旋星体 [
xuán xīng tǐ]
[无脊椎] spiraster
- 这个模型解释了旋臂中和旋臂附近星体的形成。
This model also agrees with enhanced star formation in or near spiral arms; - 星体是绕着短轴自旋的,但它们也会同样地摆动。
Stars spin around or nearly around a short axis rather than a long axis, but they can wobble just the same. - 即使行星际的微流星体和猛烈的磁层离子体没把它们消灭,辐射的细微影响也会让小粒子迴旋掉下。
Even if they survive interplanetary micrometeoroids and fierce magnetospheric plasma, the subtle force exerted by radiation causes their orbits to spiral inward.
