Complex Magnetic Evolution and Magnetic Helicity in the Solar Atmosphere
Alexei A. Pevtsov
Solar atmosphere is a single system unified by the presence of large-scale magnetic fields. Topological changes in magnetic fields that occur in one place may have consequences for…
Cyclic and Long-term Variation of Sunspot Magnetic Fields
Alexei A. Pevtsov, Luca Bertello, Andrey G. Tlatov +3
Measurements from the Mount Wilson Observatory (MWO) are used to study the long-term variations of sunspot field strengths from 1920 to 1958. Following a modified approach similar…
The Build-up to Eruptive Solar Events Viewed as the Development of Chiral Systems
Sara F. Martin, Olga Panasenco, Mitchell A. Berger +4
When we examine the chirality or observed handedness of the chromospheric and coronal structures involved in the long-term build-up to eruptive events, we find that they evolve in…
Comparison of Ground- and Space-based Longitudinal Magnetograms
A. Pietarila, L. Bertello, J. W. Harvey +1
We compare photospheric line-of-sight magnetograms from the Synoptic Long-term Investigations of the Sun (SOLIS) vector spectromagnetograph (VSM) instrument with observations from…
Magnetic Connectivity between Active Regions 10987, 10988, and 10989 by Means of Nonlinear Force-Free Field Extrapolation
T. Tadesse, T. Wiegelmann, B. Inhester +1
Extrapolation codes for modelling the magnetic field in the corona in cartesian geometry do not take the curvature of the Sun's surface into account and can only be applied to rela…
Science Objectives for an X-Ray Microcalorimeter Observing the Sun
J. Martin Laming, J. Adams, D. Alexander +57
We present the science case for a broadband X-ray imager with high-resolution spectroscopy, including simulations of X-ray spectral diagnostics of both active regions and solar fla…
