Magnetar
词性: 名词

定义:
Magnetar(磁星)是一种极其特殊的中子星,其磁场比普通中子星强得多,强度可达到地球磁场的10亿倍以上。由于这种强大的磁场,magnetar 常常会产生剧烈的高能辐射,比如伽马射线爆发和X射线喷发。它是宇宙中已知最强的磁场源之一。

音标:
/ˈmæɡ.nɪ.tɑːr/

翻译:
磁星

用法:
Magnetar 通常被用来描述天文学中的一种天体,尤其是在描述具有超强磁场的中子星时。

例句:

The magnetar emitted a burst of gamma rays that could be detected across light years.
这颗磁星发出了伽马射线爆发,光年之外都能探测到。

Magnetars are believed to be responsible for some of the most intense gamma-ray bursts observed in the universe.
磁星被认为是一些最强伽马射线爆发的源头。

Scientists are studying magnetars to understand more about the behavior of matter under extreme magnetic fields.
科学家们正在研究磁星,以更好地理解物质在极端磁场下的行为。

The magnetic field of a magnetar is so strong that it could potentially distort the structure of nearby stars.
磁星的磁场如此强大,以至于它可能扭曲附近星体的结构。

Unlike regular neutron stars, magnetars can produce powerful bursts of X-rays and gamma rays.
与普通的中子星不同,磁星能产生强烈的X射线和伽马射线爆发。

The sudden burst of energy from a magnetar can be detected by telescopes even on Earth.
来自磁星的能量突发即使在地球上也能被望远镜探测到。

Researchers have theorized that the magnetic field of a magnetar could collapse, leading to an explosion.
研究人员理论上认为,磁星的磁场可能会坍塌,导致爆炸。

Magnetars are formed when a massive star collapses in a supernova explosion and the core becomes a neutron star with an incredibly strong magnetic field.
磁星是由大质量恒星在超新星爆炸时塌缩形成的,核心变成了拥有极其强大磁场的中子星。

The discovery of magnetars has provided new insights into the physics of neutron stars.
磁星的发现为我们提供了关于中子星物理的新见解。

Observing a magnetar’s magnetic field is a challenge for astronomers due to its complexity and power.
由于磁星磁场的复杂性和强大程度,天文学家观察磁星的磁场是一项挑战。

短语搭配:

magnetar flare (磁星闪光)

magnetar burst (磁星爆发)

magnetic field of a magnetar (磁星的磁场)

X-ray emission from a magnetar (来自磁星的X射线辐射)

gamma-ray burst from a magnetar (来自磁星的伽马射线爆发)

相关概念:

中子星 (Neutron Star): 一种由超新星爆炸后的核心坍缩形成的天体,其密度极高,质量通常是太阳的1.4倍左右。

伽马射线爆发 (Gamma-ray Burst): 宇宙中最强烈的高能辐射现象,可能由磁星、黑洞或超新星引发。
