We study the temperature dependence of bottomonium for temperatures in the range 0.4T(c) < T < 2.1T(c), using nonrelativistic dynamics for the bottom quark and full relativistic lattice QCD simulations for N-f = 2 light flavors on a highly anisotropic lattice. We find that the Y is insensitive to the temperature in this range, while the chi(b) propagators showa crossover from the exponential decay characterizing the hadronic phase to a power-law behavior consistent with nearly free dynamics at T similar or equal to 2T(c).
