The AMADEUS experiment investigates the low energy interaction of negative kaons with nucleons and light nuclei, aiming to solve longstanding open problems in the non-perturbative strangeness QCD sector. We take advantage of the low momentum ($p_K\sim$127 MeV/c) almost monochromatic charged kaons produced by the DA$\Phi$NE collider, in order to study the K$^-$ hadronic capture in the materials of the KLOE detector. The experimental data corresponds to the 1.64 fb$^-1$ luminosity of the 2004-2005 KLOE data taking campaign, which contains high statistics samples of K$^-$ nuclear captures (both at-rest and in-flight) in H, ${}^4$He, {}^9$Be and {}^12$C. We will present the results obtained from the analysis of hyperon-pion correlated production, to explore the behaviour of Y$^*$ resonances in nuclear environment. The investigation of $K^-$-multi nucleon capture and bound states formation through the decay in hyperon-proton, deuteron, and triton will be shown as well.
