您要查找的是不是：
- white dwarf branch 白矮星支
- It is then referred to as a White Dwarf. 这时，它被称为白矮星。
- Each white dwarf is a burned up, dying star like the sun. 每个白矮星都是类似于太阳燃烬后残存的恒星，
- A white dwarf is the inert remnant of what used to be a sunlike star. 白矮星是类似太阳的恒星在死亡后所留下恒久不变的残骸。
- As the white dwarf spins, the columns of infalling gas rotate with it. 当白矮星自转时，被吸入的气柱也跟著一起转起来。
- Since a 7-solar-mass is too large to be a white dwarf or neutron star,it must be a black hole. 因为有着7个太阳质量的星体不可能是白矮星或中于星，所以它一定是黑洞。
- The researchers suggest that there are many white dwarf stars throughout this halo. 研究人员猜想，光晕内到处有白矮星。
- It will quietly and steadily burn the hydrogen to helium and become a white dwarf. 它会稳定地把氢转化为氦,然后安静的死去,成为白矮星。
- The nova phenomenon generally occurs in a binary system that has as one member a very hot white dwarf. 新星这种现象一般发生在双星系统中，其中一颗子星是非常热的白矮星。
- Recall that Type I supernova is the strong explosion of a nova that even the white dwarf is destroyed. 还记得I型超新星是足以令中心白矮星炸毁的新星爆发吗?
- It would take only an hour for the white dwarf to smash through, but the damage would be irreversible. 白矮星只需要一个小时就可以猛穿而过，但其所造成的破坏是无法挽回的。
- Since a 7-solar-mass is too large to be a white dwarf or neutron star, it must be a black hole. 因为有着7个太阳质量的星体不可能是白矮星或中于星，所以它一定是黑洞。
- Except for an anomalously high surface abundance of nitrogen, the white dwarf should appear unchanged. 除非表面含氮量异常之高，白矮星应该不会显出变化。
- Leaves alternate, solitary, or fascicular on dwarf branches, sessile, linear, semiterete. 叶互生，单生，或束状在矮小的分枝，无梗的，线形，半圆柱形。
- Data from the Chandra observation show that the central ten-million-degree Celsius cloud is the remains of a supernova explosion that destroyed a white dwarf star. 来自钱德拉的观测数据表明，中心温度达上千万摄氏度的云湍团是超新星爆发的残余，爆发摧毁了一颗白矮星。
- Novae occur in double star systems comprising a white dwarf - the end product of a solar-like star - and, generally, a low-mass normal star - a red dwarf. 双星系统中包含一个白矮星（类似太阳的恒星的最终演化产品）和一个红矮星（一种低质量的普通星球）。
- Every 20 years or so, the red giant star dumps enough hydrogen gas onto its companion white dwarf star to set off a brilliant thermonuclear explosion on the white dwarf's surface. 大约每过20年，红巨星向它的白矮伴星上输出足够的氢气，在白矮星表面产生一次耀眼的热核爆炸。
- If the mass of the white dwarf becomes greater than about 1.4 times the mass of the Sun, it becomes unstable and is blown apart in a thermonuclear explosion. 如果白矮星的质量超过了太阳的1.;4倍，它会变得不稳定，并在热核爆炸中碎裂。
- The remnant central stellar core, destined to become a white dwarf star, glows in light so energetic it causes the previously expelled gas to fluoresce. 中央残留的恒星核注定会变成一颗白矮星，发出强光，使得先前喷出的气体发出荧光。
- Although white dwarf cosmochronology is still in its infancy, it already shows its potential as a powerful tool for estimating the ages of the various objects. 白矮星宇宙纪年学是一个很新的研究领域，但它已经在确定天体年龄方面显示出很大的潜力。
