On the non-thermal kappa-distributed electrons in planetary nebulae and HII regions: the kappa index and its correlations with other nebular properties
Yong Zhang, Bing Zhang, Xiao-Wei Liu
Recently, a suspicion arose that the free electrons in planetary nebulae (PNe) and HII regions might have non-thermal energy distributions. In this scenario, a kappa index is intro…
Methanol Observation of IRAS 19312+1950: A Possible New Type of Class I Methanol Masers
Jun-ichi Nakashima, Andrej M. Sobolev, Svetlana V. Salii +3
We report the result of a systematic methanol observation toward IRAS 19312+1950. The properties of the SiO, H2O and OH masers of this object are consistent with those of mass-losi…
A Theoretical Study on the Vibrational Spectra of PAH Molecules with Aliphatic Sidegroups
SeyedAbdolreza Sadjadi, Yong Zhang, Sun Kwok
The role of aliphatic side groups on the formation of astronomical unidentified infrared emission (UIE) features is investigated by applying the density functional theory (DFT) to…
