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 disks. In particular, the fraction of deuterated water, which is usually mostly frozen in the midplane of a protoplanetary disk, has been measured for the first time in the gas of the disk around FUor V883 Ori. We test the hypothesis that the observed high HDO/H2O ratio in the V883 Ori protoplanetary disk can be explained by luminosity outbursts of different amplitude, including a series of two consecutive outbursts. Using the ANDES astrochemical code, we modeled the distributions of water and deuterated water abundances under the action of luminosity outbursts of different amplitudes (from 400 to 10,000 L⊙) and at different stellar luminosities at the pre-outburst stage. We show that the best agreement with the observed HDO/H2O profile is obtained for outburst amplitudes of 2000 and 10,000 L⊙, while the observed bolometric luminosity of V883 Ori does not exceed 400 L⊙. We discuss possible reasons for this discrepancy, including the presence of past luminosity outbursts, the age of the star, and the influence of additional heating mechanisms in the midplane of the protoplanetary disk. We also consider how the high observed HDO/H2O ratio may be related to the evolution of the chemical composition of the ice in the protoplanetary disk and the chemical processes activated under outburst conditions.
