KOI-3158: The oldest known system of terrestrial-size planets

EPJ Web of Conferences, 2015
The first discoveries of exoplanets around Sun-like stars have fueled efforts to find ever smaller worlds evocative of Earth and other terrestrial planets in the Solar System. While gas-giant planets appear to form preferentially around metal-rich stars,

Solar system planet formation

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

Eccentricity Distribution beyond the Snow Line and Implications for Planetary Habitability

The Astrophysical Journal Letters
A 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 ...

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 ...

The Link between Athor and EL Meteorites Does Not Constrain the Timing of the Giant Planet Instability

The Astrophysical Journal Letters
The 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 ...

Making Extrasolar Planets From Solar Systems Via Dynamical Interactions

, 2010
Most stars form in some sort of stellar cluster or association. In such environments the number density of stars is much higher than in the solar neighbourhood, which means that close encounters between stars may be relatively common.

JWST COMPASS: A NIRSpec/G395H Transmission Spectrum of the Sub-Neptune TOI-836c

The Astronomical Journal
Planets between the sizes of Earth and Neptune are the most common in the Galaxy, bridging the gap between the terrestrial and giant planets in our solar system.
