Solar–Stellar Connection: X-Ray Flares to Energetic (E > 10 MeV) Particle Events

The Astrophysical Journal, 2023
Energetic particle environments are an important factor for the viability of life on exoplanets surrounding flare stars. In the heliosphere, large gradual solar energetic ( E > 10 MeV) particle (SEP) events are produced by shocks from fast coronal mass ...

Solar evolution and extrema: current state of understanding of long-term solar variability and its planetary impacts

Progress in Earth and Planetary Science, 2021
The activity of stars such as the Sun varies over timescales ranging from the very short to the very long—stellar and planetary evolutionary timescales.

Stellar magnetic activity – Star-Planet Interactions

EPJ Web of Conferences, 2015
Stellar magnetic activity is an important factor in the formation and evolution of exoplanets. Magnetic phenomena like stellar flares, coronal mass ejections, and high-energy emission affect the exoplanetary atmosphere and its mass loss over time.

Power-law Distribution of Solar Cycle–modulated Coronal Jets

The Astrophysical Journal Supplement Series, 2023
Power-law distributions have been studied as a significant characteristic of nonlinear dissipative systems. Since discovering the power-law distribution of solar flares that was later extended to nanoflares and stellar flares, it has been widely accepted

Looking for the elusive stellar coronal mass ejections. How can LOFAR help?

, 2022
Abstract: Coronal mass ejections (CMEs) are the most explosive manifestations of stellar magnetic activity. In the solar case, CMEs and flares are associated with each other and this association increases with increasing flaring energy, reaching 100% for high energies. But does this hold true for other stars?

Free‐Breathing 3D Whole Heart and Aorta Cine MRI Without Contrast Agent—Comparison to Clinical Standard

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background The demand for cardiac MRI is increasing with the growing burden of cardiovascular disease. However, conventional protocols require sequential acquisitions for multi‐breath‐hold 2D cine and 3D MR angiography (MRA), which is time‐consuming.

Terendak Military Cemetery: Bodies, Burials, and ‘Operation Bring Them Home'

Australian Journal of Politics &History, EarlyView.
Terendak Military Cemetery occupies an unusual position in the history of Australian war cemeteries. Initially established to service the needs of the community at Terendak Garrison—the operational base for Commonwealth forces in Malaya during the early years of the Cold War—it became the official overseas burial site of Australian dead during the ...

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 ...
