The Hypatia Catalog is a multidimensional, amalgamate dataset comprised of stellar elemental abundance measurements for FGKM-type stars within 500 pc of the Sun and all exoplanet host stars regardless of distance. All stellar abundances have been carefully selected from literature sources that measured [Fe/H] and at least one other element. The Hypatia Catalog Database features an interactive table and multiple plotting interfaces that allow easy access and exploration of data within the Hypatia Catalog. In addition, stellar properties and planetary properties, where applicable, have been made available. Data can be downloaded either through the website or through the terminal via our API for use in external plotting routines and data analysis.

A detailed description of the Hypatia Catalog can be found in Hinkel et al. (2014). The Hypatia Catalog and Hypatia Catalog Database will continue to be routinely updated in order to incorporate the most recent stellar abundance data published within the literature.

Help and documentation for the Hypatia Catalog Database can be found in the Help link in the top right corner. Thank yous and acknowledgments to be included in published papers can be found here.
