Proton Temperature Anisotropy within the Interplanetary Coronal Mass Ejections Sheath at 1 au
The Astrophysical Journal Letters, 2023 The sheath plasma of interplanetary coronal mass ejections (ICMEs) is highly compressed, heated, turbulent, and magnetically intense relative to the ambient solar wind.

Energetics of a Solar Flare and a Coronal Mass Ejection Generated by a Hot Channel Eruption
The Astrophysical Journal, 2023 Hot channels (HCs) are prevalent in the solar corona and play a critical role in driving flares and coronal mass ejections (CMEs). In this paper, we estimate the energy content of an X1.4 eruptive flare with a fast CME generated by an HC eruption on 2011

Analysis of coronal mass ejections and solar flares
International Journal of Innovative Research and Growth, 2022 The Sun is the most conspicuous element in our nearby planet group and contains around 98% of the all out planetary group mass. In this work we have selected those CME events which are having velocity >=500 Km/s with an apparent width of 3600 during the period from 2008-2019 (SC24).Within this time frame we have observed 201 CME events and ...

The visual complexity of coronal mass ejections follows the solar cycle [PDF]
Space Weather, 2020 Abstract The Heliospheric Imagers on board National Aeronautics and Space Administration (NASA)'s twin STEREO spacecraft show that coronal mass ejections (CMEs) can be visually complex structures. To explore this complexity, we created a citizen science project with the U.K.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Experimental Physiology, EarlyView.Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Relationship of Coronal Mass Ejection Events with Solar Flares and coronal Holes [PDF]
Symposium - International Astronomical Union, 1990 We present an analysis of the relationship between coronal mass ejection (CME) events with solar flares and coronal holes. Out of 79 CME events whose location and span are known, 10 CME event circles contain solar flares. On the other hand out of 71 CME events (selected for the study with coronal holes) 40 CME event circles contain coronal holes.

Rotation of a Stealth CME on 2012 October 5 Observed in the Inner Heliosphere
The Astrophysical Journal, 2023 Coronal mass ejections (CMEs) are subject to changes in their direction of propagation, tilt, and other properties. This is because CMEs interact with the ambient solar wind and other large-scale magnetic field structures.

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract Mercury's proximity to the Sun results in the lowest average Alfvénic Mach number in the upstream solar wind compared to any other planet. Under extreme conditions, the upstream Alfvén speed can exceed the solar wind speed, resulting in a sub‐Alfvénic interaction in which standing Alfvén wings form.
