Estimating Coronal Mass Ejection Mass and Kinetic Energy by Fusion of Multiple Deep-learning Models
The Astrophysical Journal Letters, 2023 Coronal mass ejections (CMEs) are massive solar eruptions, which have a significant impact on Earth. In this paper, we propose a new method, called DeepCME, to estimate two properties of CMEs, namely, CME mass and kinetic energy.

, 2010 On 5 April 2010 an interplanetary (IP) shock was detected by the Wind spacecraft ahead of Earth, followed by a fast (average speed 650 km/s) IP coronal mass ejection (ICME).

A synoptic view of solar transient evolution in the inner heliosphere using the Heliospheric Imagers on STEREO [PDF]
, 2009 By exploiting data from the STEREO/heliospheric imagers (HI) we extend a well-established technique developed for coronal analysis by producing time-elongation plots that reveal the nature of solar transient activity over a far more extensive region of ...

The Astrophysical Journal, 2007 Observations of the low solar corona in the extreme ultraviolet and in soft X-rays evidence a close relationship of coronal dimmings and coronal mass ejections (CMEs). Dimmings are usually interpreted as places of plasma evacuation during a CME. We characterize a CME by the apparent angular extent of associated dimmings above the solar limb and define ...

Validation of Intravoxel Incoherent Motion MRI Using Perfused Explanted Human Livers
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose Evaluate the feasibility of using perfused explanted human livers for validating intravoxel incoherent motion (IVIM). Methods Eight (n = 8) explanted livers from deceased donors were obtained. The portal vein and hepatic artery of each explanted liver were connected to a perfusion system.

The Astrophysical Journal Supplement SeriesCoronal mass ejections (CMEs) are among the most energetic phenomena in our solar system, with significant implications for space weather. Understanding their early dynamics remains challenging due to observational limitations in the low corona.

Dynamic disappearance of prominences and their geoeffectiveness [PDF]
Geofísica Internacional, 2008 We study 14 cases of dynamic “disparition brusque” (DBd), the sudden disappearance of quiescent filaments/prominences, during two solar minima: 1985-1986 and 1994.

A Type II Radio Burst Driven by a Blowout Jet on the Sun
The Astrophysical Journal, 2023 Type II radio bursts are often associated with coronal shocks that are typically driven by coronal mass ejections (CMEs) from the Sun. Here we conduct a case study of a type II radio burst that is associated with a C4.5-class flare and a blowout jet, but

COMPOSITION OF CORONAL MASS EJECTIONS [PDF]
The Astrophysical Journal, 2016 ABSTRACT We analyze the physical origin of plasmas that are ejected from the solar corona. To address this issue, we perform a comprehensive analysis of the elemental composition of interplanetary coronal mass ejections (ICMEs) using recently released elemental composition data for Fe, Mg, Si, S, C, N, Ne, and He as compared to O and H ...

A Coronal Hole's Effects on CME Shock Morphology in the Inner Heliosphere
, 2012 We use STEREO imagery to study the morphology of a shock driven by a fast coronal mass ejection (CME) launched from the Sun on 2011 March 7. The source region of the CME is located just to the east of a coronal hole. The CME ejecta is deflected away from
