摘要:

在本文中,我们观测到一颗1.8MJup的行星,它以538天的周期绕贫金属恒星HD 171028([Fe/H]=-0.49)运行。这颗行星是第一个在HARPS计划中发现的,该计划旨在寻找贫金属恒星周围的行星。有趣的是,HD 171028是样本中金属含量最低的恒星之一。这一发现被置于行星形成和演化模型的背景下。

英文摘要:

In this paper we present the detection of a 1.8 M_Jup planet in a 538 day period trajectory orbiting the metal-poor star HD171028 ([Fe/H]=-0.49). This planet is the first to be discovered in the context of a HARPS program searching for planets around metal-poor stars. Interestingly, HD171028 is one of the least metal-poor stars in the sample. This discovery is placed in the context of the models of planet formation and evolution.
