Exoplanet-induced Radio Emission from M Dwarfs [PDF]
, 2018 We consider the magnetic interaction of exoplanets orbiting M dwarfs, calculating the expected Poynting flux carried upstream along Alfvén wings to the central star.

Validating AU Microscopii d with Transit Timing Variations
The Astronomical Journal, 2023 AU Mic is a young (22 Myr), nearby exoplanetary system that exhibits excess transit timing variations (TTVs) that cannot be accounted for by the two known transiting planets nor stellar activity.

DEBRIS DISKS INKEPLEREXOPLANET SYSTEMS [PDF]
The Astrophysical Journal, 2012 The Kepler Mission recently identified 997 systems hosting candidate extrasolar planets, many of which are super-Earths. Realizing these planetary systems are candidates to host extrasolar asteroid belts, we use mid-infrared data from the Wide-field Infrared Survey Explorer (WISE) to search for emission from dust in these systems.

ESA-Gaia Multiplicity Study of Exoplanet Host Stars [PDF]
, 2021 The latest results of a survey are presented, which explores the data releases of the ESA-Gaia mission, in order to study the multiplicity of exoplanet host stars, located at distances closer than about 625 pc around the Sun.

Results of the astrometry and direct imaging testbed for exoplanet detection [PDF]
, 2017 Measuring masses of long-period planets around F, G, and K stars is necessary to characterize exoplanets and assess their habitability. Imaging stellar astrometry offers a unique opportunity to solve radial velocity system inclination ambiguity and ...

The Exoplanet Orbit Database [PDF]
, 2011 We present a database of well-determined orbital parameters of exoplanets, and their host stars’ properties. This database comprises spectroscopic orbital elements measured for 427 planets orbiting 363 stars from radial velocity and transit measurements ...

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.

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.
