EXOPLANET DETECTION METHODS: AN OVERVIEW OF TECHNIQUES AND LIMITATIONS

Kosmìčna nauka ì tehnologìâ
This 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

Research on the Methods of Exoplanet Detection and Discussion on Correlations and Flaws

Transactions on Computer Science and Intelligent Systems Research
The search for exoplanets, particularly Earth-like planets, has garnered significant attention as potential second homes for human beings. Highlights of the urgency of finding alternative habitable planets due to the dire consequences of global warming and climate change on Earth.

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.

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-dataŽ, then uses allof them in a Maximum ...

A radiometric model for demonstration of exoplanets detection by the transit method [PDF]

Physics Education
Abstract This work describes an exact radiometric model for experimental demonstrators of the detection of exoplanets by the transit method. This model generalises the calculation of the depth of occultation from the standard transit method to the case of a finite size demonstrator apparatus.

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 ...

Exoplanet Detection of the Kepler Space Telescope through the Transit Method

Transactions on Computer Science and Intelligent Systems Research
With the exploitation of resources and environmental pollution, the Earth has suffered countless damages. As a result, there are more and more environmental problems such as the greenhouse effect and desertification. People only have one home, one Earth, so if the Earth becomes extinct, people will not exist anymore.

Direct Optical Detection of Microorganisms in Exoplanet Atmospheres: Methods

, 2016
The purpose of this project is to develop an optical method for detecting the presence of life, specifically microorganisms, in the atmosphere of an exoplanet. We are developing algorithms that distinguish between aerosols of biological origin (microorganisms) from aerosols of non-biological origin (dust, hydrosols, etc.) using analysis of their ...

Exoplanet Detection Techniques: From Classical Methods to Modern Machine Learning Approaches

Theoretical and Natural Science
Since the discovery of 51 Pegasi b in 1995, exoplanet research has evolved from serendipitous radial-velocity detections to large-scale surveys employing transit photometry, microlensing, astrometry, and high-contrast direct imaging.
