A Class L star is a type of brown dwarf. They are 65 - 80 times as massive as Jupiter and their temperature is generally in between 1,880 to 3,860°F (1,026.7 to 2,126.7°C) [1]. More massive Class L stars are at the limits of smallest stars capable of fusing hydrogen, whereas less massive ones fuse deuterium and lithium instead[2]. They appear to be a dim orange-red with their spectrum peaking in the infrared.
Class L stars often begin their life with emissions in the Class M spectrum with a temperature of over 4,940 F (2,726.7 C) but cool off and become dimmer over time.
Class L stars have a habitable zone in between 0.007 and 0.04 AU, or between 1,050,000 to 6,700,000 km, which is 10 - 54 times as close as Mercury's orbit to the Sun. This close distance would leave the planet tidally locked to the star. This combined with the low temperatures, leaves Class L stars extremely poor candidates for life.
