| dbo:abstract | - MOA-2009-BLG-387L is a red dwarf in the Sagittarius constellation that is host to the planet MOA-2009-BLG-387Lb. The star is estimated to be nearly 20,000 light years away and approximately one fifth the mass of the Sun, although large confidence intervals exist, reflecting the uncertainties in both the mass and distance. The star drew the attention of astronomers when it became the lens of gravitational microlensing event MOA-2009-BLG-387L, in which it eclipsed a background star and created distorted caustics, an envelope of reflected or refracted light rays. Analysis of the caustic events and of follow-up observational data led to the planet's discovery, which was reported in February 2011. (en)
- MOA-2009-BLG-387L est une étoile naine rouge de la constellation du Scorpion autour de laquelle orbite l'exoplanète MOA-2009-BLG-387L b. L'étoile se trouve à une distance estimée à environ 20 000 années-lumière de la Terre, et fait environ un cinquième de la taille du Soleil ; ces estimations sont faites avec un large intervalle de confiance, et comprennent donc une part d'incertitude.

- MOA-2009-BLG-387L是一颗位于人马座的红矮星，是系外行星MOA-2009-BLG-387Lb的母恒星。这颗恒星距离地球约20000光年，质量大约是太阳质量的1/5，但距离和质量并不完全确定，存在较大的置信区间。它因为在一次微引力透镜事件MOA-2009-BLG-387中成为透镜，遮掩和它刚好处于同一直线的背景星从而出现扭曲的而为天文学家所认识。对这次微引力透镜事件的研究和后续观测数据发现这颗恒星拥有行星，并在2011年2月正式公布。 (zh)
