Absolute magnitudes of brown dwarfs, bolometric and in the J-band?
Brown dwarf, J-band (near IR) absolute magnitude versus spectral type.
ℳᴊ = 0.00022084027 S⁴
− 0.0659609823 S³
+ 7.34624126 S²
− 361.274547 S
S = 65 for spectral class M5
S = 70 for spectral class L0
S = 80 for spectral class T0
S = 90 for spectral class Y0
Domain Restricted: S = 65 to 92.
Estimated bolometric correction for brown dwarf J band absolute magnitudes.
BCᴊ = −0.00032222 T + 2.9212
where T is the effective temperature.
L0 brown dwarf has bolometric absolute magnitude of +9.54 (this probably should be one magnitude dimmer)
Y2 brown dwarf has bolometric absolute magnitude of +23.08 (this is about right)
