The net e ect of the small scale magnetic field on the Sun’s (bolometric) brightness is studied with realistic 3D MHD simulations. The direct e ect of brightening within the magnetic field itself is consistent with measurements in high-resolution observations. The high ‘photometric accuracy’ of the simulations, however, reveal compensating brightness e ects that are hard to detect observationally. The influence of magnetic concentrations on the surrounding nonmagnetic convective flows (a…

Simulation of the small-scale magnetism in main-sequence stellar atmospheres

Context. Observations of the Sun tell us that its granular and subgranular small-scale magnetism has significant consequences for global quantities such as the total solar irradiance or convective

Interaction of convective plasma and small-scale magnetic fields in the lower solar atmosphere

In the following short review we will outline some of the possible interaction processes of lower solar atmospheric plasma with the embedded small-scale solar magnetic fields. After introducing the

Small-scale dynamos on the solar surface: dependence on magnetic Prandtl number

The question of possible small-scale dynamo action in the surface layers of the Sun is revisited with realistic 3D MHD simulations. As in other MHD problems, dynamo action is found to be a sensitive

PHOTOMETRIC TRENDS IN THE VISIBLE SOLAR CONTINUUM AND THEIR SENSITIVITY TO THE CENTER-TO-LIMB PROFILE

Solar irradiance variations over solar rotational timescales are largely determined by the passage of magnetic structures across the visible solar disk. Variations on solar cycle timescales are

TURBULENT MAGNETIC FIELDS IN THE QUIET SUN: IMPLICATIONS OF HINODE OBSERVATIONS AND SMALL-SCALE DYNAMO SIMULATIONS

Using turbulent MHD simulations (magnetic Reynolds numbers up to ≈8000) and Hinode observations, we study effects of turbulence on measuring the solar magnetic field outside active regions. First,

Intensity contrast from MHD simulations and HINODE observations

Context. Changes in the solar surface area, which is covered by small-scale magnetic elements, are thought to cause long-term changes in the solar spectral irradiance, which are important for

Multi-channel magnetograph observations

Simultaneous observations of photospheric magnetic fields, Caii K emission, the ‘photospheric network’ and continuum faculae show that these four quantities are correlated in a complicated manner.

Radiative properties of magnetic elements II. Center to limb variation of the appearance of photospheric faculae

For the understanding of more complex numerical simulation results, a basic facular model is created consisting of a magnetic flux sheet embedded in a plane parallel atmosphere. The atmosphere within

Do Photospheric Brightness Structures Outside Magnetic Flux Tubes Contribute to Solar Luminosity Variation?

Variations in total solar irradiance (TSI) correlate well with changes in projected area of photospheric magnetic flux tubes associated with dark sunspots and bright faculae in active regions and

Heating and activity of the solar corona: 1. Boundary shearing of an initially homogeneous magnetic field

To contribute to the understanding of heating and dynamic activity in boundary‐driven, low‐beta plasmas such as the solar corona, we investigate how an initially homogeneous magnetic field responds

Time sequences of interleaved observations of the continuum intensity, longitudinal magnetic field, vertical velocity in the midphotosphere, and the line-center intensity in Ni I 6768 A were obtained

Context. To deepen our understanding of the role of small-scale magnetic fields in active regions (ARs) and in the quiet Sun (QS) on the solar irradiance, it is fundamental to investigate the

Abstract.Electromagnetic radiation from the Sun is Earth’s primary energy source. Space-based radiometric measurements in the past two decades have begun to establish the nature, magnitude and
