Abstract
The symposium will address critical gaps in solar and stellar physics, leveraging recent advancements and fostering collaboration between traditionally independent solar and stellar communities. The Scientific Organizing Committee comprises experts from renowned institutions worldwide, ensuring a diverse and comprehensive exploration of multi-scale solar and stellar activity. The symposium will strategically align with pivotal advancements in solar missions (ADITYA, CHASE) and ground-based instrumentation, offering a timely platform for knowledge exchange.  The programme will cover diverse themes, including observatories, energy release processes, magnetic variability, machine learning, and helio-asteroseismology, ensuring a comprehensive exploration of solar and stellar phenomena. Anticipation of support from the DynaSun HORIZON Project further validates the symposium's relevance, strengthening research links between South American and European communities in solar and heliophysics science.
