Circumstellar gas and dust emission and mass loss from evolved stars
Orbiting a star Gas Dust emissions Evolution of stars
2014/12/9
This dissertation presents a study of the circumstellar gas and dust emission and their relation to the mass-loss in evolved stars. Considering the physical process of heating and cooling of the dust,...
The Gas Properties of the W3 GMC: A HARP study
ISM Westerhout 3 submillimetre HARP study Gas Properties
2012/2/23
We present 12CO, 13CO and C18O J=3-2 maps of the W3 GMC made at the James Clerk Maxwell Telescope. We combine these observations with Five Colleges Radio Astronomy Observatory CO J=1-0 data to produce...
3 to 12 millimetre studies of dense gas towards the western rim of supernova remnant RX J1713.7-3946
12 millimetre dense gas the western rim supernova remnant RX J1713.7-3946
2012/2/23
The young X-ray and gamma-ray-bright supernova remnant RXJ1713.7-3946 (SNR G347.3-0.5) is believed to be associated with molecular cores that lie within regions of the most intense TeV emission. Using...
Gas density and star formation in the rarified regions of discs of normal and LSB galaxies
Gas density star formation rarified regions discs normal
2011/10/11
We calculated the radial profiles of the azimuthally averaged midplane gas volume density $\rho_g$ for 11 high surface brightness (HSB) spiral galaxies, 7 low surface brightness (LSB) galaxies and 3 S...
The Cold Gas Content of Bulgeless Dwarf Galaxies
galaxies: dwarf– galaxies: evolution – galaxies: formation – methods:N-body simulations
2011/10/9
We present an analysis of the neutral hydrogen (HI) properties of a fully cosmological hydrodynamical dwarf galaxy, run with varying simulation parameters. As reported by Governato et al. (2010), the ...
The State of the Gas and the Relation Between Gas and Star Formation at Low Metallicity: the Small Magellanic Cloud
State Relation Between Gas Star Formation Metallicity: Magellanic Cloud
2011/9/30
We compare atomic gas, molecular gas, and the recent star formation rate (SFR) inferred from H-alpha in the Small Magellanic Cloud (SMC). By using infrared dust emission and local dust-to-gas ratios, ...
Massive star formation around I05345+3157 -- I. The dense gas
infrared:associations: individual (IRAS05345+3157) – radio continuum:interferometric
2011/9/29
We present observations of the intermediate to massive star-forming region I05345+3157 using the molecular line tracer CS(2-1) with CARMA to reveal the properties of the dense gas cores. Seven gas cor...
A Correlation Between Surface Densities of Young Stellar Objects and Gas in Eight Nearby Molecular Clouds
Stellar Objects Gas Nearby Molecular Clouds
2011/9/28
We report the discovery and characterization of a power law correlation between the local surface densities of Spitzer-identified, dusty young stellar objects and the column density of gas (as traced ...
