AN INTERSTELLAR CLOUD WITH A HIGH CON- CENTRATION OF CN MOLECULES Gurno
ثبت نشده
چکیده
A group of stars embedded in an emission nebula near the cluster NGC 7822 has been discovered to have a unique interstellar spectrum, characterized by exceedingly strong CN lines. Evidence is presented favoring the hypothesis that the CN molecules arise in the immediate neighborhood of the H 11 region boundary. It is further suggested that the CN molecules are formed in the solid particles of the Hr region when fl.ashed by the UV radiation in the advancing ionization front.

L etter to the E ditor Interstellar atoms , molecules and diffuse bands toward SN 2006 X in M 100 ⋆
Aims. Supernovae offer the unique possibility to probe diffuse extra-galactic sightlines via observation of the optical transitions of atoms, molecules and the diffuse interstellar bands (DIBs). Through optical spectroscopy the presence of (complex) molecules in distant galaxies can be established and used to derive local physical conditions of the interstellar medium (ISM). Methods. High resol...
متن کاملInvestigation on the reaction of Iranian oriental and semi oriental tobacco genotypes to Potato Virus Y (PVY) under controlled conditions
Potato virus Y (PVY) as one of the serious diseases on tobacco (Nicotiana tabacum L.), reduces leaf yield and its quality. Use of re-sistant genotypes is being considered as the most effective, economical and a safe way to reduce damages of the virus. In the present study, the response of 90 oriental and semi-oriental tobacco genotypes was evaluated against PVY using randomized complete block d...
متن کاملMolecular abundances in the Magellanic Clouds III. LIRS 36, a star-forming region in the Small Magellanic Cloud?
Detections of CO, CS, SO, C2H,HCO, HCN,HNC, H2CO, and C3H2 are reported from LIRS 36, a star-forming region in the Small Magellanic Cloud. C18O, NO, CH3OH, and most notably CN have not been detected, while the rare isotopes 13CO and, tentatively, C34S are seen. This is so far the most extensive molecular multiline study of an interstellar medium with a heavy element depletion exceeding a factor...
متن کاملCumulenic and heterocumulenic anions: potential interstellar species?
A recent theoretical investigation by Terzieva & Herbst of linear carbon chains, Cn where n ≥ 6, in the interstellar medium has shown that these species can undergo efficient radiative association to form the corresponding anions. An experimental study by Barckholtz, Snow & Bierbaumof these anions has demonstrated that they do not react efficiently with molecular hydrogen, leading to the possib...
متن کاملInterstellar absorption lines toward Cep OB4
An analysis of optical echelle spectra towards nine stars in the Cep OB4 association is presented. Interstellar absorption lines which arise in the (1, 0) and (2, 0) bands of the CN A 2Π – X 2Σ+ red system towards BD+66◦ 1661, BD+66◦ 1674, and BD+66◦ 1675 are used to infer accurate CN column densities N(CN). A comparison with earlier measurements in the CN violet system allows to infer a CN Dop...
