Four-of-a-kind? Comprehensive atmospheric characterisation of the HR~8799 planets with VLTI/GRAVITY

We explored the atmospheres of the HR 8799 system of directly imaged planets using petitRADTRANS atmospheric retrievals. This required reprocessing existing data, preparing new observations from VLTI/GRAVITY and combining additional archival spectroscopic and photometric datasets. We ran 95 retrievals across the four planets, and include here the full set of outputs from the sampling process, as well as synthesised results for each retrieval. Finally, we also include templates for running these retrievals.

This data, together with the results of the retrievals and templates for running similar emission spectra retrievals are included in this Zenodo archive. Additional README files are included throughout the archive in order to explain file structures, units, and to provide original references where necessary. An archived repository of the petitRADTRANS code can be found at https://doi.org/10.5281/zenodo.10892021, while the up-to-date repository is available at https://gitlab.com/mauricemolli/petitRADTRANS.
