The Decay of Two Adjacent Sunspots Associated with Moving Magnetic Features

The Astrophysical Journal
The relationship between the decay of sunspots and moving magnetic features (MMFs) plays an important role in understanding the evolution of active regions.

Statistical Comparison between Pores and Sunspots during the Time Interval 2010–2023

The Astrophysical Journal
To reveal the physical properties of pores and sunspots varying with solar cycle, we carried out a statistical comparison among pores, transitional sunspots, and mature sunspots using Solar Dynamics Observatory/Helioseismic and Magnetic Imager from 2010 ...

Simultaneous Spectropolarimetric Observations in the Hα and Ca ii 8662 Å Lines of an Active Region

The Astrophysical Journal
We present spectropolarimetric observations of an active region recorded simultaneously in the H α and the Ca ii 8662 Å lines. The sunspot exhibits multiple structures, including a light bridge and a region where the Ca ii 8662 Å line core is in emission.

Can Instrumental Effects Obscure the True Photospheric Wave Spectrum?

The Astrophysical Journal
Optical aberrations and instrument resolution can affect the observed morphological properties of features in the solar atmosphere. However, little work has been done to study the effects of spatial resolution on the dynamical processes occurring in the ...
