Solar Coronal Mass Ejections [PDF]
Symposium - International Astronomical Union, 1990 In addition to the more or less steady solar wind, the Sun also ejects mass in highly time dependent events taking place in the corona once every few days at solar activity minimum and as often as three times a day at solar activity maximum (Hundhausen 1988, Low 1986).

Commission 10: Solar Activity [PDF]
, 2007 Commission 10 aims at the study of various forms of solar activity, including networks, plages, pores, spots, fibrils, surges, jets, filaments/prominences, coronal loops, flares, coronal mass ejections (CMEs), solar cycle, microflares, nanoflares ...

Stellar winds, dead zones, and coronal mass ejections [PDF]
, 1999 Axisymmetric stellar wind solutions are presented, obtained by numerically solving the ideal magnetohydrodynamic (MHD) equations. Stationary solutions are critically analysed using the knowledge of the flux functions.

The evolution of our understanding of coronal mass ejections
Frontiers in Astronomy and Space Sciences, 2023 The unexpected observation of a sudden expulsion of mass through the solar corona in 1971 opened up a new field of interest in solar and stellar physics.

Coronal Mass Ejections and Coronal Structures [PDF]
, 1989 The coronal portion of the solar atmosphere consists of a wide variety of structures which exhibit a similarly wide variety of dynamical processes and kinds of activity. The launch of the SMM presented an opportunity to study the low and intermediate corona from space with multiple instruments for protracted periods of time.

A numerical study of two interacting coronal mass ejections [PDF]
Annales Geophysicae, 2004 The interaction in the solar wind between two coronal mass ejections (CMEs) is investigated using numerical simulations. We show that the nature of the interaction depends on whether the CME magnetic structures interact, but in all cases the result is

Coronal mass ejections from the same active region cluster: Two different perspectives [PDF]
, 2015 The cluster formed by active regions (ARs) NOAA 11121 and 11123, approximately located on the solar central meridian on 11 November 2010, is of great scientific interest.
