ExoplanetExplorer: Contextual Visualization of Exoplanet Systems

2023 IEEE Visualization and Visual Analytics (VIS), 2023
An exoplanet is a planet outside of our solar system. Researchers study known exoplanets and gather data about them through observations and derived data. Ongoing efforts involve finding planets with an environment that supports life, which likely exists

Exoplanet Systems and Their Stars

2018
This chapter highlights the amazing diversity of exoplanet worlds: planets can orbit neutron stars and giant stars, evaporate in the heat of their stars or have deep oceans, and may suffer from everlasting daysides and nightsides. A few enjoy two or more suns, and some bear a rough similarity to Earth with possible liquid water on their surface.

Evidence for Low-level Dynamical Excitation in Near-resonant Exoplanet Systems* [PDF]

Astronomical Journal, 2023
The geometries of near-resonant planetary systems offer a relatively pristine window into the initial conditions of exoplanet systems. Given that near-resonant systems have likely experienced minimal dynamical disruptions, the spin–orbit orientations of ...

The Berlin Exoplanet Search Telescope System

Publications of the Astronomical Society of the Pacific, 2004
We describe a small telescope system, the Berlin Exoplanet Search Telescope (BEST), dedicated to the search for planetary transits of Jupiter-sized planets on close-in orbits. This system consists of a commercial 20 cm telescope equipped with a 2048 x2048 pixel CCD.

The Orbital Geometries and Stellar Obliquities of Exoplanet-hosting Multistar Systems

Astronomical Journal
The current orbital geometries of exoplanet systems offer a fossilized record of the systems’ dynamical histories. A particularly rich set of dynamical mechanisms is available to exoplanets residing in multistar systems, which may have their evolution ...

Polarimetry of the exoplanet system 51 Pegasi

Solar System Research, 2013
Two-year BVRI polarimetric monitoring of the exoplanet system 51 Peg has been carried out, indicating that there is no orbital phase-dependent periodic variability in linear polarization with amplitudes greater than 0.04% in the R and I bands. The mean value of one of the Stokes parameters is statistically significant and nonzero, being equal to 0.017 ±

Planet-Planet Interactions in Exoplanet Systems

2022
The gravitational interactions of planets in multiplanetary systems can have effects ranging from tiny orbital alterations to severe instability and everything in between. In this thesis, I discuss three applications of planet-planet interactions. First, I demonstrate using N-body simulations that a commonly-used analytical approximation can have large
