X-ray emission from Symbiotic Stars: a stellar window to the Astrophysics of AGN Symbiotic stars (SySts) are binary systems in which a white dwarf (WD) accretes material from a red giant star. X-ray studies of SySts reveal an apparent variety of processes which would suggest different origins. In this talk I will briefly review our current knowledge of the X-ray properties of SySts (their classification and physical parameters), in particular I will describe the iconic systems R Aqr and CH Cyg. Finally I will present our... Dr. Jesús Toalá |

SO Colloquium: The demographics of small exoplanets The diversity of the exoplanet population is beyond our imagination. The more than 5000 known exoplanets vastly differ in mass, size, orbital period, dynamics, and host type. Demographic studies, however, aim to find patterns in the population that inform us about their origin, composition, and evolution. Among these features, perhaps the most surprising is the abundance of planets with no analog in the solar system, also known as sub-Neptunes.... Dr. Rafael Luque |

SO Colloquium: The evolution of the accretion process: investigating the protostellar phase to constraints planet formation The accretion process is responsible for the mass building during the star formation phase, but our knowledge of this phenomenon is still not totally understood. On one side, the magnetospheric accretion scenario describes the accretion on pre-main sequence (Class II/III) low-mass stars. However, most of the material is supposed to be accreted during the earliest stages, i.e. the protostellar phase (Class 0/I), when the forming star and its disk... Dr. Fiorellino, Eleonora |

The Galactic Center seen with MeerKAT During its inauguration, the MeerKAT released, to date, the most detailed image of the centre of the Galaxy at L-band (1.28 GHz). Since then, the data have been exploited for various scientific research. One such exploitation was to produce a high resolution mosaic of the Galactic centre. From this mosaic came a catalogue of newly discovered unresolved point sources. Over 1500 sources were identified, of which 20 are steep spectrum point... Dr. Isabella Rammala |

SO Colloquium: The tidal arms of open star clusters are much longer than thought, but more difficult to find The tidal arms of stellar clusters are an important tool for studying the clusters’ birth conditions, their evolution, coupling, and interaction with the Galactic potential. They also help understand how field stars populate the Milky Way. Thanks to Gaia, much progress has been accomplished in finding the tidal arms of open clusters. I will show here that such arms are much longer than previously observed, and that their identification requires... Dr. Henri Boffin |

Fenómenos eléctricos en atmósferas planetarias: ¿Qué son y cómo nos afectan? Aunque las investigaciones sobre la naturaleza eléctrica de la atmósfera terrestre arrancan a mediados del siglo XVIII, con las primeras aportaciones sobre la electricidad de las tormenta realizadas por Benjamín Franklin entre 1749 y 1752, a día de hoy persisten muchos interrogantes.

SO Webloquium: Feeding and Feedback: How to Make a Starburst and What that Means for the Host Galaxy The cycle of star formation governs the evolution of galaxies. In some local galaxies, the star formation rate in their centers are much higher than other normally star-forming galaxies and may be more similar to galaxies at earlier cosmic times. I present observational results from two archetypal nearby starburst galaxies: NGC253 and M82. First, I will discuss how gas flows to the center of NGC253 along its bar to fuel the extreme burst of... Dr. Rebecca C. Levy |

SO Colloquium: The transition between super-Earths and sub-Neptunes: Interior and atmosphere modelling of the low-mass planet population Low-mass exoplanets are showing a diversity in their densities, ranging from silicate-dominated super-Earths to volatile-rich sub-Neptunes. We have developed a coupled interior-atmosphere model that estimates the composition and interior structure of super-Earths and sub-Neptunes assuming water and CO2 atmospheres. The applications of the model include the homogenous analysis of a sample of multi-planetary systems, as well as the assessment of... Dr. Lorena Acuña |

The correct interpretation of solar data requires sophisticated theories. The solar chromosphere is made of strongly stratified... Dr. Elena Khomenko |

A VLTI view of Massive Young Stellar Objects (MYSOs) The formation of massive stars, objects with masses larger than 8 times solar, is central to both stellar astronomy and galactic evolution. In recent years, significant progress has been made in understanding the formation of high-mass young stellar objects (MYSOs; i.e. M∗ ≥ 8 M⊙, Lbol ≥ 5 x 103 L⊙. The latest observational and theoretical studies present evidence that HMYSOs are born in the same way as their low-mass counterparts, via disc... Dr. Maria Koutoulaki |

Near-Infrared Observations of Clustered Massive Star Formation in Outflowing Region AFGL 5180 Massive stars are significant throughout the universe, as they impact their surroundings from the early stages of their formation until they die in the form of supernova. Observations in the near-infrared (NIR) of the bright and large-scale (~pc) jets which young stars ubiquitously produce during their formation process can place important constraints on the phenomenon of massive star formation. Here, we present a detailed NIR view of the star-... Sam Crowe |

Polarimetric imaging of M87* with the EHT enabled significantly stronger inferences on the black hole and accretion parameters than total intensity data alone. Geometric modeling was a central tool for studying the structure of M87* and Sgr A* in total intensity. In... Dr. Freek Roelofs |

In order to better understand their formation and evolution, N-body simulations are needed. These simulations are developed assuming a star close to the substellar mass limit as the central object. The simulations include tidal and general relativistic effects that incorporate the contraction and evolution... Dr. Mariana Sánchez |

Off-centre supermassive black holes in bright central galaxies Supermassive black holes (SMBHs) are believed to reside at the centre of massive galaxies such as brightest cluster galaxies (BCGs), the most massive galaxies which can be found in today's Universe. However, as BCGs experienced numerous galaxy mergers throughout their history, the central BH can be significantly kicked from the central region by these dynamical encounters. By combining the Illustris-TNG300 simulations and orbital integration... Dr. Aline Chu |

J-PAS: a survey for tracing the role that star formation and environment play in galaxy evolution The processes that explain the evolution of galaxies from the blue cloud to the red sequence are still under discussion. Internal processes, named as mass-quenching, because they are linked to the galaxy mass or AGN feedback, could be responsible of the rapid quench of the star formation in galaxies. Besides the stellar mass, the evolution of the galaxy populations is also a function of the environment. Unlike the mass quenching, the... Dr. Rosa González Delgado |

Sub-milliarcsecond astronomy with Imaging Atmospheric Cherenkov Telescopes The angular size of a star is a critical factor in determining its basic properties. Together with the distance, it provides the physical diameter of the star which can be used to yield luminosity and mass estimates. Direct measurement of stellar angular diameters is difficult: at interstellar distances stars are generally too small to resolve by any individual imaging telescope. This fundamental limitation can be overcome by several methods... Dr. Tarek Hassan |
