Planetary Systems Formation and the Diversity of Extrasolar Systems [PDF]

Proceedings of the International Astronomical Union, 2010
With the end of answer questions as, how common are planetary systems like our own in the Universe? and What is the diversity of planetary systems that we could find in the universe?, we develop a semi-analytical model for computing planetary systems ...

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.

Theoretical models of planetary system formation II. Post-formation evolution [PDF]

Astronomy & Astrophysics, 2015
Aims. We extend the results of planetary formation synthesis by computing the long-term evolution of synthetic systems from the clearing of the gas disk into the dynamical evolution phase. Methods.

The Formation of Planetary Systems With SPICA [PDF]

Publications of the Astronomical Society of Australia, 2021
Abstract In this era of spatially resolved observations of planet-forming disks with Atacama Large Millimeter Array (ALMA) and large ground-based telescopes such as the Very Large Telescope (VLT), Keck, and Subaru, we still lack statistically relevant information on the quantity and composition of the material that is building the planets, such as ...

Chemical Clues on the Formation of Planetary Systems [PDF]

Proceedings of the International Astronomical Union, 2010
AbstractTheoretical studies suggest that C/O and Mg/Si are the most important elemental ratios in determining the mineralogy of terrestrial planets. The C/O ratio controls the distribution of Si among carbide and oxide species, while Mg/Si gives information about the silicate mineralogy.

Searching For the t=0 of Planetary System Formation [PDF]

EPJ Web of Conferences, 2022
The composition of bodies in the solar system points to strong gradients in the volatile content within solid bodies hinting at the presence of gas-ice transitions across sublimation fronts in the young formative stages when the gas-rich disk was present.

An Analytical Theory for the Growth from Planetesimals to Planets by Polydisperse Pebble Accretion

The Astrophysical Journal, 2023
Pebble accretion is recognized as a significant accelerator of planet formation. Yet only formulae for single-sized (monodisperse) distribution have been derived in the literature.
