THOT: Dating stars Life, planets, exoplanetary systems, stars, and our galaxy evolve with time, and the best and sometimes only way for understanding this evolution is dating stars. THOT is a Marie Curie Project devoted to gathering and updating all the stellar dating techniques into a single computational tool. In this presentation, I will present some of the most promising techniques for stellar dating, and show the current main contributions of this project (... Dr. Andres Moya |

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 |
