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.

TL;DR: In this paper, the authors study the three dimensional configuration of a sunspot and in particular its light bridge during one of the last stages of its decay, and conclude that it develops because of two highly magnetized regions which come closer during the sunspot evolution.

TL;DR: In this paper, the magnetic line ratio analysis of the infrared spectropolarimetric data at a spatial resolution of ≈ 0.4 was performed with the GREGOR telescope.
