In these proceedings, we present measurements of open bottom hadron production through multiple decay channels in Au + Au collisions at s NN = 200 GeV by the STAR experiment. Specifically, measurements of nuclear modification factors for electrons, J / ψ , and D 0 from open bottom hadron decays, enabled by the Heavy Flavor Tracker, are shown. A large suppression for non-prompt J / ψ and non-prompt D 0 are observed at high transverse momenta. On the other hand, there seems to be less suppression for electrons from bottom hadron decays than for those from charm hadron decays at ∼ 2 σ significance level.
