adj. acetabuliform
天文学家发现一个碟状的尘埃围绕着一个巨型星体,该星体正在它的成长阶段,说明星体无论大小,形成的机制是一样的。
Astronomers have found a disk of dust around a huge, massive star in its early stages of growth, indicating that stars big and small form by the same mechanism.
但是它的规模大约是我们的太阳的20倍,而且环绕着一个碟状尘埃,尘埃的材料与成长中的小星体周围的碟状尘埃相似。
But it has a mass about 20 times that of our sun and is surrounded by a disk of material similar to what is found around smaller, growing stars.
它们‘清楚地显示了至少一些巨型恒星由环绕的碟状气体和尘埃凝聚而成,就如我们的太阳在45亿年前一样。’
They "clearly show that at least some massive stars grow by accreting material from a circumstellar disk of gas and dust, just like our sun did roughly 4.5 billion years ago."
