New Completeness Methods for Estimating Exoplanet Discoveries by Direct Detection [PDF]
Astrophysical Journal, 2010 We report new methods for evaluating realistic observing programs that search stars for planets by direct imaging, where observations are selected from an optimized star list, and where stars can be observed multiple times.

Five Methods of Exoplanet Detection
Journal of Physics: Conference Series, 2021 Abstract The study of exoplanetary systems can help us understand the formation and evolution of the solar system itself and search for terrestrial planets in the habitable and extrasolar lives in exoplanetary systems. Exoplanets have become an important area of astrophysics in the last two decades.

Bayesian Methods for Joint Exoplanet Transit Detection and Systematic Noise Characterization [PDF]
Astronomical Journal, 2020 Abstract The treatment of systematic noise is a significant aspect of transit exoplanet data processing due to the signal strength of systematic noise relative to a transit signal. Typically, the standard approach to transit detection is to estimate and remove systematic noise independently of and prior to a transit detection test.

VaTEST. II. Statistical Validation of 11 TESS-detected Exoplanets Orbiting K-type Stars
The Astronomical Journal, 2023 NASA’s Transiting Exoplanet Survey Satellite (TESS) is an all-sky survey mission designed to find transiting exoplanets orbiting nearby bright stars. It has identified more than 329 transiting exoplanets, and almost 6000 candidates remain unvalidated. In

Statistical Methods for Exoplanet Detection with Radial Velocities
Annual Review of Statistics and Its Application, 2023 Exoplanets can be detected with various observational techniques. Among them, radial velocity (RV) has the key advantages of revealing the architecture of planetary systems and measuring planetary mass and orbital eccentricities. RV observations are poised to play a key role in the detection and characterization of Earth twins.

OGLE-2019-BLG-1180Lb: Discovery of a Wide-orbit Jupiter-mass Planet around a Late-type Star
The Astronomical Journal, 2023 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 unambiguous cusp-passing and caustic-crossing anomalies, which were caused by a ...
