Description
The elliptic flow ($v_{2}$) is the second Fourier coefficient of azimuthal distributions of produced particles in heavy-ion collisions. Measurements of identified particle $v_{2}$ is one of the most informative ways in studying the properties of hot and dense nuclear matter created in heavy-ion collisions.
In this poster, elliptic flow of identified hadrons (${\pi}^{\pm}$, ${K}^{\pm}$, $p$ , and $\bar{p}$) in $\sqrt{s_{NN}}$ = 7.7 and 9.2 GeV Au+Au collisions, data collected by the STAR experiment in the second phase of the beam energy scan (BES-II), will be presented. We will show $v_{2}$ as a function of $p_{T}$ for these particles in 0-80$\%$, 0-10$\%$, 10-40$\%$, and 40-80$\%$ centrality bins and compare to those from other collision energies. In addition, the number of constituent quark (NCQ) scaling in $v_{2}$ will be studied, and the $v_{2}$ results will be compared to different model calculations.
