The late accretion and erosion of Vesta’s crust recorded by eucrites and diogenites as an astrochemical window into the formation of Jupiter and the early evolution of the Solar System [PDF]

open access: yesIcarus, 2018
For decades the limited thickness of Vesta's basaltic crust, revealed by the link between the asteroid and the howardite-eucrite-diogenite family of meteorites, and its survival to collisional erosion offered an important constraint for the study of the early evolution of the Solar System.

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 ...

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 PHYSICAL MEANING OF THE TITIUS-BODE FORMULA

open access: yesOdessa Astronomical Publications, 2016
It is proposed an special hypothesis of the formation of symmetric objects in space with the help of the interference of standing waves which act in the process of evolution of the primordial gas-dust cloud including the formation of the Solar system ...

The formation of the solar system

open access: yes, 2015
The solar system started to form about 4.56 Gyr ago and despite the long intervening time span, there still exist several clues about its formation. The three major sources for this information are meteorites, the present solar system structure and the ...

Research progress on internal characteristics of asteroids and comets: implications of Tianwen-2 radar observations

open access: yesEarth and Planetary Physics
Asteroids and comets, which have long been of interest to astronomers, are important components of the solar system. They contain rich primitive information about the early solar system, which provide a unique pathway for studying the formation and ...

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

Planetary Science Goals for the Spitzer Warm Era [PDF]

open access: yes, 2007
The overarching goal of planetary astronomy is to deduce how the present collection of objects found in our Solar System were formed from the original material present in the proto-solar nebula.

A perspective from extinct radionuclides on a Young Stellar Object: The Sun and its accretion disk

open access: yes, 2011
Meteorites, which are remnants of solar system formation, provide a direct glimpse into the dynamics and evolution of a young stellar object (YSO), namely our Sun.

Chondrule formation and evolution of the early solar system

open access: yesJournal of Mineralogical and Petrological Sciences, 2006
Chondrules are millimeter to sub-millimeter size silicate spherules that formed during localized and transient high-temperature events in the early solar system. Although it is not yet understood how chondrules formed, recent studies have provided important clues in understanding the physical conditions of chondrule formation.
