Deuteration of water in protoplanetary discs during luminosity outbursts: model predictions for FU Ori discs

Anastasiia Topchieva, Tamara Molyarova, Anton Vasyunin

Luminosity outbursts of FU Ori-type objects (FUors) allow us to observe in the gas the molecules that are typically present in the ice in protoplanetary discs. In particular, the f…
