A cepheid 's distance can thus be calculated with great accuracy .
由此我们可以精确测量一颗造父变星的距离。
That would be enough to heat the core slightly and this heating would , in turn , accelerate the cepheid 's pulse rate .
这将足于稍微加热星核，而其温度上升将随之加速“造父变星”的脉动率。
Time the beam right and the star could be turned , in effect , into an fm transmitter-broadcasting to the universe on the underlying carrier-wave of the cepheid 's pulsation .
