Abstract: (arXiv)

We present STAR measurements of relative charm and bottom contributions to NPE from

p+p

collisions at

\sqrt{s}

= 200 and 500 GeV energies. We report the total bottom quark production cross section from p+p collisions at

\sqrt{s}= 200

GeV extracted from NPE spectrum and B to D ratios. We also present the NPE-hadron azimuthal correlations from

Au+Au

collisions at \sqrtsNN = 200 GeV from the 2010 RHIC run where we have collected high statistics data set with low photonic conversion background.
