Overall, they predicted that discs around massive young stars should be at least marginally resolved, which is essentially the case given the evidence for discs in recent years mentioned above. The spirit of this comparatively early work is similar to many current models/synthetic observations and ...
Feltzing and Gustafsson (1998) found that most elements showed a rather flat trend above solar metallicity but that, for example, [Na/Fe] notably increases with [Fe/H]. They found that this increase was not due to any particular orbit of stars, but seemed to be a common feature in the...
Simulation of hypervelocity stars (HVSs) trajectories originating in Andromeda for my paper "On Stellar Migration from the Andromeda Galaxy". The base of this code is the simulation I developed for my Master's thesis project. For the paper based on it, I improved the simulation. The purpose ...
See the linked documentation above for more details. Published IMFs we include are Salpeter1955(mmin::Real=0.4, mmax::Real=Inf) Chabrier2001BPL(mmin::Real=0.08, mmax::Real=Inf) Chabrier2001LogNormal(mmin::Real=0.08, mmax::Real=Inf) Chabrier2003(mmin::Real=0.08, mmax::Real=Inf) ...
SN and the energetic particles from the shock interaction between the ejecta and the inner shell. Results similar to the outer shell can be derived by comparing the above CSM masses and the dust mass (6.0 × 10−3 M⊙) located at 2.6 × 1017 cm in the single-shell ...
2c). The data to model ratios, however, show a clear excess of emission at energies above ~0.7 keV (Fig. 2b), suggesting that the single blackbody model is not enough to describe the X-ray spectrum of XMM2. The spectral fitting result is improved significantly by the addition of a...
One of the biggest questions hanging over solar (and indeed, stellar) physics is how the sun (and other stars) heat the corona. As we all know, the sun is veryhotbut its corona is too hot; the photosphere is a few thousand degrees, whereas, only just above it, the coronal plasma ...
The “main” array has been fully operational since March 2008, and is sensitive to showers with E≳1EeV and zenith angles up to 45° (and up to 55° above 1018.8 eV); the Telescope Array Low-energy Extension [1186], consisting of 10 extra FD telescopes looking at higher elevations ...
(2007)found about 40% of SiC grains with Ne-G contents above detection limit. Concentrations ranged up to 1.5×10−2cm3STP/g for grains from Murchison and up to 2.7×10−2cm3STP/g for a grain from Murray. These authors could also confirm that in the grains richest in22Ne, the Ne...
1_err (outputs of calcDust) are None, so we can disregard them. Similarly, dac, n, tau, n_err, and tau_err refer to the parameters of the effective dust screen rather than diffuse dust. The plot below is an example of the type of image that would be produced from the code above...
