I report results from accurate numerical integrations of Solar System orbits over the past 100Myr with the integrator package HNBody. The simulations used different integrator algorithms, step sizes, initial conditions, and included effects from general relativity, different models of the Moon, the Sun's quadrupole moment, and up to sixteen asteroids. I also probed the potential effect of a hypothetical Planet 9, using one set of possible orbital elements. The most expensive integration… Expand
Solar System chaos and the Paleocene–Eocene boundary age constrained by geology and astronomy
Geologic data and an astronomical solution showing exceptional agreement from ~58 to 53 Ma and a new absolute astrochronology up to 58 Ma are presented and it is shown that the Paleocene–Eocene Thermal Maximum (PETM) onset occurred near a 405-thousand-year eccentricity maximum, suggesting an orbital trigger.

The variation of the Earth's movements (orbital, tilt, and precession) and climate change
Abstract The Earth's orbit and rotational axis change with time due to the gravitational interactions between the Sun, planets, moons, and asteroids of our solar system. These changes haveExpand
An Orbital Window into the Ancient Sun’s Mass
Models of the Sun's long-term evolution suggest that its luminosity was substantially reduced 2-4 billion years ago, which is inconsistent with substantial evidence for warm and wet conditions in theExpand
Testing Late Cretaceous astronomical solutions in a 15 million year astrochronologic record from North America
Abstract Astronomically-forced insolation cycles (“Milankovitch cycles”) serve as a primary control on climate, and when preserved in the stratigraphic record, they provide a high-resolution in situExpand
Observational constraints on an undiscovered giant planet in our solar system
Abstract Over the last few years, the action of an undiscovered giant planet has been considered in many works to explain the orbital properties of the most distant known objects in our solar system.Expand
Analytically calculated post-Keplerian range and range-rate perturbations: the solar Lense–Thirring effect and BepiColombo
We analytically calculate the time series for the perturbations $\Delta\rho(t),~\Delta\dot\rho(t)$ induced by a general disturbing acceleration $\boldsymbol{A}$ on the mutual range $\rho$ andExpand
Cyclostratigraphy and Astrochronology in 2018
Abstract After more than a century of doubt and equivocation, cyclostratigraphy – the stratigraphic record of astronomically forced paleoclimatic change – has come to be widely accepted in theExpand
Astrochronology and radio-isotopic dating of the Alano di Piave section (NE Italy), candidate GSSP for the Priabonian Stage (late Eocene)
Abstract We have carried out an integrated chronostratigraphic analysis of the Alano di Piave section, proposed GSSP for the Bartonian/Priabonian boundary (late Eocene). Age constraints were derivedExpand
A lower to middle Eocene astrochronology for the Mentelle Basin (Australia) and its implications for the geologic time scale
The geologic time scale for the Cenozoic Era has been notably improved over the last decades by virtue of integrated stratigraphy, combining high-resolution astrochronologies, biostratigraphy andExpand
Orbital tuning for the middle Eocene to early Oligocene Monte Cagnero Section (Central Italy): Paleoenvironmental and paleoclimatic implications
Abstract During the middle Eocene to early Oligocene Earth transitioned from a greenhouse to an icehouse climate state. The interval comprises the Middle Eocene Climatic Optimum (MECO; ~40 Ma) and aExpand

On the Dynamical Stability of the Solar System
A long-term numerical integration of the classical Newtonian approximation to the planetary orbital motions of the full solar system (Sun + eight planets), spanning 20 Gyr, was performed. The resultsExpand

Due to the chaotic nature of the Solar System, the question of its long-term stability can only be answered in a statistical sense, for instance, based on numerical ensemble integrations of nearbyExpand

We present here a new solution for the astronomical computation of the orbital motion of the Earth spanning from 0 to −250 Myr. The main improvement with respect to our previous numerical solutionExpand
A long-term numerical solution for the insolation quantities of the Earth
We present here a new solution for the astronomical computation of the insolation quantities on Earth spanning from -250 Myr to 250 Myr. This solution has been improved with respect to La93 (LaskarExpand
Constraints on Planet Nine’s Orbit and Sky Position within a Framework of Mean-motion Resonances
A number of authors have proposed that the statistically significant orbital alignment of the most distant Kuiper Belt Objects (KBOs) is evidence of an as-yet undetected planet in the outer solarExpand
Successive Refinements in Long-Term Integrations of Planetary Orbits
We report on accurate, long-term numerical simulations of the orbits of the major planets in our solar system. The equations of motion are directly integrated by a Stormer multistep scheme, which isExpand
Existence of collisional trajectories of Mercury, Mars and Venus with the Earth
Numerical simulations of the evolution of the Solar System over 5 Gyr, including contributions from the Moon and general relativity find that one per cent of the solutions lead to a large increase in Mercury’s eccentricity—an increase large enough to allow collisions with Venus or the Sun. Expand
