主序下部已发现系外行星及候选体的恒星:自转周期还是公转周期?

Stars of the Lower Part of the Main Sequence with Discovered Exoplanets and Candidates. Periods of Rotations or Revolutions?

Aleksey A. Shlyapnikov

AI总结:

本文通过将“太阳型活动恒星”星表与NASA系外行星档案交叉证认,统计了拥有系外行星的恒星在亮度、光谱型和光变幅度上的分布,并比较自转与公转周期,指出部分恒星的光变类型需重新判定。

摘要:

本工作的目的是为“太阳型活动恒星”星表补充已确认系外行星和系外行星候选体的信息。为此,对星表中的恒星与NASA系外行星档案数据进行了交叉证认。本文给出了疑似拥有系外行星的恒星数量按亮度、光谱型、光变幅度分布的情况,以及其他统计分析数据。特别关注了恒星自转周期与绕其运行的系外行星公转周期的比较。数据分析表明,有必要更改某些恒星先前确定的光变类型。

英文摘要:

The purpose of this work is to supplement the "Stars with solar-type activity" catalog with information about confirmed exoplanets and exoplanet candidates. To do this, cross-identification of the catalog stars with data from the NASA exoplanet archive was carried out. This article presents the distribution of the number of suspected stars with exoplanets by brightness, spectral type, amplitude of variability, as well as other statistical analysis data. Particular attention has been paid to the comparison of the periods of rotation of stars and the orbital periods of revolution of exoplanets around them. Analysis of the data suggests the need to change the previously determined types of variability in some stars.
