On Flux Rope Stability and Atmospheric Stratification in Models of Coronal Mass Ejections Triggered by Flux Emergence [PDF]

, 2014
Flux emergence is widely recognized to play an important role in the initiation of coronal mass ejections. The Chen-Shibata (2000) model, which addresses the connection between emerging flux and flux rope eruptions, can be implemented numerically to ...

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 ...

Solar and Stellar Coronal Mass Ejections - a review of the Cool Stars 21 splinter session

, 2023
Coronal mass ejections (CMEs) are the most energetic phenomena related to magnetic activity and, by impacting the interplanetary space, they can be the source of severe planetary disturbances. Solar CMEs and their sources, such as flares and filament/prominence eruptions, have been intensively observed and studied over decades.

The state of knowledge on four families of Syngnathoidei fishes (Teleostei: Syngnathiformes): Aulostomidae, Centriscidae, Fistulariidae and Solenostomidae

Journal of Fish Biology, EarlyView.
Abstract Knowledge on the ecology and life‐history traits of coastal marine species is vital to inform their conservation and management, especially as their coastal habitats come under increasing threats. However, such data have never been collated for four of the five families in the suborder Syngnathoidei—the close relatives of the better‐studied ...

Two Energy Release Processes for CMEs: MHD Catastrophe and Magnetic Reconnection

, 2007
It remains an open question how magnetic energy is rapidly released in the solar corona so as to create solar explosions such as solar flares and coronal mass ejections (CMEs).

Ultra-Wideband Detection of 22 Coherent Radio Bursts on M Dwarfs [PDF]

, 2018
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, powered by magnetic reconnection, shock fronts (such as formed by coronal
