我们报道凌日热木星KPS-1b的发现。这颗系外行星每1.7天围绕一颗V = 13.0的k1型主序恒星公转一圈，质量为1.090−0.087 + 0.086 MJup，半径为1.03−0.12 + 0.13 RJup。这一发现是由Kourovka行星搜索（KPS）项目的原型完成的，该项目使用了一个业余天文学家使用现成且相对便宜的设备收集的宽视场CCD数据。本文介绍了发现KPS-1b所使用的设备和观测技术，以及索菲光谱仪的光谱观测和1米级望远镜的高精度光度测定对其进行的表征。我们还概述了KPS项目向银河面系外行星调查的演变。KPS-1b的发现代表着业余天文学家对新兴的系外行星学领域的贡献又迈出了重要的一步。
We report the discovery of the transiting hot Jupiter KPS-1b. This exoplanet orbits a V = 13.0 K1-type main-sequence star every 1.7 days, has a mass of 1.090 − 0.087 + 0.086 MJup and a radius of 1.03 − 0.12 + 0.13 RJup. The discovery was made by the prototype Kourovka Planet Search (KPS) project, which used wide-field CCD data gathered by an amateur astronomer using readily available and relatively affordable equipment. Here we describe the equipment and observing technique used for the discovery of KPS-1b, its characterization with spectroscopic observations by the SOPHIE spectrograph and with high-precision photometry obtained with 1 m class telescopes. We also outline the KPS project evolution into the Galactic Plane eXoplanet survey. The discovery of KPS-1b represents a new major step of the contribution of amateur astronomers to the burgeoning field of exoplanetology.
