SUMMARY:Inferring past accretion bursts from asteroseismic imprints
DESCRIPTION:Recording: https://www.oact.inaf.it/seminars/ \nDATE: Monday\, February 23\, 11:30 a.m. \nORGANIZER: INAF-OACT \nLOCATION: AULA OVEST (INAF-OACT) + remote \nLink for the remote audience:https://meet.google.com/wvf-uwxo-oyj \nSPEAKER:Johannes Jørgensen (Innsbruck University) \nABSTRACT:Stars form during the collapse of dense molecular cloud cores. However\, most of their final mass comes from the ensuing protostellar disk\, owing to non-zero angular momentum in the cloud. Here\, the protostar gains up to 50% of its final mass in episodic bursts of mass accretion\, while having quiescent phases between the bursts. In this presentation I present a study of how the occurrence of such bursts may be inferred using asteroseismology – the study of stellar pulsations. Specifically\, I show how these intense episodes leave a detectable asteroseismic imprint in the deep stellar interior. \n  \nA few rules:— before joining\, make sure you are using your institutional inaf.it account if you have one (otherwise we will grant you permission to join)— please do not forget to mute your microphone and switch off your webcam when access the virtual room— for questions leave a message in the chat\, the answers at the end of the webinar— the seminar will be recorded\, so if you are interested in it\, please contact us to get the link to the registration.

SUMMARY:L’Office of Astronomy for Education Center Italy: che cosa è\, che cosa fa e perché lo fa in quel modo.
DESCRIPTION:Recording: https://www.oact.inaf.it/seminars/ \nDATE: Tuesday\, February 24\, 11:15 a.m. \nORGANIZER: INAF-OACT \nLOCATION: AULA OVEST (INAF-OACT) + remote \nLink for the remote audience:https://meet.google.com/wvf-uwxo-oyj \nSPEAKER: Stefano Sandrelli (INAF O.A. Brera) \nABSTRACT:Fondato nel marzo 2021\, l’Office of Astronomy for Education Center Italy (I-OAE) è un ufficio internazionale della IAU\, coordinato e finanziato da INAF. I-OAE promuove e sostiene pratiche di insegnamento innovativo\, centrato sulla persona\, e di corsi di formazione docenti.Nei suoi primi anni di esistenza\, I-OAE ha sviluppato processi collaborativi\, a cui hanno partecipato rappresentanti di Albania\, Cipro\, Croazia\, Egitto\, Francia\, Grecia\, Israele\, Italia\, Marocco\, Montenegro\, Palestina\, Portogallo\, Slovenia\, Siria\, Spagna e Turchia.  Non solo il network è costante crescita\, ma si sta dimostrando anche di attrarre fondi europei.I-OAE coordina anche l’edizione internazionale di astroEDU\, la piattaforma di attività didattiche peer-reviewed della IAU.I-OAE è un ufficio aperto alla collaborazione di volontari che ne condividano valori e metodi. \n  \nRicordiamo poche regole:— accedere alla virtual room con microfono e telecamera spenti— scrivete eventuali domande nella chat\, a cui verrà data risposta alla fine del webinar— connettersi al webinar utilizzando preferibilmente l’account INAF e il browser Chrome \n

SUMMARY:The EWOCS view of supermassive stellar clusters
DESCRIPTION:Recording: https://www.oact.inaf.it/seminars/ \nDATE: Friday\, February 27\, 11:15 a.m. \nORGANIZER: INAF-OACT \nLOCATION: AULA OVEST (INAF-OACT) + remote \nLink for the remote audience:https://meet.google.com/wvf-uwxo-oyj \nSPEAKER: M. G. Guarcello and the EWOCS Team \nABSTRACT:Star formation in our Galaxy typically occurs in environments less massive than 10^4 solar masses. However\, a few more extreme star forming environments on the Milky Way exist\, where hundreds of thousands to millions of stars form in dense regions. Often called “supermassive star clusters”\, they are rare in our Galaxy today\, while they are common in galaxies experiencing epochs of starburst. The international project EWOCS (Extendend Westerlund 1 and 2 Open Clusters Survey) is targeting the two closest superstar clusters in the Milky Way with a multi-wavelengtht survey which is based on an extensive set of data from radio to X-rays\, with the main objective of studying the formation and early evolution of stars over the whole mass spectrum in a starburst environment.In this talk\, I will discuss the motivations and objectives of the project\, the published results\, ongoing studies and the future developments. \n  \nA few rules:— before joining\, make sure you are using your institutional inaf.it account if you have one (otherwise we will grant you permission to join)— please do not forget to mute your microphone and switch off your webcam when access the virtual room— for questions leave a message in the chat\, the answers at the end of the webinar— the seminar will be recorded\, so if you are interested in it\, please contact us to get the link to the registration. \n
