RBN-World: Sub-Symbolic Artificial Chemistry for Artificial Life [PDF]

, 2011
Artificial Chemistry seeks to explore how life-like systems can emerge from a pre-biotic environment. This thesis begins with the background of this research area and a re-implementation of an existing Artificial Chemistry as a case study.

Toward High-precision Mass Measurements of Two Sub-Neptunes in the K2-266 Planetary System Through Transit Timing

The Astronomical Journal
Sub-Neptunes have been found to be one of the most common types of exoplanets, yet their physical parameters and properties are poorly determined and in need of further investigation.

Architecture Classification for Extrasolar Planetary Systems

The Astronomical Journal
This paper presents a classification framework for the architectures of planetary systems based on a complete survey of the confirmed exoplanet population. With nearly 6000 confirmed exoplanets discovered, including more than 300 multiplanet systems with

Sub-Neptunes Show a Stronger Correlation with Cold Jupiters than Super-Earths Especially in Metal-rich Systems

The Astrophysical Journal Letters
The correlation between the inner small planets and cold giants encodes the formation and evolution of planetary systems. It remains unclear if the correlation differs on the two sides of the radius valley.

Four New Exoplanets and Hints of Additional Substellar Companions to Exoplanet Host Stars [PDF]

, 2007
We present four new exoplanets: HIP 14810b and HIP 14810c, HD 154345b, and HD 187123c. The two planets orbiting HIP 14810, from the N2K project, have masses of 3.9 and 0.76 M_J.

Uncertainty Estimation in Exoplanet System Parameters

Research Notes of the AAS
Abstract The NASA Exoplanet Archive contains published data for various stellar and planetary parameters, based on the combined work of hundreds of research teams. For cases where a parameter has been estimated multiple times, the opportunity exists to compare the variance in an estimated parameter value with the reported uncertainties ...

Eccentricity Evolution of Warm Jupiters: The Role of Distant Perturbers and nearby Companions

The Astrophysical Journal
Warm Jupiters (WJs)—giant exoplanets with orbital periods between 10 and 200 days—exhibit a broad range of eccentricities and are often accompanied by nearby low-mass planets.
