We fit a dynamical model to Kepler systems that contain four or more transiting planets using the analytic method AnalyticLC and obtain physical and orbital parameters for 101...

The phenomenon of transit depth variability offers a pathway through which processes such as exoplanet atmospheric activity and orbital dynamics can be studied. In this work we...

TOI-1899b is a rare exoplanet, a temperate warm Jupiter orbiting an M-dwarf, first discovered by Canas et al. (2020) from a TESS single-transit event. Using new radial...

Both direct and indirect methods of exoplanet detection rely upon detailed knowledge of the potential host stars. Such stellar characterization allows for accurate extraction of...

Mass, radius, and age measurements of young (<~100Myr) planets have the power to shape our understanding of planet formation. However, young stars tend to be extremely...

We report the discovery and Doppler mass measurement of a 7.4days 2.3R{Earth} mini-Neptune around a metal-poor K-dwarf BD+29-2654 (TOI-2018). Based on a high-resolution...

Thousands of exoplanet detections have been made over the last 25 years using Doppler observations, transit photometry, direct imaging, and astrometry. Each of these methods is...

We present the stellar and planetary properties for 85 TESS Objects of Interest (TOIs) hosting 108 planet candidates that compose the TESS-Keck Survey (TKS) sample. We combine...

We report the confirmation of a TESS-discovered transiting super-Earth planet orbiting a mid-G star, HD307842 (TOI-784). The planet has a period of 2.8days, and the radial...

Most existing exoplanets are discovered using validation techniques rather than being confirmed by complementary observations. These techniques generate a score that is...

We report the discovery and characterization of three giant exoplanets orbiting solar-analog stars, detected by the TESS space mission and confirmed through ground-based...

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...

Wolf-359 (CN-Leo, GJ-406, Gaia-DR3-3864972938605115520) is a low-mass star in the fifth-closest neighboring system (2.41pc). Because of its relative youth and proximity,...

We report on the discovery and analysis of the planetary microlensing event OGLE-2019-BLG-1180 with a planet-to-star mass ratio q~0.003. The event OGLE-2019-BLG-1180 has...

Large-scale exoplanet surveys like the Transiting Exoplanet Survey Satellite (TESS) mission are powerful tools for discovering large numbers of exoplanet candidates....

We present a transit-timing variation (TTV) and planetary atmosphere analysis of the Neptune-mass planet HAT-P-26 b. We present a new set of 13 transit light curves from optical...

The Search for Extraterrestrial Intelligence aims to find evidence of technosignatures, which can point toward the possible existence of technologically advanced...

We present the discovery of TOI-1420b, an exceptionally low-density ({rho}=0.08{+/-}0.02g/cm^3^) transiting planet in a P=6.96days orbit around a late G-dwarf star. Using...

Previous studies of the exoplanet LTT1445Ac concluded that the light curve from the Transiting Exoplanet Survey Satellite (TESS) was consistent with both grazing and nongrazing...

Understanding orbital obliquities, or the misalignment angles between a star's rotation axis and the orbital axis of its planets, is crucial for unraveling the mechanisms of...
