dwarf greater than 1000 Kelvin    dstar  main sequence starStar with mass equal to or less than that of the sun. More generally, any star on or below the main sequence in the Hertzprung-Russell diagram.V
G starcooler than G25000 to 6000 K   yellowish late star   Yellowish star in which the H and K lines of Ca II have become dominant and in which a tremendous profusion of spectral lines of both neutral and ionized metals, particularly iron, begins to show. The Balmer lines of hydrogen are still recognizable. Examples are the Sun and Capella. 
T Tauri starcooler than G2greater than 1000 Kelvin 0.2 magnitudes or greatersome difficulty in distinguishing between various kinds  emission line star

  4. V 335, V 336, etc., when the double letter designations are exhausted
within a period of decadesnebular variableAlso called T Tauri variable, a type of variable star of spectral classification F, G or K (giants above the main sequence on the Hertzsprung-Russell diagram) that loses an appreciable proportion of its mass in its (irregular) more luminous periods, and is thus surrounded by volumes of gas and dust.
