Azimuthal anisotropy and femtoscopic measurements provide information about collectivity and dynamics of the created medium. Data from the BES enables STAR to search for the turn-on/off signatures of the Quark-Gluon Plasma (QGP), for the first-order phase transition, and to constrain various models. In midcentral collisions, the proton and net-proton slope parameter (dυ1=dy|y=0) shows a minimum between and 19.6 GeV. The pion and kaon femtoscopic radii are also measured as a function of transverse mass (mT ), centrality and collision energy, and showing that the system at high energies lives longer.
