  • The comparison between the observed Spitzer spectrum (in black) and the synthetic spectral energy distribution (SED; in red) of a dual dust chemistry AGB star in the Large Magellanic Cloud. We report the luminosity and effective temperature of the star, and the following parameters for the internal and outer dust shells: optical depth (at 1 µm), dust temperature, dust composition and distance from the central star.
    Dual dust chemistry around evolved stars of the Large Magellanic Cloud

    During the final stages of their lives, stars with masses between one and eight times the mass of the Sun evolve along the asymptotic giant branch (AGB). AGB stars expand and loss a major fraction of their mass through stellar winds. The low temperature and high density of AGB winds provide ideal conditions for the condensation of dust grains in their circumstellar envelopes. Gas and dust are expelled into the interstellar medium, becoming an essential component for the formation of new stars and planets. Therefore, studying the type of dust (solid state organic or inorganic components) and

    Literature and Astronomy: connected universes

    The participants in the second Hispano-American Festival of Authors which is taking place in Los Llanos de Aridane (La Palma) paid a visit, yesterday, to the Roque de los Muchachos Observatory during a day when Astronomy played the main role. During the afternoon there was a panel discussion in tribute to the Founding Director of the instituto de Astrofísica de Canarias, Francisco Sánchez, and at night the opportunity to observe the sky with amateur telescopes. "The Inspiring Force of the Universe. Tribute to Francisco Sánchez" was the topic of the panel discussion which brought together
