COFFIES Theme Workshop on the Flux Transport & Emergence (FT&E)

The COFFIES DRIVE Science Center is pleased to announce our first science-theme oriented virtual workshops on the first three Fridays of October. We aim to understand the solar cycle as the Consequence of Fields and Flows in the Interior and Exterior of the Sun (COFFIES). We welcome community participation in the discussions of science related to the Near-Surface Shear Layer (NSSL), the Tachocline, and Flux Transport & Emergence (FT&E). Zoom meetings will begin at 9 am PT on October 7, 14, and 21. Each session will review current understanding and provide time for brief contributed presentations.

We hope to include the greater solar physics community in our efforts to observe and model the physics of the generation, storage, and subsequent emergence of magnetic flux from the Sun’s deep interior to its visible surface. This workshop will be the first in a series of topical discussions with the goal of facilitating multidisciplinary collaboration and interaction between researchers interested in how the physics of magnetic flux transport through the solar interior and across the visible surface influences our understanding of the observed properties of the solar cycle dynamo.

We encourage participation with short contributions discussing new results and ideas, for observations and models, that may lead to a comprehensive view of flux emergence and transport, and its relevance for the solar dynamo.

Please send contributions to the FT&E Theme Baristas: Bill Abbett and Aimee Norton.
