SUMMARY:SO Colloquium - Origin and impact of protostellar outflows: the ALMA and JWST revolution
DESCRIPTION:The birth of stars\, and of planets around them\, is universally associated with a spectacular bipolar ejection phenomenon that extends from stellar to parsec scales. Its manifestations include a narrow and fast axial jet\, surrounded by a broader and slower molecular outflow carrying a large amount of mass. \nThe exact origin of these dual phenomena\, their role in the removal of excess angular momentum\, and their impact on star and planet formation\, have all been a subject of fierce debate and active research over four decades. \nIn this talk\, I will review major progress on these topics obtained from new observational facilities (from the optical to the millimeter range) and from enhanced modeling capabilities. In particular\, I will highlight recent results from ALMA and JWST and how they could revolutionize our understanding of the origin and impact of protostellar outflows. \nFecha y lugar: 21/05/2026 – 12:30 | Salón de ActosSylvie CabritObservatory of Paris\, France \n  \n

SUMMARY:Round table - Astrophysical Jets in Contrasting Environments and Scales
DESCRIPTION:Jets are present on multiple astrophysical scenarios\, from protostars to supermassive black holes. Despite the enormous differences in their energetics\, these jets appear to share several basic properties. Thanks to their proximity and the richness of their detectable multi-wavelength emission (free-free and synchrotron continuum\, as well as atomic\, ionized\, and molecular lines)\, the physical properties of protostellar jets can be studied in great detail\, together with their connection to the associated accretion disk\, the mechanisms responsible for their launching and collimation\, and their interaction with the surrounding environment. \nThe knowledge gained from young stellar objects may therefore offer valuable insights into jets in other astrophysical systems. Three experts will come together to explore this possibility\, discussing the similarities and differences among jets in various contexts. \nFecha y lugar: 26/05/2026 – 12:30 | Salón de ActosSylvie Cabrit (Observatoire de Paris\, France) & Doug Johnstone (National Research Council Canada – Herzberg Astronomy and Astrophysics Research Centre\, Canada) \n

SUMMARY:SO Colloquium – What the Variability of Embedded Protostars Tells Us about Accretion: Past\, Present\, and Future
DESCRIPTION:The James Clerk Maxwell Telescope (JCMT) has been monitoring eight nearby low-mass star-forming regions in the Gould Belt at submillimetre wavelengths for more than eight years to search for and quantify the time dependent brightness variability of the resident deeply embedded protostars. \nSecular variability is common among these protostars; greater than 25% of the sample show measurable long-term brightness changes and 10% show burst behaviour lasting months to years. We interpret this secular variability as reflecting changes in the mass accretion rate from the disk to the protostar\, as predicted by theoretical models of (proto)stellar assembly. For a subset of our sample we have contemporaneous mid-IR light-curves which allow additional constraints on the conditions responsible for the brightness variations\, confirming that the submillimetre variability is driven by changes in the dust temperature profile of the envelope. \nFurthermore\, we have combined\, for one source\, single dish and interferometric sub-mm monitoring\, which has allowed us to unambiguously recover a time lag in the variability at larger angular scales and use the results to confirm the envelope structure surrounding the embedded protostar. \nFecha y lugar: 28/05/2026 – 12:30 | Salón de ActosDoug JohnstoneNational Research Council Canada – Herzberg Astronomy and Astrophysics Research Centre \n  \n

SUMMARY:Los eclipses en el arte
DESCRIPTION:Los eclipses solares han sido una de las experiencias naturales más impactantes para la humanidad. La desaparición momentánea del Sol como fuente de vida\, orden y estabilidad\, ha despertado fascinación\, temor y asombro en prácticamente todas las culturas. Por ello\, los eclipses no solo han sido objeto de estudio astronómico\, sino que también se han convertido en poderosos símbolos artísticos\, religiosos y políticos. \nEsta charla propone un recorrido por distintas manifestaciones artísticas inspiradas en los eclipses solares a lo largo de la historia\, desde la Antigüedad hasta el arte contemporáneo. A través de diferentes periodos y culturas\, exploraremos cómo este fenómeno celeste ha sido interpretado\, representado y transformado en imágenes y obras de arte que reflejan la profunda fascinación que el eclipse ha ejercido sobre la humanidad. \nFecha: 28/05/2026 – 19:00Conferenciante:  María Balaguer JiménezFiliación:  Instituto de Astrofísica de Andalucía (IAA-CSIC) \n  \n
