Early times of the ROA-Montsec Baker-Nunn camera
I found among my archives the article by Michael R. Pearlman with title «Early Experience of the SAO Satellite-Tracking Program», originally published in EOS: Transactions of the American Geophysical Union –The Weekly Newspaper of Geophysics). This piece explains the origins of the world-wide network of fast photographic cameras set up in the fifties by the United States of America (the Smithsonian Astrophysical Observatory), for artificial satellite follow-up. The network played an interesting role in the early times of the research on orbital dynamics, and it got the first Western measurements of the orbits of Soviet spacecraft. The article includes the first Western image of Sputnik 1 (the booster, in fact).…

Summaries of SpS17 Discussions IAU GA 2012 Special Session on Light Pollution
D. Galadí-Enríquez took part in the XXVIII General Assembly of the International Astronomical Union in Beijing, 2012, specifically in the session on protection of the night sky. There I had the chance to present a summary on «Legal protection of the night sky in Andalusia (Western Europe)», prepared in collaboration with Ángela Ranea-Palma, from the Ministry for the Environment of the Regional Government of Andalusia (Junta de Andalucía). Here you can download the summary of our talk, and in this second link you will find the slides used during the speech. Also, I chaired the discussion on blue light of the Special Session on Light Pollution and I prepared the…

Stellar Structure and Habitable Planet Finding
Stellar Structure and Habitable Planet Finding was publshed by the European Space Agency as Special Publication number 485. The book contains the proceedings of the First Eddington Workshop, celebrated in Cordova (Spain) in 2001, with David Galadí-Enríquez as coordinator of its local organising committee. The proceedings were edited by Fabio Favata, Ian W. Roxburgh and D. Galadí-Enríquez. Download here the complete proceedings. Eddington was a project for an ESA mission devoted to the search of extrasolar planets applying the photometric transit method. The mission would have been useful, too, for astroseismology studies oriented towards the study of stellar structure. The workshop discussed the mission profile, spacecraft, payload and scientific cases.…
