As an astronomer your life consists (mostly) on developing computer software, writing papers to show the results of your research and applying for telescope time. The latter means you apply for telescope time by writing proposals that describe the project you want to carry out and the scientific motivation behind it. If your proposal is accepted you go directly to the telescope to observe your stars. Then, you come back to the office and analyze the new data acquired applying and fitting models to detect new planet candidates. I’m interested in detecting ‘rocky’ small planets around bright stars, so for this purpose I use the radial velocity method for exoplanet detection using both the Carnegie Planet Finder Spectrograph (PFS) at Las Campanas Observatory and the High Accuracy Radial velocity Planet Searcher (HARPS) at La Silla Observatory.
