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$…
Evidence of ammonium salts in comet 67P as explanation for the nitrogen depletion in cometary comae
K. Altwegg, H. Balsiger, J. -J. Berthelier +14
Cometary comae are generally depleted in nitrogen. The main carriers for volatile nitrogen in comets are NH3 and HCN. It is known that ammonia readily combines with many acids like…
Coupled MHD -- Hybrid Simulations of Space Plasmas
S. P. Moschou, I. V. Sokolov, O. Cohen +6
Heliospheric plasmas require multi-scale and multi-physics considerations. On one hand, MHD codes are widely used for global simulations of the solar-terrestrial environments, but…
High Resolution Finite Volume Method for Kinetic Equations with Poisson Brackets
Igor V. Sokolov, Haomin Sun, Gabor Toth +6
Simulation of plasmas in electromagnetic fields requires numerical solution of a kinetic equation that describes the time evolution of the particle distribution function. In this p…
The Surface Distributions of the Production of the Major Volatile Species, H2O, CO2, CO and O2, from the Nucleus of Comet 67P/Churyumov-Gerasimenko throughout the Rosetta Mission as Measured by the ROSINA Double Focusing Mass Spectrometer
Michael Combi, Yinsi Shou, Nicolas Fougere +12
The Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) suite of instruments operated throughout the over two years of the Rosetta mission operations in the vicinity…
Elemental and molecular abundances in comet 67P/Churyumov-Gerasimenko
Martin Rubin, Kathrin Altwegg, Hans Balsiger +18
Comets are considered to be some of the most pristine and unprocessed solar system objects accessible to in-situ exploration. Investigating their molecular and elemental compositio…
