Analysis of a spatially deconvolved solar pore

Ichimoto, K.; Suematsu, Y.; Katsukawa, Y. +3 more

Solar pores are active regions with large magnetic field strengths and apparent simple magnetic configurations. Their properties resemble the ones found for the sunspot umbra although pores do not show penumbra. Therefore, solar pores present themselves as an intriguing phenomenon that is not completely understood. We examine in this work a solar …

Analysis of spatially deconvolved polar faculae

Suematsu, Y.; Shimizu, T.; Ruiz Cobo, B. +2 more

Polar faculae are bright features that can be detected in solar limb observations and they are related to magnetic field concentrations. Although there are a large number of works studying them, some questions about their nature as their magnetic properties at different heights are still open. Thus, we aim to improve the understanding of solar pol…

Analysis of horizontal flows in the solar granulation

Suematsu, Y.; Shimizu, T.; Quintero Noda, C.

Solar limb observations sometimes reveal the presence of a satellite lobe in the blue wing of the Stokes I profile from pixels belonging to granules. The presence of this satellite lobe has been associated in the past to strong line-of-sight gradients and, as the line-of-sight component is almost parallel to the solar surface, to horizontal granul…

Fine structures at pore boundary

Bharti, L.; Quintero Noda, C.; Joshi, C. +2 more

We present high resolution observations of fine structures at pore boundaries. The inner part of granules towards umbra show dark striations which evolve into a filamentary structure with dark core and `Y' shape at the head of the filaments. These filaments migrate into the umbra similar to penumbral filaments. These filaments show higher temperat…
