This is sigma star with the antibonding orbital that came from 1s, and it is a molecular orbital.

这是sigma星，来自于1s的反键轨道，它是一个分子轨道。

So this is the 1 s star, sigma 1 s star orbital, and what you have in the center here is a node, right in the center between the two nuclei.

这是1s星，sigma1s星轨道，中间这个是节点，它在两个原子核中间。
