The Hypatia Catalog Database: A Web-Based Interface for Exploring Stellar Abundances

TL;DR

The Hypatia Catalog Database provides an extensive, web-based platform for exploring high-resolution stellar abundances and properties of stars near the Sun, supporting research in stellar and planetary science.

Contribution

This work introduces a comprehensive, interactive database with 72 elements for nearly 6,000 stars, integrating literature data and offering tools for easy exploration and analysis.

Findings

Largest database of stellar abundances within 150 pc of the Sun

Includes data for 72 elements across 5,986 stars

Provides downloadable data and visualizations for research use

Abstract

The Hypatia Catalog Database (www.hypatiacatalog.com) is the largest database of high resolution stellar abundances for stars within the solar neighborhood. It currently offers 72 elements and species within 5,986 stars, 347 of which host planets. The Hypatia Catalog Database features an interactive table and multiple plotting interfaces that allow easy access and exploration of stellar abundance data and properties within the Hypatia Catalog (Hinkel et al. 2014, 2016, 2017). The Hypatia Catalog is a multidimensional, amalgamate dataset comprised of stellar abundance measurements for FGKM-type stars within 150 pc of the Sun from carefully culled literature sources, currently totaling 161 datasets, that measured both [Fe/H] and at least one other element. In addition to abundances, stellar properties and planetary properties, where applicable, have been made available within the online Hypatia Catalog Database. Data and plots can also be downloaded through the website for use in personal code or presentations, respectively. 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.
