At certain evolutionary stages, some stars generate circumstellar disks. Within these disks, the temperature is such that it allows for the formation of molecules. The presence of these molecules is detected by the appearance of molecular bands in emission within the spectra of these stars. To identify the present molecules and determine the physical parameters of the regions within the disk where the molecules are located (temperature, density, etc.), it is necessary to have synthetic spectra for comparison with the observed spectra.

To obtain synthetic spectra, we have developed the DisMol code, which allows for the generation of spectra for various diatomic molecules in a rotating circumstellar disk. Details of the code and its capabilities will be available in a paper currently under development.

On this page, we display several spectra of different molecules, obtained using the DisMol code.
