Review of Machine Learning Models for Solar Energetic Particle Prediction
Spiridon Kasapis, Pouya Hosseinzadeh, Kathryn Whitman +73
Solar energetic particle (SEP) events have attracted increasing attention due to their significant radiation hazards for aviation, spacecraft electronics, and human missions beyond…
Inference of chromospheric magnetic fields in a sunspot derived from spectropolarimetry of Ca II 8542 A
Ali G. A. Abdelkawy, Abdelrazek M. K. Shaltout, M. M. Beheary +1
We analyze spectropolarimetric observations of the chromospheric Ca II 8542 A line taken by the Interferometric Bidimensional Spectrometer (IBIS) at the Dunn Solar Telescope. The d…
The chromospheric magnetic field in active regions derived from spectropolarimetry of Ca II 8542
Ali G. A. Abdelkawy, Abdelrazek M. K. Shaltout, M. M. Beheary
We analyze spectropolarimetric observations of the chromospheric Ca II 8542 line taken by the Interferometric Bidimensional Spectrometer (IBIS) at the Dunn Solar Telescope and phot…
The LTE solar abundance of neodymium
A. G. A. Abdelkawy, Abdelrazek M. K. Shaltout, M. M. Beheary +1
We study the solar photospheric abundance of singly ionized neodymium (Nd II) using high resolution spectroscopic data obtained by Fourier transform spectrograph (FTS). Based on th…
