Andrea Bellini

Andrea Bellini is a Researcher at the Space Telescope Science Institute (STScI), specializing in observational astronomy with Hubble and James Webb Space Telescopes. His work centers on high-precision astrometry of star clusters across the Milky Way and Magellanic Clouds, focusing on internal kinematics, multiple stellar populations, and cluster dynamics.

Bellini's research spans globular clusters (e.g., Omega Centauri, 47 Tucanae, NGC 2808), open clusters, and dwarf galaxies. He pioneers proper motion measurements to study stellar rotation, black holes, planetary nebulae membership, and dark matter distributions. His methodology integrates HSTPROMO and oMEGACat survey data with cutting-edge JWST observations.

Recent publications reveal three dominant research thrusts: (1) Kinematic analysis of cluster populations using multi-epoch HST data, (2) JWST-enabled studies of low-mass stellar objects and intracluster media, and (3) Development of Roman Space Telescope instrumentation tools. His work consistently demonstrates leadership in large collaborations like CARMA and HST legacy programs.

Bellini actively contributes to mission-critical software development, including the Astronomer's Proposal Tool for the Roman Space Telescope and desktop simulators. His research directly enables breakthroughs in galactic archaeology and stellar evolution through precise dynamical modeling of cluster systems.
