On the colour- magnitude diagram they are situated near and more left than the hotter edge of the Cepheid instability stripe, so their temperature is higher than other types of pulsating variables.
在色星等图上，处于造父不稳定带的左外侧而温度较高，故简称热造父变星。 cnki
That would be enough to heat the core slightly and this heating would, in turn, accelerate the Cepheid's pulse rate.
这将足轻微加热内核，这种热量会反过来会加快造父变星的脉搏频率。 www.youfind.com.cn
They discovered almost800 Cepheid variable stars, a special class of pulsating star used for accurate distance measurement.
他们发现了差不多800个造父变星，一种用于准确测量距离的特殊变星。 www.astronomy.com.cn
This was accomplished by observing Cepheid variables at optical wavelengths out to greater distances than obtained previously and comparing those to similar measurements from ground-based telescopes.
这是通过观测比先前远得多的造父变星的可见光谱实现的，结果与地面望远镜观测结论类似。 www.astronomy.com.cn
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 pulsati on.
只要恰当地控制粒子束的照射时间，该恒星将有效地成为一台调频电台——以“造父变星”的脉冲为基础载波向宇宙广播。 ecocn
