Dielectron continuum production from $\sqrt{s_{NN}}$ = 200 GeV p + p and   Au + Au collisions at STAR
  We present the first STAR dielectron measurement in 200 GeV p + p and Au + Au collisions. Results are compared to hadron decay cocktails to search for vector meson in-medium modification in low mass region and quark gluon plasma thermal radiation in the intermediate mass region. The $\omega \rightarrow e^{+}e^{-}$ spectra and the transverse mass distribution in the intermediate mass region are also discussed.
