Overview#

Introduction#

species provides a coherent framework for spectral and photometric analysis of directly imaged exoplanets and brown dwarfs. This page contains a overview of the various data that are supported and some of the tools and features that are available.

Supported data#

The toolkit benefits from publicly available data resources such as atmospheric model spectra, photometric and spectral libraries, evolutionary tracks, and photometry of directly imaged companions. The relevant data are automatically downloaded and added to the HDF5 database, which acts as the central data storage for a workflow. All data are stored in a fixed format such that the analysis and plotting tools can easily access and process the data.

The following data and models are currently supported:

Atmospheric model spectra

Tip

The available_models() method of the Database class can be used for getting a complete overview of all model grids, including details on the input parameters, wavelength range, $$T_\mathrm{eff}$$ range, and spectral resolution:

import species

species.SpeciesInit()

database = species.Database()
database.available_models()


Spectral libraries

Photometric libraries

Evolutionary tracks

Calibration

Dust extinction

Analysis tools#

After adding the relevant data to the database, the user can take advantage of the suite of tools that have been implemented for spectral and photometric analysis. Here is an incomplete list of available features and tools:
