摘要

SWEET-Cat(带系外行星的恒星目录)最初于2013年推出,从那时起,已确认的系外行星数量显著增加。要全面了解这些新世界,关键的一步是对其宿主恒星进行精确而均匀的表征。在太阳系外行星百科全书和美国国家航空航天局系外行星档案中新发现系外行星之后,我们利用大量高分辨率光谱继续在 SWEET-Cat 中为行星宿主恒星添加新的恒星参数。我们获得了大量这些行星寄主恒星的高分辨率光谱,这些光谱有的是我们团队观测到的,有的是通过公共档案收集到的。对于 FGK 恒星,光谱恒星参数是按照与之前 SWEET-Cat 发布时相同的同质过程,利用 ARES+MOOG 对光谱进行推导得出的。将恒星特性与行星特性结合起来,研究可能存在的相关性,以便为恒星与行星的联系研究提供更多信息。我们将具有同质参数的恒星数量增加了232颗(从959颗增加到1191颗)。然后,我们把注意力集中在质量和半径都已确定的系外行星上,重新审视质量-半径关系,我们发现其结果与之前文献报道的结果一致。对于大质量行星,我们还重新审视了半径异常,证实了先前结果中已经暗示的半径异常与金属性的相关性。

SWEET-Cat: A view on the planetary mass-radius relation
SWEET-Cat (Stars With ExoplanETs Catalogue) was originally introduced in 2013, and since then, the number of confirmed exoplanets has increased significantly. A crucial step for a comprehensive understanding of these new worlds is the precise and homogeneous characterization of their host stars. We used a large number of high-resolution spectra to continue the addition of new stellar parameters for planet-host stars in SWEET-Cat following the new detection of exoplanets listed both at the Extrasolar Planets Encyclopedia and at the NASA exoplanet archive. We obtained high-resolution spectra for a significant number of these planet-host stars, either observed by our team or collected through public archives. For FGK stars, the spectroscopic stellar parameters were derived for the spectra following the same homogeneous process using ARES+MOOG as for the previous SWEET-Cat releases. The stellar properties are combined with the planet properties to study possible correlations that could shed more light into the star-planet connection studies. We increase the number of stars with homogeneous parameters by 232 ($\sim$ 25\% - from 959 to 1191). We then focus on the exoplanets with both mass and radius determined to review the mass-radius relation where we find consistent results with the ones previously reported in the literature. For the massive planets we also revisit the radius anomaly where we confirm a metallicity correlation for the radius anomaly already hinted in previous results.
