Abstract: | Research into the heliospheric structure and its relation to the solar boundary is at an impasse. After successful predictions
by Parker about the zeroth-order behavior of the heliospheric magnetic field and the solar wind, the heliospheric community
struggles to make substantive progress toward a predictive model describing the connections between the Sun and its space
environment, between the closed corona and the open corona extending to the planets. This is caused by our lack of understanding
of the basic processes heating the corona and transporting open magnetic field. We detail the models used to describe this
connectivity, from potential field source surface models to full MHD techniques. We discuss the current limitations of both
approaches. Finally, we address a recent attempt to advance our understanding beyond these limitations. At this point in time
the proposed theory remains controversial in the community, but it addresses important shortcomings of current approaches
outlined above. |
