论文摘要
我们报告了一名新的外部候选候选者的发现，该候选人绕着Star GJ 3470绕。基于此参数，我们计算半径为9.2地球半径，该半径对应于土星样系外行星的大小。我们还估计一个轨道周期为66天，将外部球星放在宜居区域内，靠近地球等效辐射的轨道距离。还报道了另一个不属于GJ 3470 b的潜在转移。尽管我们对GJ 3470 C的候选人仍必须得到科学界的确认，但该发现代表了系外行星研究的一个转折点，因为它是由业余天文学家管理的国际项目发现的第一位候选人。
We report the discovery of a new exoplanet candidate orbiting the star GJ 3470. A total of three transits were detected by OKSky Observatory: the first one on December 23, 2019, the second one on February 27, 2020, and the third one on May 3, 2020. We estimate an average transit depth of 0.84 percent and duration of 1 hour and 2 minutes. Based on this parameter, we calculate a radius of 9.2 Earth radii, which would correspond to the size of a Saturn-like exoplanet. We also estimate an orbital period of 66 days that places the exoplanet inside the habitable zone, near the orbital distance at Earths equivalent radiation. Another twelve potential transits that do not belong to GJ 3470 b are also reported. Despite our candidate for GJ 3470 c still has to be confirmed by the scientific community, the discovery represents a turning point in exoplanet research for being the first candidate discovered through an international project managed by amateur astronomers.
