Abstract
In the present work we summarize the first achievements of the RockStar Group of the Department of Physics and Geology (at the University of Perugia, Italy), which is made of a strict collaboration between Physicists and Geologists on astrophysical and planetological studies. The RockStar Group acts on two research lines: (i) astrophysical modeling and (ii) mineralogical and geochemical studies of meteorites. In the first part of the article we review the recent results concerning the development of theoretical modeling of nucleosynthesis and mixing process in asymptotic giant branch. In the second part we report (1) the catalog of the Meteorite collection of University of Perugia and (2) major and trace elements mapping, performed through EPMA and LA-ICP-MS, of the Mineo pallasite, a unique sample hosted by the collection. The new data constrain the Mineo meteorite among the Main Group Pallasites and support the hypothesis of the “early giant impact” formation.
Highlights
Coupling the expertise from different scientific fields is nowadays mandatory to achieve new milestones, add knowledge and validate models

Summary
Coupling the expertise from different scientific fields is nowadays mandatory to achieve new milestones, add knowledge and validate models. In order to face cross-disciplines topics on astrophysical and planetological studies, a strict collaboration between Physicists and Geologists of the Department of Physics and Geology of the University of Perugia (Italy) has been set up naming this informal group RockStar Group. We describe main activities and results of the RockStar Group, both in astrophysical modelling and meteorite classification, with particular focus on new geochemical data of the Mineo pallasite, a unique sample re-discovered during the initial stages of RockStar Group activities. The activities of the RockStar Group are mainly focused on two research topics: (i) the development of theoretical modeling of nucleosynthesis and mixing processes in asymptotic giant branch (AGB) and (ii) the classification and the mineralogical-geochemical study of meteorites
