DESCRIPTION:Speakers: Salvatore Luigi Guglielmino (Istituto Nazionale di A
 strofisica (INAF))\n\nFocus Meeting 3\, held during the IAU General Assemb
 ly 2027 in Rome\n \nAbstract\nUnderstanding how magnetic fields connect a
 nd interact across the solar and stellar atmospheres is a central challeng
 e in modern astrophysics. The chromospheric–coronal interface is key to 
 explaining how energy and mass are transported\, stored\, and released in 
 these environments. This FM will bring together observers and modelers to 
 address the physics governing this complex region\, where magnetic restruc
 turing\, heating\, and dynamic events originate. \nRecent advances in high
 -resolution spectropolarimetry\, coronal magnetic-field measurements\, and
  multi-temperature spectroscopy now allow us to probe this interface with 
 unprecedented detail\, linking fine-scale plasma dynamics to large-scale m
 agnetic connectivity. Multi-vantage observations provide a global framewor
 k connecting the interface to the solar wind and guiding the interpretatio
 n of exoplanetary environments. With major active and upcoming facilities\
 , including DKIST\, Solar Orbiter\, MUSE\, Solar-C\, and the European Sola
 r Telescope\, it is timely to synthesize progress and define future direct
 ions in understanding chromosphere–corona magnetic coupling in the Sun a
 nd other stars. \nKey Focus Meeting Topics\n\nRecent advances in spectropo
 larimetric observations of the chromosphere and prospects for routine coro
 nal magnetic field measurements (solar and stellar contexts)\, including n
 ovel inversion techniques and their comparison and validation with numeric
 al models.\nFundamental processes of coronal heating and solar wind accele
 ration: observational evidence and numerical modelling\, and implications 
 for stellar winds in cool stars.\nThe role of magnetic connectivity in des
 tabilizing the atmosphere\, flares\, eruptions\, and space weather in the 
 solar system and exoplanetary systems.\nThe chromosphere–coronal magneti
 c connectivity as an interface between the dynamo and the interplanetary m
 agnetic field.\nFuture developments in instrumentation and observational s
 trategies.\n\n \n\nhttps://indico.ict.inaf.it/event/3653/
