Trigger Mechanism of Solar Subflares in a Braided Coronal Magnetic Structure

Sanjiv K. Tiwari, Caroline E. Alexander, Amy R. Winebarger +1

Fine-scale braiding of coronal magnetic loops by continuous footpoint motions may power coronal heating via nanoflares, which are spontaneous fine-scale bursts of internal reconnec…

On the Area Expansion of Magnetic Flux-Tubes in Solar Active Regions

Jaroslav Dudik, Elena Dzifcakova, Jonathan W. Cirtain

We calculated the 3D distribution of the area expansion factors in a potential magnetic field extrapolated from the high-resolution \textit{Hinode}/SOT magnetogram of a quiescent a…

Magnetic Flux Transport at the Solar Surface

J. Jiang, D. H. Hathaway, R. H. Cameron +3

After emerging to the solar surface, the Sun's magnetic field displays a complex and intricate evolution. The evolution of the surface field is important for several reasons. One i…

Impulsive energy release and non-thermal emission in a confined M4.0 flare triggered by rapidly evolving magnetic structures

Upendra Kushwaha, Bhuwan Joshi, Kyung-Suk Cho +3

We present observations of a confined M4.0 flare from NOAA 11302 on 2011 September 26. Observations at high temporal, spatial, and spectral resolution from Solar Dynamics Observato…

Near infrared spectroscopy of the type IIn SN 2010jl: evidence for high velocity ejecta

H. Jacob Borish, Chenliang Huang, Roger A. Chevalier +3

The Type IIn supernova SN 2010jl was relatively nearby and luminous, allowing detailed studies of the near-infrared (NIR) emission. We present 1 - 2.4 micron spectroscopy over the…

The Solar Meridional Circulation and Sunspot Cycle Variability

David H. Hathaway, Lisa Upton

We have measured the meridional motions of the magnetic elements in the Sun's surface layers since 1996 and find systematic and substantial variations. In general the meridional fl…

Deciphering Solar Magnetic Activity I: On The Relationship Between The Sunspot Cycle And The Evolution Of Small Magnetic Features

Scott W. McIntosh, Xin Wang, Robert J. Leamon +6

Sunspots are a canonical marker of the Sun's internal magnetic field which flips polarity every ~22-years. The principal variation of sunspots, an ~11-year variation in number, mod…

On the structure and evolution of a polar crown prominence/filament system

N. K. Panesar, D. E. Innes, D. J. Schmit +1

Polar crown prominences are made of chromospheric plasma partially circling the Suns poles between 60 and 70 degree latitude. We aim to diagnose the 3D dynamics of a polar crown pr…

Sparkling EUV bright dots observed with Hi-C

S. Regnier, C. E. Alexander, R. W. Walsh +12

Observing the Sun at high time and spatial scales is a step towards understanding the finest and fundamental scales of heating events in the solar corona. The Hi-C instrument has p…

Giant Convection Cells Found on the Sun

David H. Hathaway, Lisa Upton, Owen Colegrove

Heat is transported through the outermost 30% of the Sun's interior by overturning convective motions. These motions are evident at the Sun's surface in the form of two characteris…
