Abstract

With the advancement of human exploration of the universe, the detection of exoplanets has become one of the core areas in astronomy. The search for exoplanets and potential signs of life holds critical significance for understanding galactic systems across the cosmos and the origins of life. This study analyses the current mainstream detection methods, including the transit method, radial velocity method, and Artificial Intelligence-based (AI-based) detection algorithms. It elaborates on their principles, technical advantages, limitations, and major research achievements to date. According to the analysis, the transit method is highly sensitive to the orbital inclination of planetary systems. While it can accurately determine a planet's radius, it is unable to provide continuous long-term observations of radial velocity. The radial velocity method can estimate planetary mass but is primarily effective for detecting massive planets in close proximity to their host stars. Due to significant interference from stellar activity, this method poses considerable challenges in practice. In contrast, Artificial Intelligence (AI) algorithms leverage deep learning to integrate multiple data sources, enabling improved identification and analysis, thereby substantially enhancing detection accuracy. These findings contribute to the development of an intelligent astronomical observation system that integrates multiple technologies, thereby advancing scientific research in exoplanet detection.
