In these proceedings, we present measurements of open bottom hadron production through multiple decay channels in Au+Au collisions at [Formula: see text] = 200 GeV by the STAR experiment. Namely, measurements of nuclear modification factors for electrons, [Formula: see text], and [Formula: see text] from open bottom hadron decays are shown. The decay products are topologically identified utilizing the Heavy Flavor Tracker, a silicon vertex detector installed at STAR during the period of 2014 - 2016. It enables precise reconstruction of displaced decay vertices. The results show large suppression for non-prompt [Formula: see text] and non-prompt [Formula: see text] at high transverse momenta, and indicate less suppression for electrons from bottom hadron decays than for those from charm hadron decays at [Formula: see text] significance level.

Charm quarks are primarily produced at the early stages of ultra-relativistic heavy-ion collisions and can therefore probe the quark-gluon plasma throughout its whole evolution. Final-state open-charm hadrons are commonly used to experimentally study the charm quark interaction with the medium. Thanks to the excellent secondary vertex resolution provided by the Heavy Flavor Tracker, STAR is able to directly reconstruct D ± , D 0 , D s , and Λ c ± via their hadronic decay channels. The topological cuts for signal extraction are optimized using supervised machine learning techniques. In these proceedings, we present an overview of recent open charm results from the STAR experiment. The nuclear modification factors of open-charm mesons and Λ c ± /D 0 ratio are shown as functions of transverse momentum and collision centrality.
