L-type star

(spectral type of star cooler than an M-type star)

An L-type star (L) is within the L-class, a spectral class indicating stars with reduced titanium oxide lines (which distinguish M-type stars), with metal hydride and alkali metal absorption lines, and a surface temperature in the range of 1300-2000 K. The spectral energy distribution peaks in the mid-infrared/near-infrared range. This encompasses some brown dwarfs and red dwarves (L dwarfs) and potentially some cool giant stars.
