Abstract
We report on the latest measurements of the production of mesons in heavy-ion collisions from the STAR experiment at RHIC. New measurements of the nuclear modification factors of the (1S+2S+3S) and (1S) states in U+U collisions at = 193 GeV are presented as a function of the number of participants () in the collisions. In addition, the suppression of (1S) and (2S+2S) is presented versus the quark-antiquark binding energy. Preliminary results on Upsilon suppression in Au+Au collisions at = 200 GeV, reconstructed via the dimuon channel, are also reported.
