Call for abstracts – COSPAR session D2.3 “Magneto-plasma structures, streams and flows in the heliosphere”

Dear all,

We invite colleagues who are planning to attend the 46th COSPAR Scientific Assembly (Florence, Italy, 1 – 9 August 2026) to consider submitting abstracts to Session D2.3 “Magneto-plasma structures, streams and flows in the heliosphere”.

The abstract submission deadline has been extended to next Friday, 20 February.

Conference information is available and abstract submission is possible via the meeting website:
https://cospar2026.org/

More details on this session are available below and at this link: https://www.cospar-assembly.org/admin/session_cospar.php?session=1444

On behalf of the Scientific Organizing Committee of Session D2.3,

COSPAR-26-D2.3: Magneto-plasma Structures, Streams and Flows in the Heliosphere

The heliosphere contains various structures both originated from the Sun and formed directly in the solar wind. A common feature of magneto-plasma objects is their contribution to the nonlinear energy cascade and the ability to produce other structures, leading to the development of dynamical processes that make the solar wind an inhomogeneous medium in which turbulence and intermittency coexist with structuring and regularity.
Streams, flows, shocks, current sheets, and magnetic islands/flux ropes are important sources of particle acceleration and sites of magnetic reconnection. These structures can also be geoeffective and cause hazardous space weather effects.

We invite space physicists to share their recent results in studying
– interplanetary coronal mass ejections (ICMEs) and their solar sources,
– co-rotating/stream interaction regions (CIRs/SIRs) and coronal holes,
– current sheets of various origins, including the heliospheric current sheet (HCS),
– flux ropes/plasmoids/blobs/magnetic islands,
– magnetic holes, discontinuities, compressive plasma fluctuations, and boundaries of plasma structures,
– interplanetary and bow shocks,
and related processes.
Contributions discussing theoretical aspects, modelling, and observations are welcome.
