Exploring the importance of location and environment in star formation. Danae Polychroni (Universidad de Atacama – INAF-IAPS)
Oct 27 @ 15:00 – 17:00
Abstract:  The last few years have seen the advent of new technologies in the sub-mm and IR regimes that allow for unprecedented quality observations of star forming regions. As such we are finally able to produce statistically significant samples of star forming cores at the same time as mapping their surrounding environment with high spatial resolution. In this talk I will present results from the Herschel Space Observatory Gould Belt and HOBYs surveys that covered the Orion A Molecular Cloud complex and the W3 Giant Molecular Cloud. Both these regions contain intermediate to high mass star formation and a rich environment that includes triggered and spontaneous star forming regions as well as a plethora of filaments. We have obtained a statistically significant sample of star forming cores located in different environments and thus derived the properties both of the dense cores as well as their surrounding environment. As such, in this talk I will discuss the role of the environment in deciding the final mass of the forming stars with a focus in the presence of filaments and triggering phenomena in these two star forming regions.

The orbital and astrochemical signatures of giant planet migration around the Sun and beyond. Diego Turrini (INAF-IAPS – Universidad de Atacama)
Oct 30 @ 15:00 – 17:00

Abstract: For decades the Solar System has been our sole example of a planetary system, resulting in the classical view of planetary formation as a local, orderly process producing stable planetary systems. The ever growing sample of known exoplanets, however, has shown us the major role played by orbital migration and chaos in determining the evolution of planetary systems in our galaxy. This brought to questioning our very understanding of the history of the Solar System and to suggesting that it also could have undergone a more violent evolution than previously thought. In this talk I will describe how the compositional information on the planetary bodies of the Solar System can be used to shed new light on its past, illustrating the past and current investigations performed in the framework of the NASA missions Dawn and Juno, and I’ll discuss how the same principles, if not the same techniques, can be used to investigate of histories of extrasolar planets.

The Orion Radio All-Stars: new perspectives in stellar radio astronomy. J. Forbrich (University of Hertfordshire UK)
Nov 6 @ 15:30 – 17:00

Abstract:
With significant new observing capabilities, centimeter-wavelength radio astronomy is currently in a renaissance leading up to the advent of the Square Kilometre Array (SKA). The sensitivity upgrades of both the NRAO Very Large Array (VLA) and the Very Long Baseline Array (VLBA) have begun to provide us with a much improved perspective on stellar centimeter radio emission, particularly concerning young stellar objects (YSOs) and ultracool dwarfs. For the first time we now have systematic access to the radio time domain. I will mainly present a deep VLA and VLBA radio survey of the Orion Nebula Cluster (ONC), where we have found hundreds of compact radio sources, a sevenfold increase over previous studies, and intricate detail on the radio emission of proplyds. We can now better disentangle thermal and nonthermal radio emission by assessing spectral indices, polarization, variability, and brightness temperatures (VLBA). With simultaneous radio-X-ray time domain information (Chandra), this project is providing first constraints on YSO radio flares and their relation with X-ray flares, as well as improved constraints on the overall high-energy irradiation of their surroundings, including protoplanetary disks. Starting with Orion, I will additionally discuss the use of the VLBA for precision stellar astrometry in the Gaia era, highlighting how VLBI astrometry is allowing us to extend the Gaia sample of YSOs and ultracool dwarfs by including embedded objects, distant obscured sources in the Galactic plane, and faint ultracool dwarfs, while providing important opportunities for astrometric cross-calibration.

Incorniciare la spiegazione astronomica in spazi emozionali – La divulgazione di argomenti astrofisici mediante fumetti. A. Adamo (INAF)
Nov 13 @ 15:30 – 17:00

Abstract. Negli ultimi anni, in corrisondenza di un certo rinnovato interesse per il medium fumetto e il suo uso con scopi didattici e divulgativi, sono stato coinvolto in progetti di vari committenti, tra i quali anche molti enti di ricerca scientifica (INAF, INFN, EVN, MAS, EUCLID, …), per produrre brevi storie che spiegassero l’astronomia a diverse tipologie di pubblico.

Al variare del committente e del suo pubblico di riferimento, ho dovuto quindi differenziare le strategie comunicative volte a coniugare al meglio le esigenze didattico-divulgative con altre di semplice vendibilità, nel caso di riviste e quotidiani, o, nel caso di enti scientifici, di promozione delle attività di ricerca.

I lavori già prodotti e quelli ai quali sto lavorando hanno così assunto vari caratteri: alcune storie sono di carattere storico, altre ne hanno uno più tecnico, altre ancora invece fanno leva sulla comunicazione emozionale nella quale il messaggio scientifico risulta piacevolmente diluito, sotterraneo, apparentemente secondario.

Per il pubblico dell’INSAP e del SEAC ho pensato di descrivere nel mio talk le linee generali delle strategie che ho via via adottato, soffermandomi in particolar modo sulla collaborazione con l’ente cileno Millenium de Astrofisica (M.A.S., http://www.astrofisicamas.cl) per il quale ho prodotto 8 brevi storie nelle quali spiego a fumetti altrettanti argomenti di astrofisica.

Il frame teorico nel quale una simile attività si colloca è quello oramai largamente studiato dei cosiddetti “concept comics”. Si tratta di un serio studio che affonda le sue basi nella epistemologia e nella sociologia della scienza e teso a mettere in luce i pro e i contro di un uso consapevole dei fumetti come strumenti per progettare una didattica e una divulgazione che siano al contempo scientificamente corrette e coinvolgenti così da obbedire ai precetti teorici del cosiddetto engagment, ultima frontiera in ambito pedagogico.
