What surface temperature range characterizes the T spectral class among Brown Dwarfs?
Answer
Between 550 K and 1,300 K
Brown Dwarfs evolve by continuously cooling and transition through several spectral classes too cool for the standard OBAFGKM sequence, specifically L, T, and Y classes. The T spectral class represents objects that are significantly cooler than M-stars, where the presence of methane becomes prominent in their spectral analysis, shifting their peak emission into the infrared spectrum. The defined surface temperature range associated with these T dwarfs is considerably low, spanning approximately 550 Kelvin up to 1,300 Kelvin. The coolest objects in this sequence are the Y dwarfs, which can have temperatures hovering near 250 K, comparable to a cold winter day on Earth.
