Stability analysis of three exoplanet systems [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT The orbital solutions of published multiplanet systems are not necessarily dynamically stable on time-scales comparable to the lifetime of the system as a whole. For this reason, dynamical tests of the architectures of proposed exoplanetary systems are a critical tool to probe the stability and feasibility of the candidate ...

A Search for wide visual companions of exoplanet host stars - The Calar Alto Survey [PDF]
, 2006 We have carried out a search for co-moving stellar and substellar companions around 18 exoplanet host stars with the infrared camera MAGIC at the 2.2m Calar Alto telescope, by comparing our images with images from the all sky surveys 2MASS, POSS I and II.

The Exoplanet Population Observation Simulator. II -- Population Synthesis in the Era of Kepler [PDF]
, 2019 The collection of planetary system properties derived from large surveys such as Kepler provides critical constraints on planet formation and evolution.

The Astronomical Journal, 2023 We present the discovery from the TESS mission of two giant planets transiting M-dwarf stars: TOI 4201 b and TOI 5344 b. We also provide precise radial velocity measurements and updated system parameters for three other M dwarfs with transiting giant ...

Solar System Planets and Exoplanets
, 2021 Solar System planets have been studied for centuries, but the observation of exoplanets is only a few decades old. Consequently, knowledge of exoplanets is considerably more limited than Solar System planets. This chapter reviews the essential characteristics of Solar System planets and associated data derived from a variety of observational approaches.

Radio-loud Exoplanet-exomoon Survey: GMRT Search for Electron Cyclotron Maser Emission
The Astronomical Journal, 2022 We conducted the first dedicated search for signatures of exoplanet–exomoon interactions using the Giant Metrewave Radio Telescope (GMRT) as part of the radio-loud exoplanet-exomoon survey.

HD3651B: the first directly imaged brown dwarf companion of an exoplanet host star [PDF]
, 2006 In the course of our ongoing multiplicity study of exoplanet host stars we detected a faint companion located at ~43arcsec (480AU physical projected separation) north-west of its primary -- the exoplanet host star HD3651 at 11pc.

Resilient habitability of nearby exoplanet systems [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 ABSTRACT We investigate the possibility of finding Earth-like planets in the habitable zone of 34 nearby FGK-dwarfs, each known to host one giant planet exterior to their habitable zone detected by RV. First we simulate the dynamics of the planetary systems in their present day configurations and determine the fraction of stable ...
