Theoretical and experimental capabilities needed in the next decade are discussed.ELETTRONICOenArticlehttps://baas.aas.org/pub/2020n3i431/release/12019BAAS...51c.431OFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation
