Astrophysics is a branch of space science that applies the laws of physics and chemistry to seek to understand the universe and our place in it.
If the parameters of the Cepheid are in a certain “instability strip”, then the interaction of the kappa mechanism with the other mechanisms of stellar dynamics create a periodic oscillation in the Cepheid’s radius, which increases with the mass and brightness of the Cepheid.For a recent re...
The atmospheres of planets orbiting other stars (exoplanets) are windows into their chemical composition and physical properties. For a planet that orbits closely to its star, the intense stellar irradiation can induce substantial atmosp... M Brogi - 《Science》 被引量: 0发表: 2018年 加载更多...
Amateur and professional astrophotographers aim their telescopes and cameras toward the heavens to capture vivid, breathtaking shots of everything from nearby stellar neighbors to nebula too far to comprehend. As the study of space and photography techniques have progressed, observatories and orbiting ...
two different teams of astronomers observing far-offsupernovaenoticed that (at a certain redshift) the stellar explosions were dimmer than expected. These groups were led by astronomers Adam Riess, Saul Perlmutter, and Brian Schmidt. This trio won the 2011 Nobel Prize in Physics for this work....
