1.25 Over the past 40 years, about 140 distinct molecular species have been detected in a wide range of astronomical locations (see http://www.cv.nrao.edu/~awootten/ allmols.html). We now know that molecules are present within our galaxy in the atmospheres of cool stars, in stellar envelopes, in planetary nebulae, in the ejecta of novae and supernovae, in diffuse and dense clouds in the interst...
متن کاملZeeman splitting in interstellar molecules
The Zeeman splitting that a longitudinal magnetic field would produce on the ethynyl radical is calculated for the transitions typical of those observed in the interstellar clouds. It turns out that the ubiquitous CCH radical adds to the list of the few interstellar molecules that could be used to determine magnetic fields in molecular clouds.
متن کاملCharacterization of Interstellar Organic Molecules
Understanding the origins of life has been one of the greatest dreams throughout history. It is now known that star-forming regions contain complex organic molecules, known as Polycyclic Aromatic Hydrocarbons (PAHs), each of which has particular infrared spectral characteristics. By understanding which PAH species are found in specific star-forming regions, we can better understand the biochemi...
متن کاملConsiderations regarding Ontology Design Patterns
The Worskhop on Ontology and Semantic Web Patterns (WOP2015, 6th edition) was held on October 11, 2015 in conjunction with the 14th International Semantic Web Conference in Bethlehem, PA, USA. At the workshop, the organizers conducted a discussion with the participants regarding the promises and obstacles of ontology design patterns (ODPs for short). This editorial reports on those discussions....
متن کاملAdsorption of Astrochemically Relevant Molecules on Interstellar
In the last few decades, astronomers have found that interstellar clouds are chemical factories, in which atoms are processed into more complex chemical species in reactions energized by starlight and fast particles. Many of the identified molecules are formed in networks of ion-molecule and neutral-neutral reactions and, at the low temperatures in the interstellar medium (-15 K), can accrete o...
