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 ...

Chemical modeling of exoplanet atmospheres [PDF]

, 2014
International audienceThe past twenty years have revealed the diversity of planets that exist in the Universe. It turned out that most of exoplanets are different from the planets of our Solar System and thus, everything about them needs to be explored ...

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

Balloon exoplanet nulling interferometer (BENI) [PDF]

, 2009
SPIE Optical Engineering + Applications, 2009, San Diego, California, United StatesWe evaluate the feasibility of a balloon-borne nulling interferometer to detect and characterize an exosolar planet and the surrounding debris disk.

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.

Exoplanet Catalogue [PDF]

An exoplanet is a planet that orbits another star other than the Sun; since 1988, more than 4,300 of them have been confirmed. This catalogue provides a visual way to visualise exoplanets in their solar systems, together with their habitable zones.

Resonant and Ultra-short-period Planet Systems Are at Opposite Ends of the Exoplanet Age Distribution

The Astronomical Journal
Exoplanet systems are thought to evolve on secular timescales over billions of years. This evolution is impossible to directly observe on human timescales in most individual systems.

System study of EPICS: the exoplanets imager for the E-ELT

SPIE Proceedings, 2010
ESO and a large European consortium completed the phase-A study of EPICS, an instrument dedicated to exoplanets direct imaging for the EELT. The very ambitious science goals of EPICS, the imaging of reflected light of mature gas giant exoplanets around bright stars, sets extremely strong requirements in terms of instrumental contrast achievable.

A Model for Astrometric Detection and Characterization of Multi-Exoplanet Systems [PDF]

, 2016
In this thesis, we develop an approximate linear model of stellar motion in multiplanet systems as an aid to observers using the astrometric method to detect and characterize exoplanets.
