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.

Solar Physics with the Square Kilometre Array [PDF]

, 2018
The Square Kilometre Array (SKA) will be the largest radio telescope ever built, aiming to provide collecting area larger than 1 km$^2$. The SKA will have two independent instruments, SKA-LOW comprising of dipoles organized as aperture arrays in ...

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

Solar Wind and its Evolution [PDF]

, 2011
By using our previous results of magnetohydrodynamical simulations for the solar wind from open flux tubes, I discuss how the solar wind in the past is different from the current solar wind.

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.

Hot Jupiters and the evolution of stellar angular momentum [PDF]

, 2009
Giant planets orbiting main-sequence stars closer than 0.1 AU are called hot Jupiters. They interact with their stars affecting their angular momentum. Recent observations provide suggestive evidence of excess angular momentum in stars with hot Jupiters ...

Fractal Reconnection in Solar and Stellar Environments

, 2016
Recent space based observations of the Sun revealed that magnetic reconnection is ubiquitous in the solar atmosphere, ranging from small scale reconnection (observed as nanoflares) to large scale one (observed as long duration flares or giant arcades ...

The Solar Particle Acceleration Radiation and Kinetics (SPARK) Mission Concept

Aerospace, 2023
Particle acceleration is a fundamental process arising in many astrophysical objects, including active galactic nuclei, black holes, neutron stars, gamma-ray bursts, accretion disks, solar and stellar coronae, and planetary magnetospheres.

Eruptions from solar ephemeral regions as an extension of the size distribution of coronal mass ejections

, 2009
Observations of the quiet solar corona in the 171A (~1MK) passband of the Transition Region and Coronal Explorer (TRACE) often show disruptions of the coronal part of small-scale ephemeral bipolar regions that resemble the phenomena associated with ...

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 ...
