Analysis tools for solar-like oscillators
The tools
The following tools have been produces as one of the deliverables for
the SPACEINN network.
The SPACEINN network is
funded by the European Community's Seventh Framework Programme (FP7/2007-2013)
under grant agreement no. 312844.
- InversionKit: a software for
carrying out various types of 1D inversions (rotation and structure)
as well as inversions for integrated quantities.
- AIMS: a software for obtaining stellar
parameters and confidence intervals, using classical and seismic
constraints.
- InterpolateModel: a software for interpolating
the acoustic structure between multiple models.
- InversionPipeline: a software for carrying out
inversions by automatically selecting reference models from
grid(s) of models.
- NonLinearKit: this is a somewhat experimental
non-linear stellar structural inversion tool provided on an as-is basis.
Workflow
Some of the above tools may be used in conjunction. Accordingly, we
propose the following work flow:
- Use AIMS to calculate a representative
set of models for a given set of seismic and classical constraints.
Each model from this set will typically result from interpolation in
a grid of models, and will accordingly be described as a linear
combination of models. AIMS provides the relevant model names and
interpolation coefficients in one of its output models. Given the
time it takes to carry out the next two steps, one will take a sub-sample
of the models produced by AIMS (typically with 100 models or so).
- Use InterpolateModel
to combine the above models and find their acoustic
structure using the above list produced by AIMS.
- The above set of interpolated models can then be fed into
InversionPipeline, thereby allowing
a systematic application of inverse methods.
