PDRT: Photo Dissociation Region Toolbox

PDRT: Photo Dissociation Region Toolbox

Abstract: Ultraviolet photons from O and B stars strongly influence the structure and emission spectra of the interstellar medium. The UV photons energetic enough to ionize hydrogen (hν > 13.6 eV) will create the H II region around the star, but lower energy UV photons escape. These far-UV photons (6 eV < hν < 13.6 eV) are still energetic enough to photodissociate molecules and to ionize low ionization-potential atoms such as carbon, silicon, and sulfur. They thus create a photodissociation region (PDR) just outside the H II region. In aggregate, these PDRs dominates the heating and cooling of the neutral interstellar medium.

As part of the Web Infrared Tool Shed (WITS) we have developed a web tool, called the PDR Toolbox, that allows users to determine the physical parameters of a PDR from a set of spectral line observations. Typical observations of both Galactic and extragalactic PDRs come from ground-based millimeter and submillimeter telescopes such as CARMA or the CSO, or space-based telescopes such as Spitzer, ISO, SOFIA, and Herschel. Given a set of observations of spectral line intensities, PDR Toolbox will compute best-fit FUV incident intensity and cloud density based on our published models of PDR emission.

Based on the codebase landing page, I think the preferred citation for this is,

"If you use PDRT for your published or presented work, please reference Pound & Wolfire 2008, ADASS XVII, 394, 654 and Kaufman et al. 2006, ApJ, 644, 283. Thanks!"

That's 2008ASPC..394..654P or 2006ApJ...644..283K

Also, there's a "Suggest a change or addition" button at the bottom of every code page. Should I use that or continue using the forum for any updates that I spy?

Thank you very much! I've added this information to the entry.

Please continue to use the forum. We need to improve the "Suggest a change or addition" workflow; it's a little rough right now.

Thank you!!
