How many CMEs have flux ropes? Deciphering the signatures of shocks, flux ropes, and prominences in coronagraph observations of CMEs

A Vourlidas, BJ Lynch, RA Howard, Y Li - Solar Physics, 2013 - Springer
We intend to provide a comprehensive answer to the question on whether all Coronal Mass
Ejections (CMEs) have flux rope structure. To achieve this, we present a synthesis of the …

Physical processes in magnetically driven flares on the sun, stars, and young stellar objects

AO Benz, M Güdel - Annual Review of Astronomy and …, 2010 - annualreviews.org
The first flare on the Sun was observed exactly 150 years ago. During most of the long
history, only secondary effects have been noticed, so flares remained a riddle. Now the …

Ultra-wideband detection of 22 coherent radio bursts on M dwarfs

J Villadsen, G Hallinan - The Astrophysical Journal, 2019 - iopscience.iop.org
Coherent radio bursts detected from M dwarfs have some analogy with solar radio bursts but
reach orders of magnitude higher luminosities. These events trace particle acceleration …

X Cheng, Y Guo, MD Ding - Science China Earth Sciences, 2017 - Springer
Coronal mass ejections (CMEs) and solar flares are the large-scale and most energetic
eruptive phenomena in our solar system and able to release a large quantity of plasma and …

Extreme kinematics of the 2017 September 10 solar eruption and the spectral characteristics of the associated energetic particles

N Gopalswamy, S Yashiro, P Mäkelä… - The Astrophysical …, 2018 - iopscience.iop.org
We report on the 2017 September 10 ground-level enhancement (GLE) event associated

History and development of coronal mass ejections as a key player in solar terrestrial relationship

N Gopalswamy - Geoscience Letters, 2016 - Springer
Coronal mass ejections (CMEs) are relatively a recently discovered phenomenon—in 1971,
some 15 years into the Space Era. It took another two decades to realize that CMEs are the …

The Sun and space weather

N Gopalswamy - Atmosphere, 2022 - mdpi.com
The explosion of space weather research since the early 1990s has been partly fueled by
the unprecedented, uniform, and extended observations of solar disturbances from space …

Type II radio bursts and their association with coronal mass ejections in solar cycles 23 and 24

A Kumari, DE Morosan, EKJ Kilpua, F Daei - Astronomy & Astrophysics, 2023 - aanda.org
Context. Meter-wavelength type II solar radio bursts are thought to be the signatures of
shock-accelerated electrons in the corona. Studying these bursts can give information about …
