Exploring Magnetic Reconnection in the Collisional Ionosphere of Mars With MAVEN

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract Magnetic reconnection in collisional plasmas has been widely studied in solar and laboratory plasma disciplines, but in situ measurements in space plasmas have rarely been utilized to explore this reconnection regime. Here we study collisional effects on magnetic reconnection in the Martian ionosphere by analyzing in situ data obtained by the ...

Explosive Chromospheric Evaporation Driven by Nonthermal Electrons around One Footpoint of a Solar Flare Loop [PDF]

, 2017
We explore the temporal relationship between microwave/hard X-ray (HXR) emission and Doppler velocity during the impulsive phase of a solar flare on 2014 October 27 (SOL2014-10-27) that displays a pulse on the light curves in the microwave (34 GHz) and ...

Radiative Response to Large Decline in Anthropogenic Emissions From China Between 2008 and 2016 Is Modified by Simultaneous Biomass Burning Emission Changes

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 22, 28 November 2025.
Abstract The recent large reduction in anthropogenic aerosol emissions across China has improved China's air quality but has potential consequences for climate forcing. This sharp reduction in anthropogenic emissions has occurred against a background influenced by changing regional biomass burning emissions over a similar period of time.

A Data-constrained Magnetohydrodynamic Simulation of Successive X-class Flares in Solar Active Region 13842. II. Dynamics of the Solar Eruption Associated with the X9.0 Solar Flare

The Astrophysical Journal
Active region NOAA 13842 produced two successive solar flares: an X7.1-class flare on 2024 October 1, and an X9.0-class flare on 2024 October 3. This study continues our previous simulation work that successfully reproduced the X7.1-class solar flare. In

A Peculiar Feature of the First Ionization Potential Effect Before a Solar Flare Impulsive Phase Observed by MSS-1B, CHASE, and SDO

The Astrophysical Journal
The impulsive phase of solar flares is often accompanied by the depletion of the elements with low first ionization potential (FIP), whose abundance decreases from the coronal level to the photospheric level, and then recovers back to the coronal level ...
