TL;DR: In this paper, the authors study the three-dimensional configuration of a sunspot and its light bridge during one of the last stages of its decay, and they find that the photospheric light bridge is dominated by gas pressure (high-β ), as opposed to the surrounding umbra, where the magnetic pressure is higher.

Convective Nature of Sunspot Penumbral Filaments: Discovery of Downflows in the Deep Photosphere
TL;DR: In this paper, the velocity structure of penumbral filaments in the deep photosphere was studied to obtain direct evidence for the convective nature of sunspot penumbrae.

Effect of polarimetric noise on the estimation of twist and magnetic energy of force-free fields
TL;DR: In this paper, the authors investigated the effect of polarimetric noise on the calculation of global {alpha} value and magnetic energy of an analytical bipole using the force-free field approximation.

The cause of spatial structure in solar He i 1083 nm multiplet images
TL;DR: In this article, the effect of the three-dimensional temperature and density structure in the solar atmosphere on the formation of the He i 1083 nm line is investigated, and the authors compare their results to observations using SST, IRIS and SDO/AIA data using a snapshot from a 3D radiation-MHD simulation computed with the Bifrost code.
Observations of Ellerman bomb emission features in He I D3 and He I 10830 {\AA}

TL;DR: In this article, the authors studied the signature of EBs in neutral helium triplet lines and concluded that the EBs must have high temperatures to exhibit emission signals in the lines.
