The outer solar system

open access: yesEPJ Web of Conferences, 2009
The outer solar system extends beyond a heliocentric distance of 5 AU. It contains the giant planets and their systems (rings and satellites), the Kuiper belt, the comets (except those which approach episodically the inner solar system) and, at its outer

The Heliospheric Magnetic Field

open access: yesLiving Reviews in Solar Physics, 2013
The heliospheric magnetic field (HMF) is the extension of the coronal magnetic field carried out into the solar system by the solar wind. It is the means by which the Sun interacts with planetary magnetospheres and channels charged particles propagating ...

On the Analytical Models of Protoplanetary Formation in Extrasolar Systems

open access: yesSpace: Science & Technology, 2022
In this work, we consider a statistical theory for a cosmogonical body formation (so-called spheroidal body) to develop the analytical models of protoplanetary formation in extrasolar systems. Within the framework of this theory, the models and evolution

Probing Massive Star Nucleosynthesis with Data on Metal-Poor Stars and the Solar System [PDF]

open access: yesEPJ Web of Conferences, 2022
Metal-poor stars were formed during the early epochs when only massive stars had time to evolve and contribute to the chemical enrichment. Low-mass metal-poor stars survive until the present and provide fossil records of the nucleosynthesis of early ...
