Solar System chaos and the Paleocene–Eocene boundary age constrained by geology and astronomy [PDF]
Science, 2019 Filling a dating hole The periodic nature of Earth's orbit around the Sun produces cycles of insolation reflected in climate records. Conversely, these climate records can be used to infer changes in the dynamics of the Solar System, which is inherently ...

Dynamical Evolution of the Early Solar System [PDF]
Annual Review of Astronomy and Astrophysics, 2018 Several properties of the Solar System, including the wide radial spacing of the giant planets, can be explained if planets radially migrated by exchanging orbital energy and momentum with outer disk planetesimals. Neptune's planetesimal-driven migration,

Organics in the solar system [PDF]
Research in Astronomy and Astrophysics, 2019 Complex organics are now commonly found in meteorites, comets, asteroids, planetary satellites, and interplanetary dust particles. The chemical composition and possible origin of these organics are presented. Specifically, we discuss the possible link between Solar System organics and the complex organics synthesized during the late stages of stellar ...

Full-disc Ca ii K observations—A window to past solar magnetism
Frontiers in Astronomy and Space Sciences, 2022 Full-disc observations of the Sun in the Ca ii K line provide one of the longest collections of solar data. First such observations were made in 1892 and since then various sites around the world have carried out regular observations, with Kodaikanal ...
