In these proceedings, we present measurements of open bottom hadron production through multiple decay channels in Au + Au collisions at = 200 GeV by the STAR experiment. Specifically, measurements of nuclear modification factors for electrons, , and from open bottom hadron decays, enabled by the Heavy Flavor Tracker, are shown. A large suppression for non-prompt and non-prompt 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 ∼ significance level.
