One question, Tan says, is how efficiently the process works for massive versus light stars, because that's likely to be the mechanism that determines stellar mass.
有个问题,谭说,在巨型与小恒星间,谁的形成机制更有效,因为那可能是确定星际物质形成机制。
The strength of the absorption features indicates that red dwarfs account for 80 percent of the number of stars in elliptical galaxies and 60 percent of the total stellar mass in those galaxies.
吸收特性的力度显示,红矮星数量约占椭圆星系星量的百分之八十,质量则是那些星系总质量的百分之六十。
This was based on the assumption that SMBHs form in a similar way to stellar-mass black holes, marking the final phase in the lifespan of massive stars that have exhausted all their fuel for fusion.
这是以大多超大质量黑洞形成过程与恒星质量的黑洞的形成过程类似的假设为基础的。 这种黑洞的形成通常在大质量恒星的生命过程的最终阶段(用尽了用于核聚变的所有燃料的时期)。
This means that the lowest mass black holes may be very rare, short-lived or non-existent, creating a conspicuous gap between the most massive neutron stars and the least massive stellar black holes.
也就是说,那些最小的黑洞恐怕真是转瞬即逝或者压根就没存在过。这使得最大的中子星与由最小质量恒星产生的黑洞间存在巨大的差距。
A low mass X-ray binary (LMXB) is a celestial system in which a relatively normal star is being eaten alive by a nearby stellar corpse, either a neutron star or a black hole.
低质量X射线双星(LMXB)是一颗相对正常的恒星和邻近的正在对其进行蚕食的恒星“遗体”构成的天体系统,“遗体”是中子星或黑洞。
If the magnetic stress bears up the gravitation in the stellar evolution, the big mass neutron star over the neutron - star mass can not collapse into a black hole.
如果在恒星演化过程有磁应力来支撑引力,超过中子星质量上限的大质量中子星则不致于坍缩成黑洞。
Brown dwarf star is a class of stellar objects as a mass of about 5-90 Jupiter.
棕矮星是类恒星天体的一种,质量约为5至90个木星之间。
The uncertainties associated with current stellar models lie in the input physics: atomicdata, convection theory, mixing in radiative regions, and mass loss.
当前恒星模型中的不确定性来自于输入的物理参数:原子数据、对流理论、辐射区的混合和质量丢失。
Observational evidence for stellar winds obtained from radio, infrared, visible, UV and X-ray regions are given. And two important parameters, terminal velocity and mass loss rate, are discussed.
在观测方面,给出了从射电、红外,可见光、紫外和X射线各波段得到的观测证据,并介绍了星风的两个重要参数、星风的终速和质量损失率。
A stellar system consisting of two stars orbiting about a common center of mASs and often appearing AS a single visual or telescopic object.
由两颗围绕一个共同的中心运行的星组成的星系,经常可用肉眼观看或用望远镜可观察到。
