论文摘要
我们介绍了从WASP 186B和WASP-187B（TOI-1494.01和TOI-1493.01）中发现的两个新的热木星。它们的行星性质是从索菲光谱观测中确定的，并从苔丝获得了其他光度法。宿主星的恒星参数源自光谱线，IRFM和等环位置分析。这些参数与MCMC方法中的光度和径向速度数据结合使用，以确定行星特性。 WASP-186B是巨大的木星（4.22 +/- 0.18 m_j，1.11 +/- 0.03 r_j），在5.03天偏心（e = 0.327 +/- 0.008）轨道上绕中-F恒星旋转。 WASP-187b是一个低密度（0.80 +/- 0.09 m_j，1.64 +/- 0.05 R_J）行星，在围绕早期F型恒星稍微演变的5.15天圆轨道上。
We present the discovery of two new hot Jupiters identified from the WASP survey, WASP-186b and WASP-187b (TOI-1494.01 and TOI-1493.01). Their planetary nature was established from SOPHIE spectroscopic observations, and additional photometry was obtained from TESS. Stellar parameters for the host stars are derived from spectral line, IRFM, and isochrone placement analyses. These parameters are combined with the photometric and radial velocity data in an MCMC method to determine the planetary properties. WASP-186b is a massive Jupiter (4.22 +/- 0.18 M_J, 1.11 +/-0.03 R_J) orbiting a mid-F star on a 5.03 day eccentric (e=0.327 +/- 0.008) orbit. WASP-187b is a low density (0.80 +/- 0.09 M_J, 1.64 +/- 0.05 R_J) planet in a 5.15 day circular orbit around a slightly evolved early F-type star.
