Over 20 years ago Valenti & Piskuonov developed the stellar spectral synthesis library Spectroscopy Made Easy (SME) to simplify stellar spectral analysis, and it has been used in hundreds of works since.
PySME is a new Python frontend to the same library, developed with the same goal in mind: Making spectroscopy easier for everyone.
PySME creates accurate, high-resolution synthetic spectra, based on a range of stellar parameters, a linelist and a model atmosphere. It can also be used the other way around. Give PySME an observation and it will determine the best fit stellar parameters for that spectrum.
This is also useful for Exoplanet research. It is important to understand the host star, to properly understand the workings of the orbiting planet.
