Tensor Gaussian Process with Contraction for Multi-Channel Imaging Analysis
Hu Sun, Ward Manchester, Meng Jin +2
Multi-channel imaging data is a prevalent data format in scientific fields such as astronomy and biology. The structured information and the high dimensionality of these 3-D tensor…
What Sustained Multi-Disciplinary Research Can Achieve: The Space Weather Modeling Framework
Tamas I. Gombosi, Yuxi Chen, Alex Glocer +15
MHD-based global space weather models have mostly been developed and maintained at academic institutions. While the "free spirit" approach of academia enables the rapid emergence a…
Tracking the Source of Solar Type II Bursts through Comparisons of Simulations and Radio Data
Alexander M. Hegedus, Ward B. Manchester, Justin C. Kasper
The most intense solar energetic particle events are produced by coronal mass ejections (CMEs) accompanied by intense type II radio bursts below 15 MHz. Understanding where these t…
Predicting solar flares with machine learning: investigating solar cycle dependence
Xiantong Wang, Yang Chen, Gabor Toth +7
A deep learning network, Long-Short Term Memory (LSTM) network, is used in this work to predict whether the maximum flare class an active region (AR) will produce in the next 24 ho…
Interpreting LSTM Prediction on Solar Flare Eruption with Time-series Clustering
Hu Sun, Ward Manchester, Zhenbang Jiao +2
We conduct a post hoc analysis of solar flare predictions made by a Long Short Term Memory (LSTM) model employing data in the form of Space-weather HMI Active Region Patches (SHARP…
Solar Flare Intensity Prediction with Machine Learning Models
Zhenbang Jiao, Hu Sun, Xiantong Wang +4
We develop a mixed Long Short Term Memory (LSTM) regression model to predict the maximum solar flare intensity within a 24-hour time window 024, 630, 1236 and 24$…
Identifying Solar Flare Precursors Using Time Series of SDO/HMI Images and SHARP Parameters
Yang Chen, Ward B. Manchester, Alfred O. Hero +7
We present several methods towards construction of precursors, which show great promise towards early predictions, of solar flare events in this paper. A data pre-processing pipeli…
Extended MHD modeling of the steady solar corona and the solar wind
Tamas I. Gombosi, Bart van der Holst, Ward B. Manchester +1
The history and present state of large-scale magnetohydrodynamic (MHD) modeling of the solar corona and the solar wind with steady or quasi-steady coronal physics is reviewed. We p…
Eruptive Event Generator Based on the Gibson-Low Magnetic Configuration
Dmitry Borovikov, Igor V. Sokolov, Ward B. Manchester +2
Coronal Mass Ejections (CMEs), a kind of energetic solar eruptions, are an integral subject of space weather research. Numerical magnetohydrodynamic (MHD) modeling, which requires…
Threaded-Field-Lines Model for the Low Solar Corona Powered by the Alfven Wave Turbulence
Igor V. Sokolov, Bart van der Holst, Ward B. Manchester +6
We present an updated global model of the solar corona, including the transition region. We simulate the realistic tree-dimensional (3D) magnetic field using the data from the phot…
MHD Waves and Coronal Heating: Unifying Empirical and MHD Turbulence Models
Igor V. Sokolov, Bart van der Holst, Rona Oran +6
We present a new global model of the solar corona, including the low corona, the transition region and the top of chromosphere. The realistic 3D magnetic field is simulated using t…
Magnetic Effects Change Our View of the Heliosheath
M. Opher, P. C. Liewer, M. Velli +5
There is currently a controversy as to whether Voyager 1 has already crossed the Termination Shock, the first boundary of the Heliosphere. The region between the Termination Shock…
Magnetic Effects at the Edge of the Solar System: MHD Instabilities, the de Laval nozzle Effect and an Extended Jet
M. Opher, P. C. Liewer, M. Velli +6
To model the interaction between the solar wind and the interstellar wind, magnetic fields must be included. Recently Opher et al. 2003 found that, by including the solar magnetic…
