Hydrogenated Amorphous Carbon Grains As An Alternative Carrier Of The 9−13μm Plateau Feature In The Fullerene Planetary Nebula Tc 1
Fullerenes have been observed in several astronomical objects since the discovery of C60 in the mid-infrared (mid-IR) spectrum of the planetary nebula (PN) Tc 1. It has been suggested that […]

Cosmic Dust Fertilization Of Glacial Prebiotic Chemistry On Early Earth
Earth’s surface is deficient in available forms of many elements considered limiting for prebiotic chemistry. In contrast, many extraterrestrial rocky objects are rich in these same elements. Limiting prebiotic ingredients […]

The Possibility Of Panspermia In The Deep Cosmos By Means Of The Planetary Dust Grains
By obtaining the assumption that planetary dust particles can escape from the gravitational attraction of a planet, we consider the possibility for the dust grains to leave the star’s system […]
