Xingming Observatory Exoplanet Search project (XESP)

Introduction

Xingming Observatory Exoplanet Search Project (XESP) is one of the sky survey mission hosted by Xingming Observatory(details) aimming to discover exoplanets around nearby bright stars. The project mainly searches for candidates by mining public data (TESS, Kepler etc.), and would use Ningbo Education Xinjiang Observatory Telescope (NEXT, details) for follow-up observation. Dozons of exoplanet candidates with suitable luminosity would be observed and analysed. The members of the XESP team have rich experience in sky survey and variable star search, and have discovered hundreds of new variable stars(details).

Team members：Guoyou Sun, Wenjie Zhou, Mi Zhang, Jingyuan Zhao, Yanxi Li, Xing Gao (Xingming Obs)
