The IACOB project
A new era in the study of Galactic massive OB stars


Useful tools

Tools developed in the framework of the IACOB project


Line broadening analysis

iacob-broad : A versatile, user-friendly IDL package for the line-broadening characterization of OB-type star spectra ( AANOTA.ME )

iacob-gbat : The IACOB grid-based automatic tool provides a fast and objective way to determine the stellar parameters and the associated uncertainties of large samples of O-type stars within a reasonable computational time. The tool consists of an extensive grid of FASTWIND models, and a variety of programs implemented in IDL to handle the observations, perform an supervised automatized analysis, and visualize the results.


Links to other tools of interest for the study of OB stars


Stellar atmosphere codes:

FASTWIND : A fast and easy to use NLTE line formation code for unified atmospheres with spherical extension and stellar winds, developed for the (routine) spectroscopic analysis of luminous blue stars, covering the spectral range from A to O and including central stars of planetary nebulae.

CMFGEN : A radiative transfer code designed to solve the radiative transfer and statistical equilibrium equations in spherical geometry.  It has been designed for application to W-R stars, O stars, and Luminous Blue-Variables.

TLUSTY : A user oriented package for modelling stellar atmospheres and accretion disks and for stellar spectroscopic diagnostics.

WMbasic : An easy-to-use interface to a program package which models the atmospheres of Hot Stars (and also SN and GN)


Stellar evolution codes and tools:

SYCLIST (SYnthetic CLusters, Isochrones and STellar tracks): Interactive tool coupled with the grids of Geneva's stellar evolution models.

Bonn's group webpage

BONNSAI (BONN Stellar Astrophysics Interface): A Bayesian statistical method that is capable of comparing all available observables simultaneously to stellar models while taking observed uncertainties and prior knowledge such as initial mass functions and distributions of stellar rotational velocities into account.


Spectral classification:

MGB : An IDL code that attacks spectral classification.


Line-profile variability and asteroseismic modelling:

FAMIAS : A package of state-of-the art software tools for the analysis of photometric and spectroscopic time-series data.


Other tools:

PHOEBE : A tool for modeling eclipsing binary stars based on photometric, spectroscopic, interferometric and/or polarimetric data.

CHORIZOS : A Bayesian IDL code for the analysis of photometric and spectrophotometric data using parameterized spectral energy distributions.

i-spec : A multi-purpose tool for the treatment and analysis of stellar spectra.
