  • Ad orientem: Las iglesias románicas del Camino Francés en los reinos de Castilla y León bajo la perspectiva de la Astronomía Cultural*Ad orientem: Romanesque Churches of the French Way in the kingdoms of Castile and Leon from a Cultural Astronomy perspect

    RESUMEN: En este trabajo se examina, desde la perspectiva de la Astronomía Cultural, si las iglesias románicas del Camino de Santiago siguen un patrón de orientación común a todas ellas. Para ello, se ha obtenido la orientación Ambos reinos comparten orientaciones hacia la salida del sol el domingo de Pascua, probablemente obtenidas en su mayoría

  • AGB Stars and Their Circumstellar Envelopes. I. the VULCAN Code

    The interplay between AGB interiors and their outermost layers, where molecules and dust form, is a problem of high complexity. As a consequence, physical processes like mass loss, which depend on the chemistry of the circumstellar envelope, are often oversimplified. The best candidates to drive mass-loss in AGB stars are dust grains, which trap

  • AGB Stars and Their Circumstellar Envelopes: An Operative Approach to Computing Their Atmospheres

    The study of AGB stars necessarily covers a wide range of topics, from the primary astronomical observations to their interpretation in terms of fundamental physics. All that requires proper ad hoc methodologies, among which numerical modeling of the outer layers of AGB stars plays a paramount role. In this paper, we present an iterative sequential

  • Anomalously porous boulders on (162173) Ryugu as primordial materials from its parent body

    Planetesimals—the initial stage of the planetary formation process—are considered to be initially very porous aggregates of dusts1,2, and subsequent thermal and compaction processes reduce their porosity3. The Hayabusa2 spacecraft found that boulders on the surface of asteroid (162173) Ryugu have an average porosity of 30-50% (refs. 4-6), higher

  • A space mission to map the entire observable universe using the CMB as a backlight

    This Science White Paper, prepared in response to the ESA Voyage 2050 call for long-term mission planning, aims to describe the various science possibilities that can be realized with an L-class space observatory that is dedicated to the study of the interactions of cosmic microwave background (CMB) photons with the cosmic web. Our aim is

  • Microwave spectro-polarimetry of matter and radiation across space and time

    This paper discusses the science case for a sensitive spectro-polarimetric survey of the microwave sky. Such a survey would provide a tomographic and dynamic census of the three-dimensional distribution of hot gas, velocity flows, early metals, dust, and mass distribution in the entire Hubble volume, exploit CMB temperature and polarisation
