The Sun
Our Sun is the only star whose surface we can study in detail due to its proximity. Through space missions are also in situ measurements possible.

The Sun: Dark and Cold
AbstractThis paper makes an attempt to describe the ideas about the Sun that dominated Europe in the 17th–19th centuries.

Main Characteristics of the Sun
The Sun is the central body of our Solar System. It is a hot rotating gas sphere with a radius of RS = 6.96 × 1010 cm and a mass of...

A Stellar View of the Sun
This invited memoir looks back on my scientific career that straddles the solar and stellar branches of astrophysics, with sprinklings of historical...

Propagation of coronal mass ejections from the Sun to the Earth
Coronal mass ejections (CMEs), as they can inject a large amounts of mass and magnetic flux into the interplanetary space, are the primary source of...

On the Question of Localizing the Birthplaces of Coronal Mass Ejections on the Sun
AbstractThe localization of zones of occurrence of coronal mass ejections (CME) on the Sun in the period from November 2006 to February 2007 was...

The Sun and Its Restless Magnetic Field
The permanently changing magnetic field of the Sun is the ultimate driver of the various effects refered to as space weather. This chapter gives an...

GAIA Arguments for and against a Hypothetical Sun Companion
AbstractThe hypothesis that the Sun is a component of a binary star system has been around for about a hundred years. Assumptions about the nature of...

Observations of cross scale energy transfer in the inner heliosphere by Parker Solar Probe
The solar wind, a continuous flow of plasma from the sun, not only shapes the near Earth space environment but also serves as a natural laboratory to...

Is there a black hole in the center of the Sun?
There is probably not a black hole in the center of the Sun. Despite this detail, our goal in this work to convince the reader that this question is...

Theoretical and Observed Signs of Excitation of Small-Scale Magnetic Fluctuations in the Depth of the Sun
AbstractAn actual problem today is the search for observed evidence of the existence of deep small-scale magnetic fields of the Sun. In this regard,...

Magnetic Properties of Source Regions of CMEs and DH Type II Radio Bursts
The Sun is a dynamic star that exhibits various phenomena, including solar flares, coronal mass ejections (CMEs), and Type II radio bursts. CMEs are...

Surface Flux Transport on the Sun
We review the surface flux transport model for the evolution of magnetic flux patterns on the Sun’s surface. Our underlying motivation is to...

The Sun: Methodology, Theory, Practice
AbstractThe paper provides a general overview of the current state of solar research.

Getting To Know The Sun
Since time immemorial, people have stared in wonder at the sky. In addition to the familiar, twinkling stars, observers noted seven objects that...

Direct detection of ultralight dark matter bound to the Sun with space quantum sensors
Recent advances in quantum sensors, including atomic clocks, enable searches for a broad range of dark matter candidates. The question of the dark...

Long-Lived Recurrent Fluxes of Energetic Ions from Coronal Holes on the Sun
AbstractResults are presented from studying the relative abundances and energy spectra of 4 He, C, O, and Fe suprathermal ions in particle fluxes...

Spatially resolved imaging of the inner Fomalhaut disk using JWST/MIRI
Planetary debris disks around other stars are analogous to the asteroid and Kuiper belts in the Solar System. Their structure reveals the...
