The FASTSUM collaboration has a long-standing project examining hadronic properties using
anisotropic lattice QCD. We determine the spectral properties of bottomonia at finite temperature
using lattice NRQCD and describe how our newer simulations improve our control over systematic
errors. Motivated by these efforts, the temperature dependence of charm hadron masses is
determined where it is found that temperature effects can extend into the confining phase and that
some species remain stable deep past the pseudo-critical temperature.
