Comparison of the Scaling Properties of EUV Intensity Fluctuations in Coronal Hole and Quiet-Sun Regions
Ana Cristina Cadavid, Mari Paz Miralles, Kristine Romich
Using detrended fluctuation analysis (DFA) and rescaled range (R/S) analysis, we investigate the scaling properties of EUV intensity fluctuations of low-latitude coronal holes (CHs…
Multifractal Solar EUV Intensity Fluctuations and their Implications for Coronal Heating Models
Ana Cristina Cadavid, Yeimy J. Rivera, John K. Lawrence +3
We investigate the scaling properties of the long-range temporal evolution and intermittency of SDO/AIA intensity observations in four solar environments: an active region core, a…
Heating Mechanisms for Intermittent Loops in Active Region Cores from AIA/SDO EUV Observations
A. C. Cadavid, J. K. Lawrence, D. J. Christian +2
We investigate intensity variations and energy deposition in five coronal loops in active region cores. These were selected for their strong variability in the AIA/SDO 94 Å intensi…
Observed Effect of Magnetic Fields on the Propagation of Magnetoacoustic Waves in the Lower Solar Atmosphere
J. K. Lawrence, A. C. Cadavid
We study Hinode/SOT-FG observations of intensity fluctuations in Ca II H-line and G-band image sequences and their relation to simultaneous and co-spatial magnetic field measuremen…
Rapid Fluctuations in the Lower Solar Atmosphere
J. K. Lawrence, A. C. Cadavid, D. J. Christian +2
The Rapid Oscillations in the Solar Atmosphere (ROSA) instrument reveals solar atmospheric fluctuations at high frequencies. Spectra of variations of the G-band intensity (IG) and…
Space-Time Distribution of G-Band and Ca II H-Line Intensity Oscillations in Hinode/SOT-FG Observations
J. K. Lawrence, A. C. Cadavid
We study the space-time distributions of intensity fluctuations in 2 - 3 hour sequences of multi-spectral, high-resolution, high-cadence broad-band filtergram images (BFI) made by…
