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)

TOI XXXX.0X means that the deleted TOI was retired due to a too-large △RV that has no chance to support the candidate to be a exoplanet, or due to a hopeless rotation (ROT) of the host star makes us hard to define the mass of the candidate.

TOI XXXX.0X indicates that the deleted TOI corresponds to a known exoplanet, but we do not have the discovery credit due to various reasons.

TOI XXXX.0X means that it is a confirmed exoplanet, and we should share the discovery credit.

 

Acknowledgement

In the process of exoplanets searching, we used two very useful software: VStar and Lctools. Their excellent design and powerful functions have improved our efficiency a lot. We would like to express our sincere thanks to these two software and the teams that developed them.
