We present the analyses of single electrons from semileptonic bottom and charm hadron decays at mid-rapidity in sNN=200and54.4GeV Au+Au collisions (talk in Heavy-Flavor session III). The data at sNN=200GeV incorporate information from the Heavy Flavor Tracker which enables the topological separation of electrons originating from bottom and charm hadron decays. We report the first STAR measurements at sNN=200GeV of ν2 for bottom decay electrons as a function of pT and ν1 for charm decay electrons as a function of electron rapidity. Additionally, we present the improved measurements of heavy-flavor decay electron RAA and a new measurement of the ratio of RCP between bottom and charm decay electrons. Finally, we also report the measurement of non-photonic electron ν2 in sNN=54.4GeV data collected during the 2017 RHIC run.
