中透镜探测邻近质量：从行星到黑洞
Mesolensing Explorations of Nearby Masses: From Planets to Black Holes
摘要：
附近的质量可以有一个很高的概率透镜恒星在遥远的背景领域。因此，高概率透镜或中透镜可以用来极大地增加我们对太阳附近黑暗和昏暗物体的了解，在那里它可以发现和研究当地黑暗群体的成员（自由漂浮的行星，低质量的矮星，白矮星，中子星和恒星质量的黑洞）。我们可以测量那些发现的（或已知的）天体的质量和横向速度，并确定它们是否是有暗淡伴星的双星。我们探索这些和其他应用mesolensing，包括已假设但未发现的物质形式的研究，如中等质量的黑洞，暗物质对象自由流动通过银河系盘，和行星在太阳系的最外层区域。在每一种情况下，我们讨论了基于当今的监测系统得出结果的可行性，并考虑了全景巡天望远镜和快速响应系统（Pan-STARRS）和大型综合巡天望远镜（LSST）时代的全天空监测的前景。
英文摘要：
Nearby masses can have a high probability of lensing stars in a distant background field. High-probability lensing, or mesolensing, can therefore be used to dramatically increase our knowledge of dark and dim objects in the solar neighborhood, where it can discover and study members of the local dark population (free-floating planets, low-mass dwarfs, white dwarfs, neutron stars, and stellar mass black holes). We can measure the mass and transverse velocity of those objects discovered (or already known), and determine whether or not they are in binaries with dim companions. We explore these and other applications of mesolensing, including the study of forms of matter that have been hypothesized but not discovered, such as intermediate-mass black holes, dark matter objects free-streaming through the Galactic disk, and planets in the outermost regions of the solar system. In each case we discuss the feasibility of deriving results based on present-day monitoring systems, and also consider the vistas that will open with the advent of all-sky monitoring in the era of the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS), and the Large Synoptic Survey Telescope (LSST).
