We report on the measurements of production of various charmed hadrons in Au+Au collisions at $\sqrt{s_{\rm{NN}}}$ = 200 GeV (including $D^{0}(\overline{D^{0}})$ and $\Lambda_{c}^{\pm}$) obtained via topological reconstruction, utilizing…
We present the measurements of $D^0$ and $D^*$ in p+p and $D^0$ in Au+Au collisions via hadronic decays $D^{0}\rightarrow K^{-}\pi^{+}$, $D^{*+}\rightarrow D^{0}\pi^{+}\rightarrow K^{-}\pi^{+}\pi^{+}$ in mid-rapidity $|y|<1$ at…
We present first results on D^0 meson production via direct reconstruction of its hadronic decay channel D^0->K pi in minimum bias Au+Au collisions at sqrt(s_(NN))=200 GeV with p_T up to ~3 GeV/c. Single electron spectra with 1<p_T<4 GeV/c…
Heavy quarks are a unique probe to study the medium produced in ultra-relativistic heavy ion collisions. The dominant process of charm quark production at RHIC is believed to be initial gluon fusion which can be calculated in the…
We report the first measurement of charmed-hadron ($D^0$) production via the hadronic decay channel ($D^0\rightarrow K^- + \pi^+$) in Au+Au collisions at $\sqrt{s_{_{\mathrm{NN}}}}$ = 200\,GeV with the STAR experiment. The charm production…
We report on the measurement of D meson production from the analysis of their hadronic ($D^0\to K\pi$) and semileptonic ($D\to \mu+X$, $D\to e+X$) decays in $\sqrt{s_{NN}}$=200 GeV Au+Au collisions. The transverse momentum ($p_T$) spectra…
We present the first comprehensive measurement of $D^{0}, D^{+}, D^{*+}$ and their charge conjugate states at mid-rapidity in $d$+Au collisions at $\sqrt{s_{_{NN}}}$=200 GeV using the STAR TPC. The directly measured open charm multiplicity…
We report measurements of charmed-hadron ($D^{0}$, $D^{*}$) production cross sections at mid-rapidity in $p$ + $p$ collisions at a center-of-mass energy of 200 GeV by the STAR experiment. Charmed hadrons were reconstructed via the hadronic…

We report on measurements of open charm production through both hadronic and semi-leptonic decay channels in $\sqrt{s_{NN}}$ = 200 GeV heavy ion collision at the STAR experiment at RHIC. We compare experimental results to theoretical…
The charm production is sensitive to early dynamics of the created system in RHIC heavy ion collisions. Dominant process of charm quarks production at RHIC is believed to be initial gluon fusion which can be calculated in the perturbative…

We report measurements of charmed hadron production from hadronic ($D^{0}\rightarrow K\pi$) and semileptonic ($\mu$ and $e$) decays in 200 GeV Au+Au collisions at RHIC. Analysis of the spectra indicates that charmed hadrons have a different…
We present a selection of recent heavy flavor results from the STAR experiment. Measurements of $D^0$ and $D^*$ meson production in $\sqrt{s}$=200 and 500 GeV p+p, as well as in $\sqrt{s_{NN}}$=200 GeV d+Au, Au+Au and 193 \GeV U+U…
We present analysis of J/$\psi$ production over the range $-1.0 < \eta < 4.2$ in p+p and d+Au collisions using di-electron data taken during the 2008 run with the STAR experiment at Brookhaven National Laboratory. STAR's unique forward…
