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.

The Comparison of Five Methods of Detecting Exoplanets
Highlights in Science, Engineering and Technology, 2023 Detecting exoplanets has become a hot topic, where various detection scenarios have been proposed. Five of these methods have all found more than 50 exoplanets, which are the transit method, the radial velocity method, the microlensing method, the imaging method, and the timing method.

Variability of Known Exoplanet Host Stars Observed by TESS
The Astronomical Journal, 2023 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 planetary properties, as well as contributing to our overall understanding ...

Optimal method for exoplanet detection by spectral and angular differential imaging [PDF]
SPIE Proceedings, 2010 ABSTRACT In the context of the SPHERE planet nder project, we further develop and characterize a recently proposedmethod for the ecient direct detection of exoplanets f rom the ground using spectral and angular dierentialimaging. The method, called ANDROMEDA, combines images appropriately into pseudo-data, then uses allof them in a Maximum ...

Detection of Exoplanets based on the Transit Method
Highlights in Science, Engineering and Technology, 2023 Exoplanets are planets orbiting a star other than the Sun. These exoplanets may exist in many different forms, such as a hot Jupiter and super earth. Detecting is the first step to further studying the properties of these exoplanets. In this paper, based on data of star Qatar-1 gathered from July 22nd 2022, a light flux curve is developed during the ...

A new method for finding nearby white dwarfs exoplanets and detecting biosignatures
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT We demonstrate that the James Webb Space Telescope (JWST) can detect infrared (IR) excess from the blended light spectral energy distribution of spatially unresolved terrestrial exoplanets orbiting nearby white dwarfs. We find that JWST is capable of detecting warm (habitable-zone; Teq = 287 K) Earths or super-Earths and hot ...

Assessing telluric correction methods for Na detections with high-resolution exoplanet transmission spectroscopy [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT Using high-resolution ground-based transmission spectroscopy to probe exoplanetary atmospheres is difficult due to the inherent telluric contamination from absorption in Earth’s atmosphere. A variety of methods have previously been used to remove telluric features in the optical regime and calculate the planetary transmission ...
