Is the Sun a Magnet?
DO Gough
Jul 05, 2017
It has been argued (Gough and McIntyre in Nature394, 755, 1998) that the only way for the radiative interior of the Sun to be rotating uniformly in the face of the differentially rotating convection zone is for it to be pervaded...

This article aims to alert the medical community and public health authorities to accumulating evidence on health benefits from sun exposure, which suggests that insufficient sun exposure is a significant public health problem....
Solar Radiation Prediction Model Based on Spatial Attention Mechanisms and Sun Position Feature Maps
This study introduces a novel method for predicting solar radiation by focusing on the sun's position and cloud conditions in the sky. The proposed approach utilizes sun position feature maps and spatial attention mechanisms to...

Unsigned Magnetic Flux as a Proxy for Radial-velocity Variations in Sun-like Stars
RD Haywood, TW Milbourne, SH Saar, A Mortier, D Phillips, D Charbonneau, AC Cameron, HM Cegla, N Meunier, MLP Iii
Aug 08, 2022
We estimate disc-averaged RV variations of the Sun over the last magnetic
cycle, from the single Fe I line observed by SDO/HMI, using a physical model
for rotationally modulated magnetic activity that was previously...
