  We present pion-Xi correlation analysis in Au-Au collisions at sqrt(s_NN)=
200 GeV and sqrt(s_NN) = 62.4 GeV, performed using the STAR detector at RHIC. A
Xi*(1530) resonance signal is observed for the first time in Au-Au collisions.
Experimental data are compared with theoretical predictions. The strength of
the Xi* peak is reproduced in the correlation function assuming that pions and
Xis emerge from a system in collective expansion.
