摘要:

我们打算编制最完整的β Picture协会的真实成员和候选成员的目录,并通过我们自己的观察,公共档案和探索文献来测量他们的旋转周期和基本属性。我们开展了一项多天文台活动,以获得我们自己的光度时间序列,并收集了我们目录中恒星的所有存档的公共光度数据时间序列。每个时间序列进行了分析与Lomb-Scargle和CLEAN周期图搜索恒星自转周期。我们补充了测量的旋转特性与详细的信息,多重性,成员资格,并预计在文献中的旋转速度,并讨论了明星明星。我们测量了117个成员中的112个的自转周期,并且尽可能地测量了恒星自转轴的光度、半径和倾角。这是迄今为止最大的年轻松散恒星协会的旋转周期目录。我们提供了一个广泛的目录旋转周期连同其他相关的基本属性有用的探索一些开放的问题,如传播的原因,旋转周期之间的同时代的恒星,角动量的演变,和锂旋转连接。

英文摘要:

We intended to compile the most complete catalog of bona fide members and candidate members of the beta Pictoris association, and to measure their rotation periods and basic properties from our own observations, public archives, and exploring the literature. We carried out a multi-observatories campaign to get our own photometric time series and collected all archived public photometric data time series for the stars in our catalog. Each time series was analyzed with the Lomb-Scargle and CLEAN periodograms to search for the stellar rotation periods. We complemented the measured rotational properties with detailed information on multiplicity, membership, and projected rotational velocity available in the literature and discussed star by star. We measured the rotation periods of 112 out of 117 among bona fide members and candidate members of the beta Pictoris association and, whenever possible, we also measured the luminosity, radius, and inclination of the stellar rotation axis. This represents to date the largest catalog of rotation periods of any young loose stellar association. We provided an extensive catalog of rotation periods together with other relevant basic properties useful to explore a number of open issues, such as the causes of spread of rotation periods among coeval stars, evolution of angular momentum, and lithium-rotation connection.
