Interchange reconnection has been proposed as a mechanism for the generation of the slow solar wind, and a key contributor to determining its characteristic qualities. We study the implications of interchange reconnection for the structure of the plasma and field in the heliosphere in the context of the "S-Web" model. We show that photospheric driving at supergranular scales leads to a...
Understanding processes in the quiet Sun is crucial for understanding the Sun in general. The overarching goal of our study is to quantify the energy output of the quiet Sun, which can be expressed in terms of the Poynting flux. To compute this quantity, one can use Maxwell's equations, provided the full orientation of magnetic, electric, and velocity fields are available. All of those can be...
The confluence of the data from the Murchison Widefield Array and an imaging pipeline tailored for spectroscopic snapshot images of the Sun at low radio frequencies have led to enormous improvements in the imaging quality of the Sun. These developments have lowered the detection threshold for nonthermal emissions by up to two orders of magnitude as compared to earlier studies, and enabled our...
The third flight of the Sunrise observatory carries the new Sunrise UV Spectropolarimeter and Imager (SUSI) which will cover the spectral range from 310 nm to 410 nm. In this region, the number density of spectral lines is at least four times larger than in the visible/infrared part of the spectrum, including a significant number of chromospheric lines. To extract accurate physical parameters...
Numerical and observational evidences both support that wave propagation and dissipation may be an important mechanism that contributes to the heating of the solar chromosphere. For instance, acoustic waves and the resulting shock waves in the gravitationally stratified solar atmosphere, may provide at least part of the energy to compensate the radiative energy losses in the chromosphere....
Thermal non-equilibrium (TNE) produces several observables that can be used to constrain the spatial and temporal distribution of coronal heating. Its manifestations include prominence formation, coronal rain, and long-period intensity pulsations in coronal loops. The recent observation of abundant periodic coronal rain associated with intensity pulsations by Auchère et al. allows to unify...
