Seminarium IOA - dr Cyrielle Opitom

Streszczenie: Comets are pristine relics of the protoplanetary disk, where the planets formed and evolved, and preserve in their ices important clues about the early solar nebula. When a comet approaches the Sun, the ices it contains sublimate to form a huge atmosphere of gas and dust called the coma. Spectroscopy of cometary coma provides invaluable cues about solar system formation. However, comets are notoriously difficult to observe. They are extended objects, whose emission lines can be difficult to detect using ground-based instrumentation. In this seminar, I will explore how new and upcoming UV/optical spectrographs and IFUs are essential to study the composition of comets, understand their activity, and investigate the origin of species in their coma.
