quasar

类星体

Quasar

类星体或准恒星无线电源是称为活动星系核的一类物体中最有活力和遥远的成员。 类星体是非常明亮的,并且首先被认为是电磁能量的高红移源,包括无线电波和可见光,其似乎与星星相似,而不是与星系相似的延伸源。 它们的光谱包含非常宽的发射线,不同于从星星知道的,因此命名为“准恒星”。 它们的亮度可以是银河系的100倍。 虽然这些物体的性质直到20世纪80年代初是有争议的,但现在有一个科学的共识,类星体是一个紧凑的地区,在一个巨大的星系的中心,围绕着它的中心超大质量的黑洞。 它的大小是黑洞施瓦茨半径的10-10,000倍。 类星体发射的能量来源于质量下降到黑洞周围的吸积盘上。 Quasars or quasi-stellar radio sources are the most energetic and distant members of a class of objects called active galactic nuclei. Quasars are extremely luminous and were first identified as being high redshift sources of electromagnetic energy, including radio waves and visible light, that appeared to be similar to stars, rather than extended sources similar to galaxies. Their spectra contain very broad emission lines, unlike any known from stars, hence the name "quasi-stellar". Their luminosity can be 100 times greater than the Milky Way. While the nature of these objects was controversial until the early 1980s, there is now a scientific consensus that a quasar is a compact region in the center of a massive galaxy, that surrounds its central supermassive black hole. Its size is 10–10,000 times the Schwarzschild radius of the black hole. The energy emitted by a quasar derives from mass falling onto the accretion disc around the black hole.

在英语 词典里quasar的定义

字典中的类星体的定义是任何一类外星物体,它们从紧凑的光源发出大量的光,红外辐射等形式的能量。 它们非常遥远,它们的能量生成被认为是涉及位于星系中心的超大质量黑洞。

The definition of quasar in the dictionary is any of a class of extragalactic objects that emit an immense amount of energy in the form of light, infrared radiation, etc, from a compact source. They are extremely distant and their energy generation is thought to involve a supermassive black hole located in the centre of a galaxy.
