Period-mass-loss rate relation of Miras

We report the discovery that Mira variables with and without absorption lines of the element technetium (Tc) occupy two different regions in a diagram of near- to mid-IR colour...我们在此报道一项发现：带有与不带元素锝（technetium, Tc）吸收线的米拉变星（Mira variables），在近红外至中红外（near- to mid-IR）颜色的分布图中，分别占据两个不同的区域。
