“microlensing”的概念、定义、翻译、参考文献-科学参考

microlensing

Physics

The same type of lens effect that occurs in a gravitational lens but on a smaller scale, as caused by individual stars or small dark objects. In microlensing, the bending of light from a more distant star is too small to be detected but a change in the brightness of light from the distant star can be detected.

Astronomy

A small-scale gravitational lens effect. In microlensing, the gravitational field of the lensing object is not strong enough to form distinct images of the background source; instead, it causes an apparent brightening of the source. Stars are expected to vary in brightness in a characteristic manner if low-mass stars or planets pass in front of them, and this effect has been detected for stars in the Large Magellanic Cloud and in the central bulge of our Galaxy.
