  • 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

    The IAC collaborates again with the Hispano-american Festival of Authors, in La Palma
    The second edition of this festival, which will be inaugurated tomorrow, Tuesday, until Saturday 14th September in the La Palma municipality of Los Llanos de Aridane and which will be attended by the Nobel Laureates in Literature Mario Vargas Llosa and Jean-Marie Gustave Le Clézio, will again have a day dedicated to astronomy. Those present at the meeting will visit the Roque de los Muchachos Observatory and after a panel discussion in honour of the founding Director of the IACV Francisco Sánchez, will make an observation with night-time amateur telescopes. For the second consecutive year

    Sharper view of the cosmos through reproducible science
    The team led by the researcher from the Instituto de Astrofísica de Canarias (IAC) Mohammad Akhlaghi has obtained a European grant to develop a project focused on the handling of large quantities of data, and the capacity to be able to reproduce any scientific result by another research group.
