MST5: Particle acceleration and transport at the Sun and in the heliosphere

Session Organisers:

Mykola Gordovskyy (University of Manchester, UK), N.Bian, V.Nakariakov


Acceleration of particles in flares and other explosive events and their transport in the solar atmosphere and heliosphere remains a major problem of solar and solar-terrestrial physics. Despite the significant progress made in the last decades, there are number of outstanding issues such as the mechanisms behind the huge numbers of non-thermal electrons derived from hard X-ray observations and the role of energetic ions in flares. In recent years, various space missions and ground-based instruments provided substantial volume of high-quality multi-wavelength data. The goal of this session is to review recent observational results and to discuss how to adopt theoretical models to the tight constrains imposed by these observations.

The session will focus on correlative analysis of simultaneous hard X-ray, gamma-ray and radio observations of non-thermal particles in the corona. In addition, we will discuss how to connect the results of remote and in-situ observations related to the high-energy particles in the heliosphere with the particle acceleration in the corona.

Although this session will concern the recent progress made in the field of particle acceleration at the Sun and transport in the heliosphere, it will also include a discussion of the role of future missions/instruments in solving the problem of energetic particles.
