This thesis assesses the influence of astronomical phenomena on the Earth's biosphere and climate. I examine in particular the relevance of both the path of the Sun through the Galaxy and the evolution of the Earth's orbital parameters in modulating non-terrestrial mechanisms. I build models to predict the extinction rate of species, the temporal variation of the impact cratering rate and ice sheet deglaciations, and then compare these models with other models within a Bayesian framework. I… 
Finding the imprints of stellar encounters in long-period comets
The solar system's Oort cloud can be perturbed by the Galactic tide and by individual passing stars. These perturbations can inject Oort cloud objects into the inner parts of the solar system, where
Was Proxima captured by Alpha Centauri A and B
The nearest stellar system consists of the stars Proxima, alpha Centauri A and B and at least one planet Proxima b. The habitability of Proxima b and any other planets are likely to be significantly


Dynamical Paleoclimatology: Generalized Theory Of Global Climate Change
The book discusses the ideas and creates a framework for building toward a theory of paleoclimate. Using the rich and mounting array of observational evidence of climatic changes from geology,

Celestial Mechanics and Dynamical Astronomy Equations for the orbital elements : Hidden symmetry
We revisit the Lagrange and Delaunay systems of equations for the orbital elements, and point out a previously neglected aspect of these equations: in both cases the orbit resides on a certain
