Adiabatic Perturbations in Homologous Conventional Polytropic Core Collapses of a Spherical Star
Yi Cao, Yu-Qing Lou
We perform a non-radial adiabatic perturbation analysis on homologous conventional polytropic stellar core collapses. The core collapse features a polytropic exponent relat…
Dark matter dominated dwarf disc galaxy Segue 1
Meng Xiang-Gruess, Yu-Qing Lou, Wolfgang J. Duschl
Several observations reveal that dwarf galaxy Segue 1 has a dark matter (DM) halo at least ~ 200 times more massive than its visible baryon mass of only ~ 103 solar masses. The bar…
Global Collapses and Expansions in Star-Forming Clouds
Yang Gao, Yu-Qing Lou
Spectral molecular line profile observations of star-forming molecular clouds sometimes show distinct red asymmetric double-peaked molecular line profiles with weaker blue peaks an…
Large-scale sidereal anisotropy of multi-TeV galactic cosmic rays and the heliosphere
M. Amenomori, X. J. Bi, D. Chen +83
We develop a model anisotropy best-fitting to the two-dimensional sky-map of multi-TeV galactic cosmic ray (GCR) intensity observed with the Tibet III air shower (AS) array. By inc…
Perturbation Analysis of a General Polytropic Homologously Collapsing Stellar Core
Yi Cao, Yu-Qing Lou
For dynamic background models of Goldreich & Weber and Lou & Cao, we examine 3-dimensional perturbation properties of oscillations and instabilities in a general polytropic homolog…
Molecular Line Profiles of Collapsing Gas Clouds
Yang Gao, Yu-Qing Lou, Kinwah Wu
Emission line profiles of tracer molecule HCO 140 GHz transition from gravitational core collapsing clouds in the dynamic process of forming protostars are calculated, using a…
