The Structure of Brown Dwarf Circumstellar Disks
Christina Walker, Kenneth Wood, C. J. Lada +3
We present synthetic spectra for circumstellar disks that are heated by radiation from a central brown dwarf. Under the assumption of vertical hydrostatic equilibrium, our models y…
Dust and Gas in the Magellanic Clouds from the HERITAGE Herschel Key Project. II. Gas-to-Dust Ratio Variations across ISM Phases
Julia Roman-Duval, Karl Gordon, Margaret Meixner +32
The spatial variations of the gas-to-dust ratio (GDR) provide constraints on the chemical evolution and lifecycle of dust in galaxies. We examine the relation between dust and gas…
Spitzer Analysis of HII Region Complexes in the Magellanic Clouds: Determining a Suitable Monochromatic Obscured Star Formation Indicator
Brandon Lawton, Karl D. Gordon, Brian Babler +18
HII regions are the birth places of stars, and as such they provide the best measure of current star formation rates (SFRs) in galaxies. The close proximity of the Magellanic Cloud…
A Galactic-scale gas wave in the Solar Neighborhood
João Alves, Catherine Zucker, Alyssa A. Goodman +6
For the past 150 years, the prevailing view of the local Interstellar Medium (ISM) was based on a peculiarity known as the Gould's Belt, an expanding ring of young stars, gas, and…
The Formation of Submillimetre-Bright Galaxies from Gas Infall over a Billion Years
Desika Narayanan, Matthew Turk, Robert Feldmann +7
Submillimetre-luminous galaxies at high-redshift are the most luminous, heavily star-forming galaxies in the Universe, and are characterised by prodigious emission in the far-infra…
The Bones of the Milky Way
Alyssa A. Goodman, Joao Alves, Christopher N. Beaumont +8
The very long and thin infrared dark cloud "Nessie" is even longer than had been previously claimed, and an analysis of its Galactic location suggests that it lies directly in the…
