接下来，恒星被慢慢拉伸（画面中间的黄色部分），最终被撕扯为碎片，回旋着进入黑洞（画面右侧的云环）。

The star then stretches apart (middle yellow blob) and eventually breaks into stellar crumbs, some of which swirl into the black hole (cloudy ring at right).

天文学家推测该环的表面年龄大约在5000年左右，还发现垂直于该环形行星有着距离更远的气体云，图中就是左上和右下的部分。

Astronomers estimating the apparent age of the ring to be around 5, 000 years, also find more distant gas clouds perpendicular to the ring plane, seen here at the upper left and lower right.

HOMO和LUMO上电子云主要集中在主链芴环上，侧链上几乎没有电子云分布，与其它轨道相比电子流动性较强。

The electronic clouds focus on the main chain fluorene units but none on side ones on both HOMO and LUMO.
