Does Magnetic Levitation or Suspension Define the Masses of Forming Stars?
Frank H. Shu, Zhi-Yun Li, Anthony Allen
We investigate whether magnetic tension can define the masses of forming stars by holding up the subcritical envelope of a molecular cloud that suffers gravitational collapse of it…
Correlated Hybrid Fluctuations from Inflation with Thermal Dissipation
Wolung Lee, Li-Zhi Fang
We investigate the primordial scalar perturbations in the thermal dissipative inflation where the radiation component (thermal bath) persists and the density fluctuations are therm…
Bound on the time variation of the fine structure constant driven by quintessence
Da-Shin Lee, Wolung Lee, Kin-Wang Ng
The bound on the time variation of the fine structure constant () driven by the dynamics of quintessence scalar field which is coupled to electromagnetism is discussed using phe…
Numerical Examination of the Stability of an Exact Two-dimensional Solution for Flux Pile-up Magnetic Reconnection
S. Hirose, Y. Litvinenko, S. Tanuma +9
The Kelvin--Helmholtz (KH) and tearing instabilities are likely to be important for the process of fast magnetic reconnection that is believed to explain the observed explosive ene…
A Search for Interstellar Pyrimidine
Yi-Jehng Kuan, Chi-Hung Yan, Steven B. Charnley +3
We have searched three hot molecular cores for submillimeter emission from the nucleic acid building-block pyrimidine. We obtain upper limits to the total pyrimidine (beam-averaged…
The energy spectrum of tau leptons induced by the high energy Earth-skimming neutrinos
J. -J. Tseng, T. -W. Yeh, H. Athar +3
We present a semi-analytic calculation of the tau-lepton flux emerging from the Earth, induced by the incident high energy neutrinos interacting inside the Earth for $10^{5} \leq E…
