The -dependence of transition frequencies for ions Si II, Cr II, Fe II, Ni II, and Zn II

V. A. Dzuba, V. V. Flambaum, M. G. Kozlov +1

We performed accurate calculation of -dependence () of the transition frequencies for ions, which are used in a search for the variation of the fine structure constant…

Series Expansions for Variable Electron Density

Zheng Weihong, C. J. Hamer, J. Oitmaa +1

We have developed a series expansion method for calculating the zero-temperature properties of lattice electron models for variable electron density, i.e. for finite doping away fr…

Shocked molecular gas towards the SNR G359.1-0.5 and the Snake

J. S. Lazendic, M. Wardle, M. G. Burton +4

We have found a bar of shocked molecular hydrogen (H2) towards the OH(1720 MHz) maser located at the projected intersection of supernova remnant (SNR) G359.1-0.5 and the nonthermal…

Stepwise structure of Lyapunov spectra for many particle systems by a random matrix dynamics

Tooru Taniguchi, Gary P. Morriss

The structure of Lyapunov spectra for many particle systems with a random interaction between the particles is discussed. The dynamics of the tangent space is expressed as a master…

ECHA J0843.3-7905: Discovery of an 'old' classical T Tauri star in the eta Chamaeleontis cluster

Warrick A. Lawson, Lisa A. Crause, Eric E. Mamajek +1

A limited-area survey of the eta Chamaeleontis cluster has identified 2 new late-type members. The more significant of these is ECHA J0843.3-7905 (= IRAS F08450-7854), a slowly-rot…

Formation Pumping of Molecular Hydrogen in the Messier 17 Photodissociation Region

M. G. Burton, D. Londish, P. W. J. L. Brand

We have imaged the emission from the near-infrared v=1-0 S(1), 1-0 S(7), 2-1 S(1) and 6-4 O(3) lines of molecular hydrogen in the N- and SW-Bars of M17, together with the hydrogen…
