Numerical simulations of a flux rope ejection [PDF]

open access: yes, 2015
Coronal mass ejections (CMEs) are the most violent phenomena observed on the Sun. One of the most successful models to explain CMEs is the flux rope ejection model, where a magnetic flux rope is expelled from the solar corona after a long phase along ...

On ion-cyclotron-resonance heating of the corona and solar wind [PDF]

open access: yesNonlinear Processes in Geophysics, 2003
This paper concisely summarizes and critically reviews recent work by the authors on models of the heating of the solar corona by resonance of ions with high-frequency waves (up to the proton cyclotron frequency).

Compound Meteorological and Hydrological Hot‐Dry and Hot‐Wet Extremes Over Global Land Areas: Spatiotemporal Changes, Attribution, and Drivers

open access: yesInternational Journal of Climatology, EarlyView.
The changes in joint return period of compound meteorological hot‐dry (CMHHE) and hot‐wet (CMHWE) and compound hydrological hot‐dry (CHHDE) and hot‐wet (CHHWE) extremes were attributed to changes in associated univariate extremes and their dependence.

The investigation of quasi-separatrix layers in solar magnetic fields [PDF]

open access: yes, 2011
The structure of the magnetic field is often an important factor in many energetic processes in the solar corona. To determine the topology of the magnetic field features such as null points, separatrix surfaces, and separators must be found.

Modelling the total solar eclipse in 2024 with COCONUT

open access: yesAstronomy & Astrophysics
Context. Coronal modelling is crucial for a better understanding of solar physics and heliophysics. Accurate plasma conditions at the outer boundary of a solar corona lead to more precise space weather predictions.

Multiwavelength Observations of a B-class Flare Using XSM, AIA, and XRT

open access: yesThe Astrophysical Journal, 2023
We present multiwavelength observations by Chandrayaan-2/Solar X-ray Monitor, Solar Dynamics Observatory/Atmospheric Imaging Assembly, and Hinode/X-Ray Telescope (XRT) of a B-class flare observed on 2021 February 25, originating from an active region (AR

Ozonation as a promising approach to improve stored rice quality in Ghana

open access: yesJSFA reports, EarlyView.
Abstract Background Two species of rice pests that are responsible for postharvest losses, the rice weevil (Sitophilus oryzae) and the Angoumois moth (Sitotroga cerealella), are major destructive pests responsible for paddy grain deterioration. A benchtop custom‐built model of ozone‐generating equipment from ozone generator DKM‐10GY, producing 2000 ppm

A Comprehensive Model of the K-coronal Spectrum for the Inference of Electron Temperature and Bulk Flow Velocity in the Corona

open access: yesThe Astrophysical Journal Supplement Series
The electron temperature of the corona is one of the key physical parameters which reflect the complexity of coronal-heating processes. L. E. Cram was the first to show that the K-coronal spectrum, produced by the scattering of the photospheric spectrum ...
