cycles, and the chemical enrichment of astronomical systems. Many of these transients evolve on very short timescales, and their early phases carry essential information about the underlying physical mechanisms. In this seminar, we present the S-PLUS Transient Extension Program (STEP), which takes advantage of the Southern Photometric Local Universe Survey (S-PLUS) main routine to search for and follow up transients. Moreover, we introduce a novel, in-development technique to infer physical parameters from supernova light curves using a Physics-Informed Neural Network framework, which is being prepared for integration to the Fink broker.
