Online Advanced Study Program on Helicities in Astrophysics and Beyond
Magnetic helicity has been intensively studied over the recent few decades from observational, theoretical, and other aspects in Astrophysics, Solar Physics, Plasma and Fluid Dynamics, and Mathematics. There was a series of focused events such as Chapman Conference in Boulder in 1998, Helicity Thinkshops in China and Japan in 2009 https://sun.bao.ac.cn/old/meetings/HT2009/, 2013 https://sun.bao.ac.cn/old/meetings/HT2013/ and 2017 http://science-media.org/conference/23 , as well as the Program on Solar Helicities at NORDITA in 2019 https://indico.fysik.su.se/event/6548/ and many other. Given the current situation with the pandemic we are going to propose moving this activity online. Hereby, we would like to make it more appealing to broader audience beyond the existing community, and also acceptable for early age researchers and students. We aim for inviting to give online talks and lectures not only solar physicists but also experts in various fields who are interested in observational and theoretical studies of magnetic, kinetic and other helicities, in order to encompass the community for the interdisciplinary studies and to encourage wider audience including students to participate in it.
Topics to be communicated:
- Observations of magnetic fields in astrophysics and the relationship with the breakage of mirror symmetry in and above the solar atmosphere, interplanetary plasmas, galaxies, and other astrophysical bodies;
- The origin of magnetic helicity in the Sun, and its relationship with MHD processes below and above the photosphere, eruptions of solar flares and CMEs; magnetic helicity in the solar wind;
- The role of helicity invariants in the dynamo theory, MHD simulations, and magneto-convection in space and laboratory plasma and experiments;
- Relationship of the magnetic and kinetic helicities with turbulence and the fundamental topology of MHD flows;
- Mathematical properties of knotedness and chirality in topology, theoretical physics and applications.
The proposed schedule of the Program will be spread over approximately 8 weeks between September through November/December 2020 with one or two sessions per week. Each session can be formed of either one 60+ minute talk, or two 30-40 minute talks with complementary discussion. We expect at least 15 presentations of various formats over the Program. The timing of each session can be arranged by convenience of the speaker and the community with account of their time zones. Afterwards, the lecture materials, such as podcasts, presentations files (at least brief) may be published fully or partly online. If you would like to give a talk, please contact the Scientific Program Committee (SPC) by email email@example.com.
