a pulsar is a celestial object that emits llight in short burst a pulsar in the crab nebula flashes at a rate of 30 times/s,suppose the light pulses are caused by the rotation of a spherical object that emits light from a pair of diametrically opposed "flashlights" on its equator. what is the maximum radius of the pulasae if no part of its surface can move faster than the speed of light?

A pulsar is a celestial object that emits light in short burst.
脉冲星是一种能够发出光脉冲的天体。

A pulsar in the crab nebula flashes at a rate of 30 times/s, suppose the light pulses are caused by the rotation of a spherical object that emits light from a pair of diametrically opposed "flashlights" on its equator.
1)一个在蟹状星云中的脉冲星的闪烁频率是每秒30次。
2)假定这些光脉冲是来自这个旋转着的球体的赤道上相对的两个“闪光灯”。

What is the maximum radius of the pulsar if no part of its surface can move faster than the speed of light?
3)如果这个脉冲星表面任何一部分的移动速度都不会超过光速

问:这个脉冲星的最大半径是多少?

脉冲星是一种以短脉冲形式放射光线的天体,一颗螃蟹星云内的脉冲星闪烁频率为每秒30次。据推测,其脉冲光线是由球状天体在旋转时于其赤道上放射相互直接对立的闪光造成的。如果说脉冲星的表面任何部分都不可能以超越光的速度运动,那么它的最大半径是多少?
