Origin and Formation of Planetary Systems [PDF]

Astrobiology, 2010
To estimate the occurrence of terrestrial exoplanets and maximize the chance of finding them, it is crucial to understand the formation of planetary systems in general and that of terrestrial planets in particular. We show that a reliable formation theory should not only explain the formation of the Solar System, with small terrestrial planets within a

The protoplanetary disc HD 163296 as observed by ALMA

Vietnam Journal of Science, Technology and Engineering, 2022
HD 163296 is one of the few protoplanetary discs displaying rings in the dust component. The present work uses ALMA observations of the 0.9 mm continuum emission, which have significantly better spatial resolution (~8 au) than previously available, to ...

Sensitivity of elastic thickness to water in the Martian lithosphere

Progress in Earth and Planetary Science, 2019
Ancient Mars likely hosted oceans similar to those on Earth; however, such water is not presently observed on Mars. One possible explanation for the lack of present-day oceans is that surface water was transported into and stored within the interior of ...

A Review on Substellar Objects below the Deuterium Burning Mass Limit: Planets, Brown Dwarfs or What?

Geosciences, 2018
“Free-floating, non-deuterium-burning, substellar objects” are isolated bodies of a few Jupiter masses found in very young open clusters and associations, nearby young moving groups, and in the immediate vicinity of the Sun.

Microlensing Searches for Exoplanets

Geosciences, 2018
Gravitational microlensing finds planets through their gravitational influence on the light coming from a more distant background star. The presence of the planet is then inferred from the tell-tale brightness variations of the background star during the

Exoplanet Predictions Based on Harmonic Orbit Resonances

Galaxies, 2017
The current exoplanet database includes 5454 confirmed and candidate planets observed with the Kepler mission. We find 932 planet pairs from which we extract distance and orbital period ratios.

Towards planetary health systems: a manifesto for a revised quadruple aim for healthcare improvement

Global Sustainability
Non-technical summary Healthcare systems significantly impact the environment, which in turn affects human health. To address this, we propose to revise a popular framework for healthcare improvement, by introducing the advancement of planetary health ...

Carbonate clumped isotope thermometry of fault rocks and its possibilities: tectonic implications from calcites within Himalayan Frontal Fold-Thrust Belt

Progress in Earth and Planetary Science, 2021
Disentangling the temperature and depth of formation of fault rocks is critical for understanding their rheology, exhumation, and the evolution of fault zones.
