HITRAN and HITEMP Database
With techniques developed in quantum mechanics, molecular spectra can be modeled by a set of discrete fundamental parameters. The knowledge of these reference molecular spectroscopic parameters is essential to correctly characterize constituents of their environments, model their spectra and atmospheric conditions. Physicists at the Center for Astrophysics | Harvard & Smithsonian maintain the HIgh-resolution TRANsmission (HITRAN) and HIgh TEMPerature (HITEMP) databases of molecular spectral parameters, along with the HITRAN Application Programming Interface (HAPI) which also enables one to access the database archive and process the data.
Sensing the Dynamic Universe
The Sensing the Dynamic Universe (SDU) project creates sonified videos exploring the multitude of celestial variables such as stars, supernovae, quasars, gamma ray bursts and more. We sonify lightcurves and spectra, making the astrophysics of variables and transients accessible to the general public, with particular attention to accessibility for those with visual and/or neurological differences.
