Solar Orbiter/METIS

Author: Marco Romoli and the Metis Team Affiliation: University of Florence, Italy Abstract: METIS coronagraph is designed to observe the solar corona with an annular field of view from 1.5 to 2.9 degrees in the visible broadband (580-640 nm) and in the UV HI Lyman-alpha, during the Sun close approaching and high latitude tilting orbit[…]


The SWA plasma suite on board Solar Obiter

Author: Raffaella D’Amicis on behalf on the SWA team Affiliation: INAF/IAPS Rome Abstract: Solar Orbiter, scheduled to be launched in October 2018, will be the first spacecraft since Helios to sample the inner heliosphere at distances as close to the Sun as 60 solar radii. It will be equipped with both in-situ instruments significantly more[…]



Author: Silvano Fineschi Affiliation: INAF – Astrophysical Observatory of Torino Abstract: Proba-3 is ESA’s – and the world’s – first precision formation flying mission. A pair of satellites will fly together maintaining a fixed configuration as a ‘large rigid structure’ in space to prove formation flying technologies. The mission will demonstrate formation flying in the context[…]


The Latest Developments in Solar Dynamo: a key to solar/stellar magnetic activity and variability

Author: Rosaria Simoniello Affiliation: Geneva University, Chemin des Maillettes 51, 1290 Sauverny, Switzerland Abstract: The multitude of activity phenomena on the solar surface are related to magnetic fields believed to be driven by a dynamo mechanism acting in the tachocline. This global dynamo involves the generation and evolution of the largest features of the sun,[…]


Understanding SEP properties at 1 AU through neutron monitor data modeling

Authors: Plainaki[a][b], M. Laurenza[a], H. Mavromichalaki[b], M. Storini[a] Affiliation: [a]INAF-IAPS, Via del Fosso del Cavaliere, 00133, Rome, Italy [b]Nuclear and Particle Physics Section, Physics Dpt., National and Kapodistrian University of Athens, Greece Abstract: Ground-level enhancements (GLEs) are short-term increases of the cosmic ray intensity registered at the ground by particle detectors, such as ionization chambers,[…]


The ESA-JAXA BepiColombo Mission to Mercury On-board payload and Heliospheric Science Objectives

Author: Stefano Orsini Affiliation: IAPS-INAF Abstract: The BepiColombo mission to Mercury, an ESA-JAXA joint venture, is composed by two satellites. The first, the Mercury Planetary Orbiter (MPO, ESA) will operate along a low-altitude polar orbit (~ 480×1500 km); while the second, the Mercury Magnetospheric Orbiter (MMO, JAXA) will move along a polar orbit as well,[…]


The physical mechanisms that trigger coronal mass ejections

Author: Francesco Zuccarello Affiliation: Observatoire de Paris, Paris Abstract: Solar filaments are magnetic structures often observed in the solar atmosphere and consisting of plasma that is cooler and denser than their surroundings. They are visible for days – and even weeks – which suggests that they are often in equilibrium with their environment before erupting,[…]
