# Detecting exoplanets with FAST?

## TL;DR

This paper reviews potential radio emission mechanisms from exoplanets, evaluates past search efforts, and discusses how FAST telescope observations could improve detection strategies, especially through polarization and high duty-cycle measurements.

## Contribution

It provides a comprehensive overview of radio emission scenarios from exoplanets and proposes optimized observation strategies using FAST to enhance detection prospects.

## Key findings

- Radio emissions above 70 MHz are promising for detection.
- Past searches have yielded limited results, highlighting challenges.
- FAST's capabilities can significantly improve detection sensitivity.

## Abstract

We briefly review the various proposed scenarios that may lead to nonthermal radio emissions from exoplanetary systems (planetary magnetospheres, magnetosphere-ionosphere and magnetosphere-satellite coupling, and star-planet interactions), and the physical information that can be drawn from their detection. The latter scenario is especially favorable to the production of radio emission above 70\,MHz. We summarize the results of past and recent radio searches, and then discuss FAST characteristics and observation strategy, including synergies. We emphasize the importance of polarization measurements and a high duty-cycle for the very weak targets that radio-exoplanets prove to be.
