The National Science Foundation’s Arecibo Observatory and the Planetary Habitability Laboratory of the University of Puerto Rico at Arecibo joins forces with Red Dots today to learn a bit more about the nearest red-dwarfs and its possible planets. This collaboration will simultaneously observe in both the optical and radio spectrum Barnard’s Star, a popular star in the science fiction literature. Next week we will have a few more articles here on Red Dots on the history of this remarkable star (featuring a special guest article by Centauri Dream‘s author Paul Gilster). Those adept to science fiction literature may recall that Arecibo’s telescope is the mythical observatory where Dr. Ellie Harroway starts her Search for Extra Terrestrial Intelligence (or SETI) in Carl Sagan’s novel and film Contact, so the execution of these coordinated observations is a special event for us.
Observations on Barnard’s star will last for about 1.5 hours and they will be carried out at the so-called C-band, which corresponds to frequencies between 4 to 5 GHz. For comparison, kitchen microwave ovens work at frequencies of about 2.5 GHz. These will be complemented with spectra, and photometric monitoring with the follow-up facilities already being used in Red Dots including; ...
