Cometary outbursts are sporadic events whose mechanisms are not well known where the activity and consequently the brightness can increase hundreds of thousands of times within a few hours to several days. This indicates a dramatic departure from the

The interaction of radiation with matter is a fundamental process in the universe; in particular, the absorption and scattering of radiation by matter (the opacity) govern the formation, evolution, and structure of stars and planets. But opacity is

The largest solar system bodies that approach the Sun closely are comets. Some graze the solar photosphere and are called sungrazers. All of the sungrazing comets undergo disproportionate brightening just before their perihelion passage. This phenome

The extraordinary activity of comet C/1995 O1 (Hale-Bopp) made it possible to observe the emission bands of the radicals C2 and C3 in the optical wavelengths range at heliocentric distances larger than 3 AU. Based on these observations, we perform an

Asteroids and comets that are near the orbit of the Earth are commonly called near-Earth objects (NEOs), and there is some concern that Earth might be struck by such a body. If a body were discovered on a collision course with Earth, the issue of mit
