“…In the coming years, several facilities will or may become available for observing HD rotational lines. The HIRMES instrument for SOFIA is currently undergoing commissioning and is due to be delivered at the end of 2020 (Richards et al 2018). HIRMES will have a high spectral resolution of R ∼ 100000, allowing us, for the first time to spectrally resolve the HD 1 -0 line.…”

Context. Hydrogen deuteride (HD) rotational line emission can provide reliable protoplanetary disk gas mass measurements, but it is difficult to observe and detections have been limited to three T-Tauri disks. No new data have been available since the Herschel Space Observatory mission ended in 2013. Aims. We set out to obtain new disk gas mass constraints by analysing upper limits on HD 1 -0 emission in Herschel /PACS archival data from the DIGIT key programme. Methods. With a focus on the Herbig Ae/Be disks, whose stars are more luminous than T Tauris, we determine upper limits for HD in data previosly analysed for its line detections. Their significance is studied with a grid of models run with the DALI physical-chemical code, customised to include deuterium chemistry. Results. Nearly all the disks are constrained to Mgas ≤ 0.1 M , ruling out global gravitational instability. A strong constraint is obtained for the HD 163296 disk mass, Mgas ≤ 0.067 M , implying ∆ g/d ≤ 100. This HD-based mass limit is towards the low end of CO-based mass estimates for the disk, highlighting the large uncertainty in using only CO and suggesting that gas-phase CO depletion in HD 163296 is at most a factor of a few. The Mgas limits for HD 163296 and HD 100546, both bright disks with massive candidate protoplanetary systems, suggest disk-to-planet mass conversion efficiencies of Mp/(Mgas + Mp) ≈ 10 to 40 % for present-day values. Near-future observations with SOFIA/HIRMES will be able to detect HD in the brightest Herbig Ae/Be disks within 150 pc with ≈ 10 h integration time.Article number, page 1 of 13 A&A proofs: manuscript no. gasmass in Sections 2 and 3, respectively. In Section 4, we explore the disk mass constraints, with a focus on HD 163296, and discuss the potential for gravitational instability. In Section 5, we compare the mass of disks, stars, and planetary systems for stars over 1.4 M . We also discuss future observations of HD with SOFIA/HIRMES (Richards et al. 2018) and SPICA/SAFARI (Nakagawa et al. 2014;Audley et al. 2018).

“…The filter wheels design is based on the filter wheels that were designed and built for the Rapid infrared IMAger Spectrometer (RIMAS) instrument 5 and the HIgh-Resolution Mid-infrarEd Spectrometer (HIRMES). 6 Each wheel has four positions to accommodate the broadband and narrow-band filters. One position is open on each wheel, while one position on the upper wheel is blocked for dark current measurements, as needed for the camera operation and measurement of the level of scattered light in the camera itself.…”

The PRime-focus Infrared Microlensing Experiment (PRIME) camera is part of the joint NASA-JAXA project in support of the spaceflight Roman Space Telescope project development. It is designed to accommodate the needs of the large-scale survey of the microlensing events in the Galactic bulge. The camera is placed in the prime focus of the 1.8-m telescope dedicated to this project. With four large-format infrared detectors, the instrument covers a field of view about 1.3 square degrees. Over the few years preceding and during the operations of the Roman Space Telescope, the instrument will be used for continuous monitoring of selected fields in the Galactic bulge for microlensing events and a number of other science programs of the consortium.
