论文摘要
迄今为止，已经发现了成千上万的过渡系外行星，这在很大程度上要归功于{\ em kepler}太空任务。就像在所有人群中一样，当然对于系外行星，人们找到了具有独特特征的独特对象。在这里，我们将描述过去几年中发现的一小部分“分解”系外行星的特性和行为（KIC 12557548B，K2-22B等）。他们蒸发，失去大量裸露的核心，产生壮观的尘土飞扬的彗星状尾巴，并具有高度可变的不对称转移。除了这些系外行星外，还有观察性证据表明，甚至较小的``exo''对象绕着其他恒星：外囊式素和外果皮组。这些物体很可能也在Boyajian明星的奥秘背后。 {\ em tess}和柏拉图等持续的和即将到来的太空任务将有望发现更多这种物体，并且探索小型外露外系统身体的新时代将会浮出水面。
Thousands of transiting exoplanets have been discovered to date, thanks in great part to the {\em Kepler} space mission. As in all populations, and certainly in the case of exoplanets, one finds unique objects with distinct characteristics. Here we will describe the properties and behaviour of a small group of `disintegrating' exoplanets discovered over the last few years (KIC 12557548b, K2-22b, and others). They evaporate, lose mass unraveling their naked cores, produce spectacular dusty comet-like tails, and feature highly variable asymmetric transits. Apart from these exoplanets, there is observational evidence for even smaller `exo-'objects orbiting other stars: exoasteroids and exocomets. Most probably, such objects are also behind the mystery of Boyajian's star. Ongoing and upcoming space missions such as {\em TESS} and PLATO will hopefully discover more objects of this kind, and a new era of the exploration of small extrasolar systems bodies will be upon us.
