Published in 2021 at "Icarus"

DOI: 10.1016/j.icarus.2021.114508

Abstract: Abstract Conditions in the ionosphere of Mars vary from solar minimum to solar maximum due to changes in the ionizing solar irradiance. Although changes in the main ionospheric layers, namely the M2 layer and the… read more here.

Published in 2021 at "Space Weather"

DOI: 10.1029/2020sw002690

Abstract: Although it is accepted that the electron density double peaks of the Equatorial Ionization Anomaly (EIA) generally merge into a single‐peak with increasing altitude and thus the signature of EIA becomes inconspicuous in the higher… read more here.

Published in 2025 at "Frontiers in Astronomy and Space Sciences"

DOI: 10.3389/fspas.2025.1568929

Abstract: Highly charged ions in the solar wind undergo charge exchange with neutral atoms in the Earth’s exosphere, particularly within the magnetosheath and cusps. This solar wind charge exchange process generates X-rays, which are expected to… read more here.

Published in 2024 at "Annales Geophysicae"

DOI: 10.5194/angeo-42-431-2024

Abstract: Abstract. Polar mesospheric summer echoes (PMSEs) are radar echoes that are measured in the upper atmosphere during the summer months and that can occur in several layers. In this study, we aimed to investigate the… read more here.
