Interstellar Sulfur Isotopes and Stellar Oxygen Burning
line survey has been made to study interstellar 32 S= 34 S and 34 S= 33 S ratios from the galactic disk. The four CS isotopomers were detected in 20 star forming regions with galactocentric distances between 3 and 9 kpc. From a comparison of line velocities, the C 33 S J=2{1 rest frequency is 250 kHz below the value given in the Lovas (1992) catalog. Taking 12 C= 13 C ratios from Wilson & Rood ...
متن کاملThe radial metallicity gradient in the Galactic disk
The aim of this work is to estimate the radial metallicity gradient in the Galactic disk toward the anticenter direction. For that we use Strömgren photometric data which allow us to compute individual physical parameters through empirical calibrations. We detect that metallicity calibrations found in the literature present discontinuities between photometric regions. By this, in the present wo...
متن کاملInterstellar Turbulence Driving by Galactic Spiral Shocks
Spiral shocks are potentially a major source of turbulence in the interstellar medium. To address this problem quantitatively, we use numerical simulations to investigate gas flow across spiral arms in vertically stratified, self-gravitating, magnetized models of galactic disks. Our models are isothermal, quasi-axisymmetric, and local in the quasi-radial direction while global in the vertical d...
متن کاملSedimentary sulfur isotopes and Neoarchean ocean oxygenation
Abrupt disappearance of mass-independent fractionation of sulfur isotopes (MIF-S) from the geologic record and an apparent ingrowth in seawater sulfate around 2.45 billion years ago (Ga) signal the first large-scale oxygenation of the atmosphere [the Great Oxygenation Event (GOE)]. Pre-GOE O2 production is evident from multiple other terrestrial and marine proxies, but oceanic O2 concentrations...
متن کاملRadial mixing in galactic discs
We show that spiral waves in galaxy discs churn the stars and gas in a manner that largely preserves the overall angular momentum distribution and leads to little increase in random motion. Changes in the angular momenta of individual stars are typically as large as ∼ 50% over the lifetime of the disc. The changes are concentrated around the corotation radius for an individual spiral wave, but ...
