Exoplanets
- Exoplanets.org - Compilation of orbital and transit parameters for exoplanets containing only the most robust orbital parameters well-constrained by radial velocity and transit measurements as collected from the peer-reviewed literature. It includes a plotting tool for creating full-color, presentation- or publication-quality plots.
Stars and White Dwarfs
- IRTF Spectral Library - Near-infrared spectra of late-type stars, brown dwarfs, and our giant planets. Maintained by John Rayner.
- White Dwarf Catalog - Catalog of Spectroscopically Identified White Dwarfs.
- SLoWPoKES - Sloan Low-mass Wide Pairs of Kinematically Equivalent Systems. Binary systems with one low-mass (mid-K to M spectral types) component.
- Washington Double Star Catalog - Database of astrometric double and multiple star information. Maintained by the United States Naval Observatory.
Multiple Systems
- Washington Double Star Catalog - Database of astrometric double and multiple star information. Maintained by the United States Naval Observatory.
- SLoWPoKES - Sloan Low-mass Wide Pairs of Kinematically Equivalent Systems. Binary systems with one low-mass (mid-K to M spectral types) component.
- Very Low-Mass Binaries - Stellar (and sub-stellar) binary systems with total estimated mass <0.2 M_solar known in the literature.
Brown Dwarfs
- BDSS Archive - Near-infrared spectra of M, L, and T dwarfs obtained with Keck-NIRSPEC. Maintained by Ian Mclean.
- Spex Prism Spectral Library - Low-resolution, near-infrared spectra of M, L, and T dwarfs obtained with IRTF-SpeX. Maintained by Adam Burgasser.
- Dwarf Archives - Compilation of known L and T dwarfs. Maintained by Chris Gelino.
- Very Low-Mass Binaries - Stellar (and sub-stellar) binary systems with total estimated mass <0.2 M_solar known in the literature.
Stellar Clusters
- Stellar Clusters in the Galaxy and the Magellanic Clouds - Published data for stars in open clusters.
