Phosphorus-rich stars with unusual abundances are challenging theoretical predictions
T. Masseron, D. A. García-Hernández, R. Santoveña +4
Almost all chemical elements have been made by nucleosynthetic reactions in various kind of stars and have been accumulated along our cosmic history. Among those elements, the orig…
Petroleum, coal and other organics in space
F. Cataldo, D. A. Garcia-Hernandez, A. Manchado
The petroleum and coal models of the unidentified infrared emissions (UIE), sometimes referred also as unidentified infrared bands (UIBs) has been reviewed mainly based on the work…
Detection of CH, CH and H molecules in the Young Planetary Nebula IC 4997
N. Kameswara Rao, David L. Lambert, Arumalla B. S. Reddy +3
We have detected CH and CH molecular absorption lines from the young compact planetary nebula IC 4997 from high resolution optical spectra. A high-resolution infra-red (H and…
A Theoretical Investigation of the Possible Detection of C24 in Space
SeyedAbdolreza Sadjadi, Sun Kwok, Franco Cataldo +2
Astronomical infrared spectral features at ~6.6, 9.8 and 20 micronm have recently been suggested as being due to the planar graphene form of C24 carbon cluster. Here we report dens…
