Dear Colleague,

The registration deadline has been extended to 12 April 2021 for the Royal Astronomical Society Specialist Discussion Meeting on Friday, 14 May 2021 (https://ras.ac.uk/events-and-meetings/ras-meetings/mhd-oscillations-and-waves-photosphere-corona). The topic is “MHD oscillations and waves from the photosphere to the corona”.

The vast presence of MHD waves and oscillations in the solar atmosphere is now unquestionable. However, it is still an open question as to how these waves and oscillations contribute to the heating of the solar atmosphere and the acceleration of the solar wind. A range of new instrumentation including e.g. the PSP, DKIST and Solar Orbiter, have recently become available providing us data with unprecedented resolution observed from close to the Sun to the Earth for studying MHD oscillations and waves.

Discussions will take place around topics including but not limited to: the propagation of waves from the lower to the upper solar atmosphere; the application of solar magneto-seismology (SMS) to structuring in the atmosphere of the Sun; the detection of MHD waves and oscillations in the solar atmosphere and interplanetary space; and the prospects for major advances using the next generation of solar instrumentation.

Hereby, we cordially invite colleagues to contribute to and participate in the discussions. We also encourage all those interested to present their related SUCs or specific observing sequences that would help to achieve the wave-related science goals with the upcoming 4-m class solar telescopes.

The meeting will be hosted online. It will consist of a series of invited and contributed talks together with discussions. Invited speakers include Dr. Anne-Marie Broomhall (Warwick), Prof. Hui Tian (PKU), and Prof. Manuel Collados (IAC, TBC). Depending on the number of contributions we may hold a virtual poster discussion.

Online registration is now open until 12 April 2020 via

We invite abstract submissions to the session entitled ‘Chromospheric dynamics and energy transport’ at the UK National Astronomy Meeting(19th-23rd July 2021)
https://nam2021.org/science/abstract-submission

The solar chromosphere is a challenging region to study from both theoretical and observational standpoints. Effects such as non-equilbirium ionisation, non-Local Thermal Equilibrium, 3D scattering effects, and partial redistribution of frequencies are often critical to model and interpret observed features. Moreover, this region is a crucial for understanding the Sun’s atmosphere since it acts as a conduit for energy, connecting the pressure dominated photosphere, and the magnetically dominated corona, as well as acting as in interface with the corona that can influence coronal heating.

The complexity of the solar chromosphere requires the development of new observational and numerical techniques that untangle the physics of this tumultuous region. This session will address these issues, presenting the latest techniques to accurately stitch together then science of the corona and the photosphere by analysing the dynamics and energy transport through the chromosphere. With the new generation of satellites and ground based telescopes looming, launching and preparing for first light, it is a fruitful time for both modeling and observing new behaviors in features such as fibrils, spicules, pores, vortices, and jets, as well as events like flares, Ellerman bombs and UV bursts.

We would like to encourage abstract submission to the NAM2021 session entitled ‘Modelling of the solar atmosphere: topics beyond the magnetohydrodynamic description’

Observations of the solar atmosphere reveal many phenomena that cannot be explained by simple magnetohydrodynamic (MHD) modelling alone. In such cases, it is necessary to extend our fundamental equations beyond ideal MHD to accurately understand energy release and transport. Extensions of MHD can fundamentally change the dynamics, leading to additional energy dissipation, enhanced reconnection rates and particle acceleration. Non-MHD effects are important throughout the solar atmosphere and encompass a wide range of physical effects, including (but not limited to): partial-ionisation, kinetic effects, radiative losses, and thermal conduction. Consequences of such effects are observed and understanding the role of such effects will become increasingly important in interpreting results from the current and next generation of instruments, e.g., Parker Solar Probe, Solar Orbiter, DKIST & EST. In this session, we bring together experts in observations and numerical modelling to present consequences of, advances in, and open questions of physics beyond the standard MHD description.

Abstract submission is now open: https://nam2021.org/science/abstract-submission

We invite abstract submissions from the Solar Physics community for a session on ‘Wave-Particle Interactions in Space and Astrophysical Plasmas’ at NAM 2021.

The session abstract is included below, and invited speakers are Francesco Valentini (Università della Calabria), Wen Li (Boston University), and Irina Zhuravleva (University of Chicago). Abstract deadline is Friday 30 April 2021 at 1700 UTC.

Session abstract:
Wave-particle interactions are an essential process in plasmas across our solar system and in astrophysical bodies that governs plasma heating and the transfer of energy between particles and electromagnetic fields. For example, EMIC waves and whistler mode waves play central roles in radiation belt acceleration and loss, Landau-damping of kinetic Alfvén waves is a key candidate to explain solar-wind heating, and heat-flux instabilities are crucial for the energy transfer in the intracluster medium. These interactions span a wide range of spatial scales: the fundamental interaction and wave growth take place on ion and electron scales but cause large-scale changes in the entire plasma population. Furthermore, the large-scale structure and plasma properties shape the propagation of wave energy and determine where wave-particle interactions occur.
This session aims to bring together researchers from the solar, terrestrial, planetary, and astrophysics communities to evaluate the breadth of interactions and investigate similarities and differences in wave-particle interactions. The multi-scale nature of wave-particle interactions and the variation of their characteristics for different plasma regimes will be explored. We welcome contributions from theoretical, modelling and observational perspectives.

We would like to invite abstract submissions to the UK National Astronomy Meeting 2021 session “Space weather and plasma processes: From the Sun to the Earth”, which is scheduled for the afternoons of Thursday 22nd and Friday 23rd July 2021.

Theory and numerical modelling have an important role in understanding the dynamic plasma processes which begin at the Sun and drive phenomena throughout the heliosphere. On the other hand, space weather modelling aims to develop operational models of this vast complex system, representing its effects closer to real-time while retaining the underlying physics.

Therefore, one of the key aspects of this cross-disciplinary session is to provide insight into the complementary modelling approaches to study and advance our understanding of related plasma environments in the Sun-Earth system. Furthermore, to reveal new prediction techniques which are able to refine our forecasting skills and capabilities of Solar Dynamics, Space Weather and Space Climate processes.

We welcome presentations from the scale of individual processes to the coupling between physical systems, in the fields of solar, heliospheric, magnetospheric and ionospheric physics. We encourage contributions on a variety of research methodologies, including the application of techniques drawn from other disciplines. We hope to see submissions ranging from observations and theory to numerical, statistical and machine learning modelling, in order to foster collaborations across communities.

NAM 2021 will take place online (hosted by the University of Bath) on 19th – 23rd July 2021.

Abstract submission is now open: https://nam2021.org/science/abstract-submission
