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.

• Extrasolar Planets Encyclopaedia

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.
