What can I do with TARDIS? | ||
************************** | ||
|
||
TARDIS is designed to carry out calculations of synthetic supernova spectra (see Kerzendorf & Sim 2014). A TARDIS calculation requires | ||
|
||
1) a model for the supernova eject (density and composition distribution) to be specified; | ||
2) parameters determining the physical and numerical properties of the code are give. | ||
|
||
These inputs are specified via the input file (yaml file). As a starting point, examine the input file in the example download (above). The example file sets up a very simple model in which the density distribution is based on the well-known W7 model () and in which uniform abundances are specified. To get you started, here is a short list of settings that can be experimented with to get a feel for using TARDIS. Please contact us if you have questions or woudl like information on more advanced possibilities! | ||
|
||
Change the abundances | ||
=============== | ||
|
||
In the example file you can alter the elemental abundances (mass fractions; specified in the "abundances" section). Use this to explore the sensitivity of features to composition. | ||
|
||
Change the luminosity | ||
============== | ||
|
||
You can alter the (emergent) luminosity and see how this affects the synthetic spectrum. Do this by varying the "luminosity requested" in the "supernova" section. | ||
|
||
Change the epoch | ||
=========== | ||
|
||
In the example file, you can change the epoch for which the synthetic spectrum is calculated (change the value of "time explosion"; specified in the "supernova" section). When doing this you might also change the inner boundary velocity ("start" value in the "velocity" section), and probably the luminosity (see above)! | ||
|
||
Experiment with the treatment of line opacity | ||
============================= | ||
|
||
In the "plasma" section you can change the "line interaction type" between "scatter", "downbranch" and "macroatom" - investigate how important fluorescence is in your synthetic spectrum. (See Kerzendorf & Sim and references therein for the meaning of these settings.) | ||
