A Statistical Study to Determine the Origin of Long-Duration Gamma-ray Flares
Lisa M. Winter, Valerie Bernstein, Nicola Omodei +1
Two scenarios have been proposed to account for sustained \,MeV gamma-ray emission in solar flares: (1) prolonged particle acceleration/trapping involving large-scale magne…
Comparing SSN Index to X-ray Flare and Coronal Mass Ejection Rates from Solar Cycles 22-24
Lisa M. Winter, Rick Pernak, K. S. Balasubramaniam
The newly revised sunspot number series allows for placing historical geoeffective storms in the context of several hundred years of solar activity. Using statistical analyses of t…
Type II and Type III Radio Bursts and their Correlation with Solar Energetic Proton Events
L. M. Winter, K. Ledbetter
Using the Wind/WAVES radio observations from 2010-2013, we present an analysis of the 123 decametric-hectometric (DH) type II solar radio bursts during this period, the associated…
Using the Maximum X-ray Flux Ratio and X-ray Background to Predict Solar Flare Class
Lisa M. Winter, K. Balasubramaniam
We present the discovery of a relationship between the maximum ratio of the flare flux (namely, 0.5-4 Ang to the 1-8 Ang flux) and non-flare background (namely, the 1-8 Ang backgro…
Estimate of Solar Maximum using the 1-8 ÅGeostationary Operational Environmental Satellites X-ray Measurements
L. M. Winter, K. S. Balasubramaniam
We present an alternate method of determining the progression of the solar cycle through an analysis of the solar X-ray background. Our results are based on the NOAA Geostationary…
Multiwavelength Observations of A0620-00 in Quiescence
C. S. Froning, A. G. Cantrell, T. J. Maccarone +17
[Abridged.] We present multiwavelength observations of the black hole binary system, A0620-00. Using the Cosmic Origins Spectrograph on the Hubble Space Telescope, we have obtained…
