Abstract
We present preliminary studies of bottomonia spectral functions at zero and finite temperature using quenched anisotropic lattices. The heavy quark is treated within Fermilab approach. We find no modification of the ηb and Υ states up to temperatures 2.3Tc while our study suggest dissolution of χb state at 1.15Tc.
