pulsating star

[′pəl‚sād·iŋ ′stär]
(astronomy)
Variable star whose luminosity fluctuates as the star expands and contracts; the variation in brightness is thought to come from the periodic change of radiant energy to gravitational energy and back.

These tend to have considerably larger amplitudes and longer periods than the other pulsating stars.
However, the study revealed hardly any pulsating stars around a region almost 1,000 light years wide from the core of the galaxy.
The primary goal of the EXOTIME project is to use the timing method to detect exoplanets around evolved pulsating stars such as subdwarf B (sdB) stars and white dwarfs.
Anthony Hewish and Jocelyn Bell make the most exciting recent observation in astrophysics by discovering pulsating stars or `pulsars' using Cambridge's Mullard Radio Astronomy Observatory.
The structure remains the third largest steerable telescope in the world and plays a key role in global research on pulsating stars, testing extreme physics theories including Einstein's general theory of relativity.
Yellowish, pulsating stars known as Cepheid variables remain the favorite, and many say the most credible, standard candle for estimating the distance to relatively nearby galaxies.
This process is simple in orderly, highly regular pulsating stars such as Cepheids and RR Lyraes.
This galaxy is of further interest to astronomers because its relative proximity allows them to study a wide range of astronomical objects within it, including stellar nurseries, dust clouds, and pulsating stars called Cepheid variables, which astronomers use as distance markers in the Universe [2].
Delta is the prototype of a class of pulsating stars known as Cepheid variables.
Past student projects have included observing and modeling eclipsing binary stars and cataclysmic variables, monitoring comets and blazars for outbursts and other changes, and computing simulations of fluid instabilities, pulsating stars, and spiral patterns in galaxies.
The first rung consists of pulsating stars called Cepheid variables, or Cepheids for short.
