WebIn fact, we see that all of the youngest stars in the sky live in regions with a lot of interstellar matter. It seems clear that there must be a connection between the stars and the interstellar gas. By observing these regions in many wavelengths of light, astronomers have found that new stars are formed out of the gas and dust in these clouds. WebBesides providing ~ 30% of the total Galactic luminosity via their IR emission, dust grains actively participate in the cycle of matter (gas and dust) from the interstellar medium (ISM) to stars and back from stars to the ISM: (1) solid grains condense in the cool atmospheres of evolved stars, Wolf-Rayet stars, planetary nebulae, and novae and supernovae ejecta, …
