The SAO/NASA Astrophysics Data System (https://ui.adsabs.harvard.edu) is a digital library for researchers on astronomy and physics, operated for NASA by the Smithsonian Astrophysical Observatory. ADS indexes specific communities on Zenodo related to astronomy, astrophysics and physics which are curated by trusted third-parties.
Please reach out to ADS (adshelp@cfa.harvard.edu) to get your community indexed. Please note that ADS can only harvest your community, if they are able to establish you as a trusted source (e.g. you hold a position in an astronomy/physics department at a university).
