Rigorous Use of Light-curve Inversion and Stellar Occultation Techniques for Deriving a Scaled Three-dimensional Shape for the Jupiter Trojan (911) Agamemnon

The Astrophysical Journal
This work presents a methodology for determining the size, three-dimensional shape, and rotational parameters of small solar system objects, with rigorous uncertainty determination, using stellar occultations, rotational and phase-angle light curves ...

Snapshots of an Evolving Solar Nebula Recorded in Nucleosynthetic Sr and Ba Signatures of Early Condensates

The Astrophysical Journal Letters
The discovery of extreme strontium isotope anomalies ( μ ^84 Sr) in refractory leachates from Allende fine-grained calcium-aluminum-rich inclusions (CAIs) is at odds with long-standing predictions regarding the homogenization of presolar components in ...

Geoelectrochemistry-driven alteration of amino acids to derivative organics in carbonaceous chondrite parent bodies

Nature Communications, 2022
Researchers at Earth-Life Science Institute (ELSI) discovered a chemical process that can explain the very low amino acid abundances in aqueously altered carbonaceous chondrites, deepening our understanding on the Solar System chemical evolution.

Rapid protoplanet formation in the outer Solar System recorded in a dunite from the carbonaceous chondrite reservoir

Communications Earth & Environment
Constraining the timing of accretion, differentiation, and breakup of early-formed protoplanets helps to unravel the Solar System’s evolution. The recent discovery of the oldest crustal material, Erg Chech 002, has provided important constraints on the ...

Satellites and Small Bodies With ALMA: Insights Into Solar System Formation and Evolution

AGU Advances
Our understanding of the formation and evolution of planetary systems has made major advances in the past decade. This progress has been driven in large part by the Atacama Large Millimeter/submillimeter Array (ALMA), which has given us an unprecedented ...

Hypothesis about Enrichment of Solar System

Physics, 2020
Despite significant progress in the understanding of galactic nucleosynthesis and its influence on the solar system neighborhood, challenges remain in the understanding of enrichment of the solar system itself.

Oxygen Isotope Constraints on the Importance of Photochemical Processing in Protoplanetary Disks

The Astronomical Journal
Observations have revealed evidence of photochemical processing in protoplanetary disks. This processing occurs in the photon-dominated layer, the optically thin regions of the disk high above the disk midplane. It remains unclear, however, how much this

Passing Stars as an Important Driver of Paleoclimate and the Solar System’s Orbital Evolution

The Astrophysical Journal Letters
Reconstructions of the paleoclimate indicate that ancient climatic fluctuations on Earth are often correlated with variations in its orbital elements. However, the chaos inherent in the solar system’s orbital evolution prevents numerical simulations from

Long Term Evolution of the Solar System [PDF]

Symposium - International Astronomical Union, 1992
The mapping method of Wisdom (1982) has been generalized to encompass all n-body problems with a dominant central mass (Wisdom and Holman, 1991). The new mapping method is presented as well as a number of initial applications. These include billion year integrations of the outer planets, a number of 100 million year integrations of the whole solar ...
