Evidence is reported for the first time for the presence of the Hg ii line in a Narval I profile of Maia, the fourth brightest member of the Pleiades open cluster. The Hg ii line in Maia absorbs about 2% of the local continuum and can be reproduced with an overabundance of mercury of about 4000 times the solar mercury abundance. This line is probably variable suggesting that mercury might be distributed in spot(s) over the surface of Maia. Maia is currently classified as a He-weak Mn star, it should probably be reclassified as a HgMn star.

在 Maia 的一个光谱中检测到 3983.93 Å 处的 Hg ii 谱线

首次报道了 在昴宿星疏散星团中第四亮的成员 Maia 的 Narval I 剖面中存在 Hg ii谱线的证据。Maia 中的 Hg  ii线吸收了约 2% 的局部连续谱，并且可以以大约 4000 倍于太阳汞丰度的过量汞进行复制。这条线可能是可变的，表明汞可能分布在 Maia 表面的斑点中。Maia 目前被归类为 He-weak Mn 星，它可能应该被重新归类为 HgMn 星。
