From protostars to planets: the astrochemical link Protostars accrete their material from the natal cloud through accretion disks. These disks are progressively dispersed by the recently formed star to form protoplanetary discs in which planets are born. Although this process takes a few million years, now we think that the final chemical composition of the gas and dust in the proto-planetary disk is to a large extent determined by the chemical evolution in the natal cloud. Determining the... Dr. Asunción Fuente |

Inverse Compton emission revealed by observations up to TeV energies of GRB 190114C The hunt for Gamma-Ray-Bursts (GRBs) at very high energy (VHE) started more than 20 years ago. A hint of emission was already claimed by Milagrito from the observations of GRB 970417. On 19 of January the Major Atmospheric Gamma Imaging Cherenkov (MAGIC) clearly detected GRB 190114C above 0.2 TeV. This is the first highly significant detection (over 50sigma reached in the first few tens of minutes after the burst) of a GRB at VHE. GRB190114C... Dr. Elena Moretti |

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 |

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 |

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... Dr. Alejandro López Vázquez |

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 |

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... Bárbara Rojas-Ayala |

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 |

The Arp299 puzzle. Black holes that devour stars In January 2005, a bright flash was detected in the nucleus of the galaxy in the process of fusion Arp 299-B, which was considered a supernova explosion. However, ten years of observations at different wavelengths have allowed us to witness how the luminous region was lengthening and expanding, and to conclude that it is a jet of material expelled by the galaxy's central super-massive black hole after tearing a star.

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 |

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. Laurence Sabin |

What we (don't) know about the trans-Neptunian objects The first trans-Neptunian object was discovered in 1930 and we waited over 60 years to discover the second one. The discovery of Albion (a.k.a. 1992QB1) enticed the minor bodies community to characterize the new population, called collectively as trans-Neptunian objects (TNOs). Today we know the existence of over 2,000 objects and counting. Nevertheless, it seems that we have reached our technological limitation in terms of observational studies...

The planetary nebula HuBi 1, a rebel with a cause Planetary nebulae, the descendants of low- and intermediate-mass stars, have characteristic onion-like ionization structure, with the highest ionization species closer to the central star. This is true for all planetary nebulae, but HuBi 1, which shows an inverted ionization inner shell. There is a reason for this oddity, a peculiar stellar evolution of its central star, which makes HuBi 1 the missing link of the population of cool C-rich... Dr. Martin Guerrero |

Optical spectroscopy of local type-1 AGN LINERs The Balmer emission originated in the broad line region (BLR) of active galactic nuclei (AGNs) could be either weak and difficult to detect, or even absent, for low luminosity AGNs, as low ionization nuclear emission-line regions (LINERs). This makes LINERs challenging to fit in the AGN unification scheme. Moreover, a long debate can be found in the literature proposing different ionization sources at the origin of optical emission lines and no... Dr. Sara Cazzoli |

The peculiar case of the active galactic nuclei in PBC J2333.9-2343 Under unification schemes, active galactic nuclei (AGN) can be explained by orientation effects. However, some sources show properties at different frequencies that led to incongruent classifications and cannot be explained by such unification scheme. This is the case of PBC J2333.9-2343; its optical spectrum is of a type 2 AGN but its X-ray spectrum does not show signs of absorption, and in the radio it has many features typical of a blazar but...

Physical and statistical properties of High Frequency Peaked blazars In the class of active galactic nuclei (AGNs), blazars are the most extreme objects, with their relativistic jets closely aligned to our line-of-sight. The emission of blazars is mostly non-thermal, spanning the entire electromagnetic spectrum, and is often linearly polarized providing us with important insights on the magnetic field structure. An emerging radio-loud AGN population is represented by high synchrotron peaked (HSP) blazars,... Dr. Lico |

Lightning – from Its Base to Space Lightning has been studied for centuries with surprisingly meager progress since the early breakthroughs of Franklin. There are numerous reasons for this lack of progress: lightning is complex, it is very energetic with large peak power - hard for in-situ probes to survive, it is spatially and temporally sparse – hard to place a sensor in an optimal location. However, modern technological advances and innovations have led to new remote... Prof. Hugh Christian |
