WebIdentify the physical characteristics of stars that are used to create an H–R diagram, and describe how those characteristics vary among groups of stars; Discuss the physical … WebRecently spectral types L and T have been proposed for the very coolest and faintest stars that have been discovered. Type L stars have temperatures between 1,300 and 2,000K; their spectra show absorption by iron hydride (FeH) and chromium hydride (CrH) molecules. Even cooler objects, temperatures between 700 and 1,300K and that show strong ...

WebApr 17, 2024 · Stars are massive objects that have a large gravitational field, which drives the star to contract on itself, which is why fusion occurs: in the center of the star the nuclei of atoms are already so close due to gravity and high temperatures that bind. This is what is called nuclear fusion and is the energy source of a star. On the other hand ...

WebIn this work, we shortly review the role and properties of hyperons in finite and infinite nuclear systems such as hypernuclei and neutron stars. Particularly, we describe different production mechanisms of hypernuclei, discuss some aspects of their γ-ray spectroscopy and their weak decay modes, and give a few strokes on their theoretical description.
