Asteroseismology and Interferometry
摘要:
天文地震学为我们提供了一个独特的机会,以提高我们对恒星结构和演化的理解。最近的发展,包括第一次系统的研究类太阳辐射,提高了这一领域的研究在天体物理学的影响,并导致了显着增加的规模研究界。在本论文中,我们首先回顾了经典和类太阳恒星的基本观测和理论性质,并介绍了这些恒星的一些最新和杰出的研究结果。我们集中我们的审查,干涉研究,预计将提供一个显着的输入这些类的reflectators。我们讨论了目前的限制,asteroseismic的研究,包括模式识别和脉动星的全球参数的准确测定的困难,并在简要回顾了这些方面的干涉测量是最相关的,在这种情况下,预计如何干涉观测可能有助于克服这些限制。此外,我们目前的脉动恒星涉及两个asteroseisic和干涉仪的限制,并展望未来,总结正在进行的努力,有关未来的仪器和卫星任务的发展,预计将在这一领域的研究产生影响的最新试点研究结果。
英文摘要:
Asteroseismology provides us with a unique opportunity to improve our understanding of stellar structure and evolution. Recent developments, including the first systematic studies of solar-like pulsators, have boosted the impact of this field of research within Astrophysics and have led to a significant increase in the size of the research community. In the present paper we start by reviewing the basic observational and theoretical properties of classical and solar-like pulsators and present results from some of the most recent and outstanding studies of these stars. We centre our review on those classes of pulsators for which interferometric studies are expected to provide a significant input. We discuss current limitations to asteroseismic studies, including difficulties in mode identification and in the accurate determination of global parameters of pulsating stars, and, after a brief review of those aspects of interferometry that are most relevant in this context, anticipate how interferometric observations may contribute to overcome these limitations. Moreover, we present results of recent pilot studies of pulsating stars involving both asteroseismic and interferometric constraints and look into the future, summarizing ongoing efforts concerning the development of future instruments and satellite missions which are expected to have an impact in this field of research.
