(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.
