Título: Characterization of Gaia Transients

Resumo: The currently available large photometric surveys are discovering a vast amount of transients, ranging from supernovae to dwarf nova outbursts. In particular, the Gaia satellite is discovering such phenomena at a rate of about three per day.A complete follow-up of these objects is barely feasible and a preliminary characterisation is crucial to isolate the targets which deserve a detailed study.The Cassegrain Spectrograph is ideally suited for this task, sitting on a 1.6m telescope and providing sufficient resolution to provide a useful spectrum in a reasonable amount of time.The present proposal is aimed at observing Gaia transients for characterisation and trigger a more complete follow-up observations with larger facilities. This is the resubmission of a project which was aleray awarded time in semester 2020A but had to be suspended because of the outbreak of the COVID-19 pandemic.
