The goal of the SunPy project is to facilitate and promote the use and development of
community-led, free, and open source data analysis software for solar physics based on the …

While the photospheric magnetic field of our Sun is routinely measured, its extent into the
upper atmosphere is typically not accessible by direct observations. Here we present an …

Nonlinear force-free extrapolations are a common approach to estimate the 3D topology of
coronal magnetic fields based on photospheric vector magnetograms. The force-free …

We present a new data product, called Space-Weather MDI Active Region Patches
(SMARPs), derived from maps of the solar surface magnetic field taken by the Michelson …

Context. Stellar variability strongly impacts the search for low-mass exoplanets with radial
velocity techniques. Two types of planet-free time series can be used to quantify this impact …

The Sun is one of the most luminous γ-ray sources in the sky and continues to challenge our
understanding of its high-energy emission mechanisms. This study provides an in-depth …

Abstract On 2024 May 10–11, the strongest geomagnetic storm since 2003 November
occurred, with a peak Dst index of− 412 nT. The storm was caused by NOAA active region …

Superresolution (SR) aims to increase the resolution of images by recovering detail.
Compared to standard interpolation, deep learning-based approaches learn features and …

The Sun, our nearest star, is a local laboratory for studying universal physical processes.
Solar physics as a discipline includes studying the Sun both as a star and as the primary …

Recent observational studies identified a foreground stellar sub-structure traced by red
clump (RC) stars (∼ 12 kpc in front of the main body) in the eastern regions of the Small …
