Papers, Preprints, Data

Here are some papers/preprints, data, and Fortran programs, as listed below; these include material relevant to:
- stellar evolution and nucleosynthesis: Fortran programs and papers,
- the Sun and helioseismology,
- HI mapping at intermediate Galactic latitude (GHIGLS)
- the VLA Galactic Plane Survey (VGPS) of 21-cm line emission from neutral atomic hydrogen,
- and interactions of hydrogen molecules in the interstellar medium.

Most papers are available in PDF form and/or as gzip-compressed PostScript files, with figures in mid-text (the latter must be processed by "gunzip FILE.ps.gz", unless your browser does this automatically).

Stellar Properties Fortran Programs:

(Version of 7 September 2007): Fortran routines to obtain OPAL opacities at arbitrary metallicities, rather than having to pre-compute opacities at a single metallicity
- i.e., opacities can be obtained at run-time as a function of metallicity Z, as well as hydrogen abundance X, temperature, density, and excess C and/or O; optionally, interpolation in varied C,N,O,Ne composition is also allowed.
- Optional extension is now allowed via conductive opacities (updated Potekhin et al. 2006 electron thermal conductivities are now supported) and/or molecular opacities (updated Ferguson et al. 2005 molecular opacities are now supported).
