X-rays breaking out of pre-explosion ejecta mark a supernova's first light
Weimin Yuan, Qiu-Ju Huang, Jin-Ping Zhu +130
Massive stars die as core-collapse supernovae, whose optical light emerges days after the implosion. Theory predicts that the initial collapse-driven shock, upon breaking through t…
Generalization of a localized-state formation mechanism in finite lattices with interaction nonlinearity
Huajie Song, Haitao Xu
We study how time-periodic, spatially localized states are born from the linear spectrum of a \emph{finite} lattice as the nonlinearity is switched on. In earlier work we treated t…
Unimolecular Chemical Kinetics in the Interstellar: Competition of Infrared Radiation and Collision Activation Mechanisms
Xiaorui Zhao, Rui Ming Zhang, Xuefei Xu +1
Unimolecular gas phase chemical reactions could be activated by both infrared (IR) radiation and inter-molecular collision in the interstellar environment. Understanding the interp…
High-Temperature Non-Equilibrium Atom-Diatom Collisional Energy Transfer
Xiaorui Zhao, Xuefei Xu, Haitao Xu
The change of the vibrational energy within a molecule after collisions with another molecule plays an essential role in the evolution of molecular internal energy distributions, w…
