Abstract

Context: The Mid-InfraRed Instrument (MIRI) will fly on the James Webb Space Telescope (JWST) nominally in late 2018. MIRI contains a spectrograph of spectral resolution ∼3000 in the band 5-28 µm. One of the uses of MIRI will be the study of protoplanetary disks (PPDs). Aims: Assess the detectability of organic molecular features in various simulated PPDs and the typical exposure times needed. Determine if different types of disks produce different organic spectra. These results will help plan the MIRI guaranteed observing time. Methods: I have compiled a library of mid-infrared emission spectra using the ProDiMo (PROtoplanetary DIsc MOdel) software package. I used a fast line radiative transfer code FLiTs to compute spectra based on the ProDiMo output. A mid-infrared spectrum of FT Tau made by the Spitzer space telescope was used for analysis of the resulting spectra. Afterwards I apply sensitivity estimates for the JWST/MIRI MRS with the resulting spectra to determine the minimum exposure time required to guarantee the detection of various spectral lines of interest.
