The magnetic fields, activity and hidden companions of solar-type stars [PDF]
, 2023 The magnetic fields of the Sun and other solar-type stars manifest in a range of observable surface phenomena that provide insight into the magnetic dynamos operating within, but also hamper the detection of exoplanets.

Deciphering solar magnetic activity: on grand minima in solar activity [PDF]
Frontiers in Astronomy and Space Sciences, 2015 The Sun provides the energy necessary to sustain our existence. While the Sun provides for us, it is also capable of taking away. The weather and climatic scales of solar evolution and the Sun-Earth connection are not well understood. There has been tremendous progress in the century since the discovery of solar magnetism - magnetism that ultimately ...

NANOFLARE ACTIVITY IN THE SOLAR CHROMOSPHERE [PDF]
The Astrophysical Journal, 2014 We use ground-based images of high spatial and temporal resolution to search for evidence of nanoflare activity in the solar chromosphere. Through close examination of more than 10^9 pixels in the immediate vicinity of an active region, we show that the distributions of observed intensity fluctuations have subtle asymmetries.

Heartbeat of the sun from principal component analysis and prediction of solar activity on a millenium timescale [PDF]
, 2015 We derive two principal components (PCs) of temporal magnetic field variations over the solar cycles 21-24 from full disk magnetograms covering about 39% of data variance, with σ = 0.67. These PCs are attributed to two main magnetic waves travelling from
