Statistical Methods for Exoplanet Detection with Radial Velocities [PDF]
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.

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.

New Completeness Methods for Estimating Exoplanet Discoveries by Direct Detection [PDF]
The 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.

Bayesian Methods for Joint Exoplanet Transit Detection and Systematic Noise Characterization [PDF]
The 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.

EXOPLANET DETECTION METHODS: AN OVERVIEW OF TECHNIQUES AND LIMITATIONS
Kosmìčna nauka ì tehnologìâThis article provides an overview of the main methods used in the search for exoplanets, including the transit method, radial velocity, astrometry, and direct imaging. Through the analysis of various sources, the applicability, strengths, and inherent limitations of each technique are assessed. The transit method, responsible for approximately 75 % of

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

Combining Multi-Spectral Data With Statistical and Deep-Learning Models for Improved Exoplanet Detection in Direct Imaging at High Contrast [PDF]
European Signal Processing Conference, 2023 Exoplanet detection by direct imaging is a difficult task: the faint signals from the objects of interest are buried under a spatially structured nuisance component induced by the host star.

deep PACO: Combining statistical models with deep learning for exoplanet detection and characterization in direct imaging at high contrast [PDF]
Monthly notices of the Royal Astronomical Society, 2023 Direct imaging is an active research topic in astronomy for the detection and the characterization of young sub-stellar objects. The very high contrast between the host star and its companions makes the observations particularly challenging.
