论文摘要
我们从统计上验证了使用Dave和Triceratops应用两步审查技术的热海王星候选者样本。我们在通过$ p \ leq 4 $ d和$ 3R_ \ oplus \ leq r \ leq r \ leq 5r_ \ oplus $定义的参数区域中的过渡系外行星调查卫星（TESS）档案中进行了250个类似于Transit的事件的系统验证。通过我们的分析，我们确定了18个热门海王星大小的候选人，其假阳性概率$ <50 \％$。这些星球候选者中的九个仍然需要得到确认。对于九个目标中的每个目标，我们都使用Ariadne并通过将Lightcurves与Juliet软件包拟合到行星参数上检索了恒星参数。在这个九个候选人的样本中，我们通过统计验证（即，假阳性概率<$ 0.3 \％$）两个系统（TOI-277 B和TOI-1288 B），通过重新处理三脑候选者以及随访观察。这些新的经过验证的系外行星扩大了已知的热海王星人群，是对未来径向速度随访的高优先级目标。
We statistically validated a sample of hot Neptune candidates applying a two-step vetting technique using DAVE and TRICERATOPS. We performed a systematic validation of 250 transit-like events in the Transiting Exoplanet Survey Satellite (TESS) archive in the parameter region defined by $P\leq 4$ d and $3R_\oplus\leq R\leq 5R_\oplus$. Through our analysis, we identified 18 hot Neptune-sized candidates, with a false positive probability $<50\%$. Nine of these planet candidates still need to be confirmed. For each of the nine targets we retrieved the stellar parameters using ARIADNE and derived constraints on the planetary parameters by fitting the lightcurves with the juliet package. Within this sample of nine candidates, we statistically validated (i.e, with false positive probability < $0.3\%$) two systems (TOI-277 b and TOI-1288 b) by re-processing the candidates with TRICERATOPS along with follow-up observations. These new validated exoplanets expand the known hot Neptunes population and are high-priority targets for future radial velocities follow-up.
