In our quest for large organic molecules in the interstellar/circumstellar medium, the main difficulty is to disentangle their spectral signatures among the observed forest of bands. We propose a new approach to the problem, by defining a number of key transitions coming from parts of the whole molecule and that would characterize its...

Context. Achernar, the closest and brightest classical Be star, presents rotational flattening, gravity darkening, occasional emission lines due to a gaseous disk, and an extended polar wind. It is also a member of a close binary system with an early A-type dwarf companion. Aims: We aim to determine the orbital parameters of the Achernar...
