SPI-ing Exoplanets | Antonio Maggio (INAF/OAPA) @ Palermo
Feb 14 @ 15:30

Star-Planet Interaction (SPI) is a broad phenomenological term which encompasses a variety of physical effects relevant for the evolution of extra-solar planetary systems, in particular for those hosting giant gas planets in close orbits around their parent star. While theoretical expectations of SPI are abundant, observational signatures are still elusive with current instrumentation and adopted observing strategies. I will review the state of the art on the matter, and possible future developments that may help us for a better characterization of exoplanets and their abitability conditions.

Supernova remnants: on new ways to understand the cosmic ray physics | Oleh Petruk, INAF-Osservatorio Astronomico di Palermo
Mar 2 @ 15:30 – 16:30

I will talk about two new possibilities to analyse the observational data on non-thermal emission of cosmic rays accelerated in supernova remnants (SNRs). The first one is related to the polarization images of SNRs. In fact, the polarized radio emission has been mapped with great detail in several Galactic supernova remnants, but has not yet been exploited to the extent it deserves. We have developed a method to model maps of the Stokes parameters for shell-like SNRs during their Sedov evolution phase. The second result bases on the time-dependent particle acceleration and relates the temporal evolution of the radio spectral index of SNR in the aftermath of the explosion to the gamma-ray spectrum at later stages. As a test case, we apply our method to describe gamma-rays from IC443; as a proxy of the IC443 parent supernova we consider SN1987A.

Flaring star-disk magnetic channels in Orion star-forming region | Fabio Reale, Universita’ di Palermo
Mar 8 @ 16:00 – 17:00

It is debated whether the long and intense flares observed on the PMS stars in Orion involve single and very long magnetic channels or much flatter loop arcades. This question is important because the long flaring channels may be so long as to connect the star to the circumstellar disk. In this work a new method solves the question …. (suspence is left on purpose).

SEMINARIO: “The Eastern Edge of the Kappa Ori cluster” – Ignazio Pillitteri (INAF Osservatorio Astronomico di Palermo)

SEMINARIO: "The Eastern Edge of the Kappa Ori cluster" - Ignazio Pillitteri (INAF Osservatorio Astronomico di Palermo)
ABSTRACT:
Orion is a forgery of young stars, composed of several groups and associations that span different ages  (1-15 Myr) distances (350-450 pc) and masses (from BDs to O type stars). X-rays can be used to infer distances of groups of young stars and thus the spatial structure of the Orion complex.  Exploring the synergy of IR and X-ray observations, I present the first results from a recent XMM observation of a group
of young stellar objects around V1818 Ori. This is a follow up devoted to explore the eastern edge of a ring of dust around Kappa Ori(a B0 V star) that embeds groups of YSOs to the west of the star itself. My preliminary analysis shows that also the group of V1818 Ori belongs to  the Kappa Ori cluster at 250 pc and is unrelated to the Mon R2 region to which it has been associated so far.

Seminario Ufficio Comunicazione INAF Roma
Jun 8 @ 11:00 – 16:30

8 giugno ore 11.00  Seminario D. Coero Borga e S. Parisini La struttura di Comunicazione dell’INAF

Come sapete da maggio 2016 l’Inaf ha formalizzato una nuova struttura dedicata alla comunicazione. Com’è organizzata? Chi ci lavora? Cosa si intende per press release, news, conferenza stampa, embargo, comunicato congiunto, virgolettato e cose simili? A chi serve? E, soprattutto, perché parlano di qualunque cosa tranne che delle mie ricerche? Nel corso della prima parte di questo incontro, dedicata a tutti ma in particolare a ricercatrici e ricercatori (precari e non, dai laureandi agli associati già in pensione) tenteremo di soddisfare queste e altre curiosità e dubbi su due dei quattro compiti della struttura di comunicazione: ufficio stampa e Media Inaf. E di raccogliere i vostri suggerimenti. L’obiettivo è migliorare la comunicazione interna, riducendo al minimo i fraintendimenti e cercando di rendere il più possibile serene – magari perfino divertenti – le occasioni d’interazione con noi.
8 giugno ore 14.30 Seminario D. Coero Borga e S. Parisini Utilizzo di videocamera per la produzione di materiale multimediale

Il pomeriggio è dedicato ad una parte più tecnica – rivolta a chiunque ne abbia voglia ma in particolare a chi è interessato a produrre materiale multimediale (perlopiù video) per l’ufficio stampa, Media Inaf e Inaf-Tv – durate la quale daremo qualche rudimento sulle riprese video e faremo qualche simulazione d’intervista. Simulazioni che non verranno messe in rete, promesso: dunque massimo relax e nessun dress code.
