摘要
在这项工作中,我们对John Flamsteed和Philippe de La Hire在蒙德极小期所做的太阳黑子测量、绘图和雕刻进行了广泛的回顾和详细的分析。展示了所有关于太阳黑子性质的现有信息和当代知识。重建了太阳黑子和太阳黑子群的坐标、面积和数量。基于这些观察,拉哈尔、让-多米尼克·卡西尼和他的儿子雅克·卡西尼定期发表结果,阐明太阳黑子测量的目的和当时的科学范式。特别是,天文学家认为太阳黑子在过去几十年里是周期性的。我们将重建的时间-纬度图与sperer (Ueber die periodicitat der sonnenflecken seit dem Jahre 1618)得到的时间-纬度图进行了比较。, 1889)和Ribes and Nesme-Ribes (Astron。天体物理学。276,549,1993)。估计了恒星微分自转速率,重建了其纬向剖面。我们还评估了遵守或违反乔伊定律的太阳黑子群的比例。
Sunspot Observations in 1684 – 1702: John Flamsteed and Philippe de La Hire
In this work, we present an extensive review and detailed analysis of sunspot measurements, drawings, and engravings made by John Flamsteed and, mainly, by Philippe de La Hire during the Maunder minimum. All available information and contemporary knowledge about the sunspot nature are shown. The coordinates, areas, and numbers of sunspots and sunspot groups are reconstructed. Based on these observations, La Hire, Jean-Dominique Cassini, and his son Jacques Cassini regularly published results that shed light on the purpose of sunspot measurements and the scientific paradigm of that time. In particular, astronomers believed that sunspots were recurrent over decades. We compare the reconstructed time-latitude diagram with those obtained by Spoerer (Ueber die periodicitat der sonnenflecken seit dem Jahre 1618..., 1889) and Ribes and Nesme-Ribes (Astron. Astrophys.276, 549, 1993). The sidereal differential rotation rate is estimated, and its latitudinal profile is reconstructed. We also evaluate the fraction of sunspot groups that obey or violate Joy’s law.
期刊介绍:
Solar Physics was founded in 1967 and is the principal journal for the publication of the results of fundamental research on the Sun. The journal treats all aspects of solar physics, ranging from the internal structure of the Sun and its evolution to the outer corona and solar wind in interplanetary space. Papers on solar-terrestrial physics and on stellar research are also published when their results have a direct bearing on our understanding of the Sun.
