Abstract
I present the software tool of the
HELAS NA5 Workpackage Frequency Analysis and Mode Identification
for Asteroseismology. We term this tool FAMIAS.
It will be a collection of
software tools for the frequency analysis and mode identification of photometric
as well as spectroscopic data of oscillating stars packed into a graphical user
interface. The workpackage is currently in the stage of development and will be
made publicly available in a well documented form at the end of 2007. The
creation of this data analysis tool is one of the objectives of the NA5
workpackage "Asteroseismology" within HELAS. For the spectroscopic mode
identification, the moment method as well as various methods based on the
Doppler broadening of the line profile will be implemented. The photometric mode
identification will be based on the method of amplitude ratios and phase
differences in different passbands. Therefore, pre-computed grids with the
frequency values and their non-adiabatic eigenfunctions in the outer atmosphere
for different kinds of stars will be included in the package.
