Molecular outflows: evolution, structure and angular momentum We present a theoretical model in order to explain the formation and the evolution of the molecular outflows associated to protostars. In this model, we assume that the molecular outflow is a thin shell formed by the interaction between a fast stellar wind and a rotating cloud envelope in gravitational collapse. We obtain a set of partial differential equations, these equations are space and time dependent, and describe the physical properties...

SO-IAA Colloquium: Recent advances about the exoplanetary exospheres The upper atmosphere of a planet plays a key role at protecting the lower altitudes from the effects of energetic stellar EUV and soft X-ray photons and keV-energy precipitating particles. Through a variety of transport processes, the upper atmosphere also participates in the net loss of a planet’s bulk composition into space. As such, the physics and chemistry occurring in the upper atmosphere influence the evolution of a planet over its... Antonio García Muñoz Technical University of Berlin, Germany |

Study of the diversity of AGN dust models The dust component of active galactic nuclei (AGN) produces a broad infrared spectral energy distribution (SED), whose power and shape depends on the fraction of the source absorbed, and the geometry of the absorber respectively. This emitting region is expected to be concentrated within the inner ∼5 pc of the AGN which makes almost impossible to image it with the current instruments. The study the infrared SED by comparison between infrared AGN... Dr. Omaira González-Martín IRyA - UNAM, Mexico |

SO-IAA Colloquium: Characterization of (exo)Planetary Atmospheres Characterization of planetary atmospheres has always been a challenge. While the next generation of facilities, such as ELT, JWST, and ARIEL, will improve our understanding of planetary atmospheres, the number of well-characterized exoplanet atmospheres is expected to remain limited. Large-scale simulations assist us with this shortcoming by predicting the diversity of the planetary atmospheres, connecting the spare observational measurements,...

SO-IAA Colloquium: Neutral and molecular gas outflows as tracers of the impact of radio jets Our view of the gas and its physical conditions in the central region of AGN has been enriched by the discover of fast and massive outflows of HI and molecular gas. These outflows can be driven by radiation/winds but also by the interaction of the radio plasma with the ISM. Understanding the origin and quantifying their impact requires to trace their location and derive their physical conditions (density of the gas, mass, mass outflow rate and...

Nebular HeII emission from spatially resolved metal-poor star-forming galaxies Nebular HeII1640,4686 emission, observed to be more frequent in high-z galaxies than locally, is indicative of far harder ionizing spectrum than that seen in nearby systems. Star-forming galaxies with lower metal content tend to have a larger nebular HeII intensities compared to those with higher metallicities. This agrees with the expected harder spectral energy distribution at the lower metallicities typical in the early universe. Theoretical... Dra. Carolina Kehrig IAA- CSIC |

Data mining Gaia DR2: the quest for Pre-Main Sequence Stars (and their discs) As the birth-sites of planets, protoplanetary discs have become the object of intense study during the last years. Constraining their typical lifetimes, masses and/or sizes is crucial to understand the process of planet formation. These objects are a natural by-product of early stellar evolution, and therefore a high fraction of Pre-Main Sequence Stars (PMS) are surrounded by a protoplanetary disc. The current census of PMS (and discs) has been... Dr. Héctor Cánovas Gaia Science Operations Centre, ESAC, Spain |

SO-IAA Colloquium: What's is the metallicity of cool dwarf stars? Cool dwarfs are the most numerous stars in the Galaxy and they account for most of its baryonic mass. However, they are likely the least understood main sequence stars. Their complex atmospheres, due to their low temperatures and high surface gravities, have made their spectroscopic study a hard task. Until recently, their basic physical properties, such as radii and mass, were poorly constrained due to the lack of empirical data. Stellar...

The Orientation of the Collimated Outflows of Planetary Nebula: Independence Day The discovery of collimated outflows in planetary nebulae (PNe) has changed the paradigm of PN formation. They actively participate in the nebular shaping immediately before or while fast stellar winds and D-type ionization fronts shock and swept the nebular envelope. The general properties of collimated outflows of PNe cannot be studied because projection effects do not allow us to determine their space velocities and linear sizes. The large...

Properties of ionized outflows in MaNGA DR2 galaxies Feedback originated from star formation and AGN activity in galaxies can have a significant impact on their evolution. The action of feedback leads to several processes that might have a significant effect on the surrounding gas, for example by heating the system, halting or enhancing star formation, or enriching the interstellar medium. Constraining the incidence and properties of feedback events such as ionized outflows is therefore crucial to... Bruno Rodríguez Del Pino CAB - INTA |

SO Colloquia: Searching extended line-emission objects in wide-field surveys: The IPHAS experience One of the problems we are facing in the study of evolved low- and intermediate-mass stars such as Planetary Nebulae (PNe) is the lack of completeness. Most known PNe belong to the bright or intermediate part of the luminosity function, leaving out those at the faint end. Any global chemical, kinematical, and physical analysis of the PN population is therefore biased. In 2003 the INT Photometric Halpha Survey started scanning the... Dra.
