Brown dwarfs are the coolest class of stellar objects known to date. Our present perception is that brown dwarfs follow the principles of star formation, and that brown dwarfs share many characteristics with planets.

The Classification of L Dwarfs
2001To highlight the need for new spectral types, a brief review of the discovery of very low luminosity dwarfs — cooler than type M9.5 — is presented. The reasoning behind the choice of letters “L” and “T” is also given. Our philosophy of spectral classification is explained and we use this philosophy to construct an L dwarf typing scheme.

ASTRONOMY Dwarfs are low mass, very cool, main-sequence stars, and recent large-scale star surveys have identified a new spectral class, called the L-dwarfs. The low estimated masses of L-dwarfs suggest that most of these objects are brown dwarfs that are rich in hydrides rather than methane. McLean et al. have obtained high-resolution spectra of six L-
