Ultracool Dwarf Catalog

This catalog includes most of the dwarfs you can find in Davy Kirkpatrick's Archive of L Dwarfs and Adam Burgasser's T dwarfs page, although the information here is more complete because litterature has been revised to include more physical characteristics. The SDSS group of Suzanne L. Hawley provided the photometry of more than 600 of the dwarfs in this catalog (thanks to the help of Kevin Covey). You can find also spectra from Leonardo Testi and from Eduardo L. Martin.

For every dwarf you can find:

• an arbitrary running number called UDC
• the name
• the coordinates
• the photometry in the V, R, I, J, H, K, L and M bands if available
• the projected axial rotational velocity in km/s if available
• the heliocentric radial velocity in km/s if available
• the parallax in arcseconds (or in parsecs) if available
• the spectral type
• the equivalent width of Hα emission in Å if available
• a link to a file with the spectrum of the dwarf in ascii or fits format if available
• the wavelength interval of the spectrum (if exists) in microns
