Quiet Sun magnetic fields: an observational view

open access: yesLiving Reviews in Solar Physics, 2019
The quiet Sun is the region of the solar surface outside of sunspots, pores, and plages. In continuum intensity it appears dominated by granular convection.

Small-scale swirl events in the quiet Sun chromosphere [PDF]

open access: yesAstronomy and Astrophysics, 2009
Recent progress in instrumentation enables solar observations with high resolution simultaneously in the spatial, temporal, and spectral domains. We use such high-resolution observations to study small-scale structures and dynamics in the chromosphere of

Young children's perspectives of time: New directions for co‐constructing understandings of quality in ECEC

open access: yesBritish Educational Research Journal, EarlyView., 2023
Abstract Children's relationship with time in preschools is an under‐researched area. Young children rarely know how to measure time using a clock, but their experiences of time may contribute to understanding children's well‐being and debates about quality in preschools.

Transport of Cosmic-Ray Electrons from 1 au to the Sun

open access: yesThe Astrophysical Journal, 2023
Gamma rays are produced by cosmic-ray (CR) protons interacting with the particles at the solar photosphere and by CR electrons and positrons (CRes) via inverse Compton scattering of solar photons.

Fleeting Small-scale Surface Magnetic Fields Build the Quiet-Sun Corona

open access: yesThe Astrophysical Journal Letters, 2023
Arch-like loop structures filled with million Kelvin hot plasma form the building blocks of the quiet-Sun corona. Both high-resolution observations and magnetoconvection simulations show the ubiquitous presence of magnetic fields on the solar surface on ...

Substructure of quiet sun bright points [PDF]

open access: yesProceedings of the International Astronomical Union, 2010
AbstractSince photospheric bright points (BPs) were first observed, there has been a question as to how are they structured. Are they just single flux tubes or a bundle of the flux-tubes? Surface photometry of the quiet Sun (QS) has achieved resolution close to 0.1″ with the New Solar Telescope at Big Bear Solar Observatory.

The dynamic chromosphere at millimeter wavelengths

open access: yesFrontiers in Astronomy and Space Sciences, 2022
The chromosphere is one of the most complex and dynamic layers of the solar atmosphere. The dynamic phenomena occur on different spatial and temporal scales, not only in active regions but also in the so-called quiet Sun.

Quiet Sun coronal heating: A statistical model [PDF]

open access: yesAstronomy & Astrophysics, 2002
Recent observations of Krucker & Benz (1998) give strong support to Parker's hypothesis (Parker 1988) that small scale dissipative events make the main contribution to quiet Sun coronal heating. They also showed that these small scale events are associated not only with the magnetic network, but also with the cell interiors (Benz & Krucker ...

Quantifying and containing the curse of high resolution coronal imaging [PDF]

open access: yesAnnales Geophysicae, 2008
Future missions such as Solar Orbiter (SO), InterHelioprobe, or Solar Probe aim at approaching the Sun closer than ever before, with on board some high resolution imagers (HRI) having a subsecond cadence and a pixel area of about (80 km)2 at the Sun ...
