One class of these objects was discovered when an expected titanium dioxide absorption band was not found. These objects have fairly consistent radii because light ones are limited by Coulomb pressure, while heavier ones are limited by electron degeneracy pressure. Divided into classes like L, T, and Y, these objects can be identified via the presence of methane, and the majority of them exhibit a lithium line. These objects must be fully convective, with no difference in composition at different depths. For 10 points, name these objects too small to maintain continuou
