- Chaos in N-body systems: Application to triple stars and Halley’s comet
- Abstract
- N-body simulations are used to study the dynamical evolution of planetary systems, star clusters, galaxies and large scale structure. These systems are often chaotic, in the sense that they are highly sensitive to initial conditions. In the first part of my talk, I focus on the growth of small numerical errors, to determine the reliability of N-body results, specifically those of chaotic triple systems. In the second part I study the growth of a small, physical perturbation in order to study the stability of the orbit of comet Halley.

- The Solar-C Mission: Current Status and Future Direction
- Abstract
-
Solar-C is a Japanese-led international solar observing mission designed to answer some of the most important questions in solar physics. Recent space missions revealed that the different parts of the magnetized solar atmosphere are essentially coupled and they have defined the spatial scales and temperature regimes that need to be observed in order to achieve a comprehensive physical understanding of this coupling. The science of Solar-C will greatly advance our understanding of the Sun, of basic physical processes operating throughout the universe, and of how the Sun influences the Earth and other planets in our solar system.
The Solar-C mission proposal was submitted to ISAS/JAXA in response to the JAXA AO for the first launch of the strategic medium-size (SM) mission together with the EPIC (European Participation In solar-C) proposal submitted to ESA, but neither of them was unfortunately successful. The ISAS/JAXA evaluation committee concluded that the working group should re-study the mission by intensifying its science with more affordable scheme of international collaboration.
Talking to NASA, we are going to start the discussion hopefully in the Joint Solar-C Science Definition Team (JSSDT) composed of scientific specialists who have been selected to represent the broad interests of the heliophysics research community. The primary role of the JSSDT is to develop and document scientific goals and priorities of a new potential multilateral Solar-C mission within the resources to be specified by the Agencies.
The Solar-C mission is now aiming primarily for the second SM launch scheduled in FY 2024 – 25 with its intensified science and possibly with the new international task shares for the new instrument configuration. - Facilitator
