Measuring the Universe: The Cosmological Distance Ladder
Just as a pendulum clock eventually stops, a vibrating tuning fork falls silent, and
a child's swing comes to rest, so will a pulsating star rapidly stop pulsating. In
order to maintain the oscillations, energy must somehow be pumped into ...

Principles of Stellar Evolution and Nucleosynthesis
These average quantities are a function of mass, composition, and state of
nuclear evolution, and so they may change on time scales appropriate to the
nuclear evolution of the core of the pulsating star. But the attempt to understand
the ...

The Carbon
Star Phenomenon
This behavior is illustrated in Figure 1 for HIP 59844, the pulsating star BH Cru.
The ratio Q = Affp/Ay is around 0.7 for early type C and M giants. It shows a slight
decrease for the reddest stars (Figure 2). Large-amplitude periodic variables ...

Getting the Measure of the Stars
Suppose we mentally focus on a particular group of atoms making up a cubic
metre of material in the transition zone (see the insert in figure 6.3). In a non-
pulsating star it would remain at fixed radius, but in a pulsating star we must
follow the ...

Astrophysics is Easy!: An Introduction for the Amateur ...
You would be wrong, however, as the rate of nuclear fusion remains constant in a
pulsating star. Astronomers have realized that the variations are caused by
changes in the rate at which energy can escape from the star. The explanation is
...

Observing Variable Stars
Chapter. 4. Pulsating. Variable. Stars. Pulsating variables are stars showing
periodic expansion and contraction of their surface layers. The pulsations may be
radial or non-radial. A radially pulsating star remains spherical in shape, while in
...

Universe: The Solar System
Just as a bouncing ball eventually comes to rest, a pulsating star would soon stop
pulsating without something to keep its os- cillations going. In 1914, the British
astronomer Arthur Eddington suggested that a Cepheid pulsates because the ...
