The Green Astro-comb at TNG and HARPS-N

Speaker: David Phillips (Harvard-Smithsonian Center for Astrophysics)

Date and time: 2013-02-06 11:00

The astro-comb, a new calibration source based on a laser frequency comb is now installed at the TNG and initial demonstrations of its capabilities for calibrating HARPS-N are in progress. I will present an introduction to the ideas behind laser frequency combs in general and the green astro-comb specifically and present some preliminary data that we have taken over the last few days and evenings as we commission the green astro-comb.
