This framework examines how planets form in their solar systems and if physics and mechanisms can describe the formations of planets without relying on stochastic events. In this Framework I try to explain planetary formation primarily with centrifuge like effects of solar rotation and the laws of physics hard at work. This framework was developed with

Advances in causal discovery methods for ecological time series
Biological Reviews, EarlyView.ABSTRACT Recent advances in data collection technologies (e.g. automated sensor networks, satellite remote sensing, and high‐throughput sequencing) have greatly expanded the availability of ecological time series, enabling new opportunities for causal analyses in dynamic ecosystems.

Properties of mass-loading shocks, 2. Magnetohydrodynamics
, 1992 The one-dimensional magnetohydrodynamics of shocked flows subjected to significant mass loading are considered. Recent observations at comets Giacobini-Zinner and Halley suggest that simple nonreacting MHD is an inappropriate description for active ...

Circular Economy Pathways for Airport Climate Change Mitigation
Business Strategy and the Environment, EarlyView.ABSTRACT Airport operators face growing climate‐change pressures; the circular economy offers pathways to reduce impacts and recover resources. We examine how airport operators apply the circular economy in practice. We use an exploratory qualitative multicase design based on practitioner‐generated documents (e.g., press releases and sustainability ...

The Astrophysical Journal LettersThe asteroid Athor, residing today in the inner main asteroid belt, has been recently identified as the source of EL enstatite meteorites to Earth. It has been argued that Athor formed in the terrestrial region—as indicated by a similarity in isotopic ...

A light carbon isotope composition for the Sun
Nature Communications, 2018 The Sun’s light stable isotopes compositions can help us understand how our solar system formed. Here, the authors find that solar C is depleted relative to bulk Earth indicating that the 13C enrichment of the terrestrial planets is from CO self ...

Business Strategy and the Environment, EarlyView.ABSTRACT Despite more than 20 years of research into sustainable tourism, the environmental impact of the UK hospitality sector remains high. A growing body of research into the concept of a circular economy (CE) demonstrates that transitioning to this way of working has significant benefits both for the environment and business outcomes.

Eccentricity Distribution beyond the Snow Line and Implications for Planetary Habitability
The Astrophysical Journal LettersA fundamental question in the study of planetary system demographics is: how common is the solar system architecture? The primary importance of this question lies in the potential of planetary systems to create habitable environments, and dissecting the ...
