Accretion/Ejection Processes in Young Stars: An Interdisciplinary Approach.
Abstract:
I will talk about my research on stellar jets and accretion processes in young stellar objects at INAF – Osservatorio Astronomico di Palermo but also in the context of international collaborations.
I will focus on the multi-band (mainly optical and X-rays) data analysis of the shocks formed at the interaction front between a supersonic jet and the ambient medium, also discussing the physical parameters that can be derived (jet-to-ambient density contrast, location of the optical and X-ray emission, proper motion of the internal knots,…).
I will present the results of the numerical simulations and the tool developed to synthesize from the models the parameters that can be directly compared with the multi-band observations of jets.
Then I will discuss some open issues in the context of accretion process in young stars, discussing a multi-band (optical, UV, and X-rays) analysis of these shocks.
The novelty of our approach is the interdisciplinary method, which combines multi-band observations, numerical models, and laboratory experiments, both for jets and for accretion shocks in young stars.
Future perspectives with next generation instruments (e.g. Athena and Large Synoptic Survey Telescope – LSST) will be discussed.

You're invited to join us for the @StpDias Statutory Public Lecture 2019 on 23 May 2019, 6pm by Prof. Don Zagier in @tcddublin. Prof. Zaigier will deliver an exciting look at 'Numbers, Knots, & Quantum Theory'. Info and tickets at: bit.ly/2JLsAUj #DIASdiscovers
As part of IQF 2019 on 22 May, Prof. Marika Taylor will explain what #BlackHoles might teach us about #QuantumComputing and conversely, what quantum theory implies about the fundamental properties of black holes. Register at bit.ly/2WuKgHo #DIASdiscovers
The annual Irish Quantum Foundations meeting will take place this year in @tcddublin on 23 & 24 May, bringing together Irish and international theoretical physicists who work fundamental theory and quantum foundations. More info and registration at maths.tcd.ie/~tristan/IQF20….
At last week's final #WhatIsLife lecture, Director of @StpDias Professor Werner Nahm contemplated the impact of Ada Yonath's work for the question 'what is life?' and tying into the impact and legacy of #Schrödinger. #DIASdiscovers
Martin Möllhoff, Director of Irish National Seismic Network spoke to @OceanFmIreland about yesterday's earthquake in Donegal. You can lsiten back at: oceanfm.ie/2019/04/30/ano… #DIASdiscovers
On Thursday, Werner Nahm had us 'thinking outside the box' at the fourth and final @DIAS_Dublin 'What is Life?' lecture series. The series commemorated the 75th anniversary of Erwin #Schrödinger's ground breaking series being published as a book. #DIASdiscovers
Another Earthquake recorded in Donegal by the Irish National Seismic Network. Magnitude 2.1. You can read more about it at tinyurl.com/y4bewx3h. #DIASdiscovers twitter.com/dias_geophysic…
If you haven't booked your place at today's lunchtime lecture from the @StpDias, exploring the legacy of Schrödinger’s 'What is Life?' lectures and book, do so now at: bit.ly/2KZStSH It's te final one lecture of the series. #DIASdiscovers
Don't miss the 4th and final lecture in our #WhatisLife series with Prof Werner Nahm, Director of @StpDias, looking at ‘Beyond the ‘What is Life?’ lectures and book’. This lecture, at 1pm tomorrow, will explore the legacy of Professor Erwin Schrödinger. bit.ly/2KZStSH
#DidYouKnow the recent earthquake in Donegal was not the county's first? In fact, they're well used to a tremor or 2.7 in the North West. Read about the county's ground shaking history in The @IrishTimes at: bit.ly/2UTkAHw #DIASdiscovers
#OTD John T. Lewis was born in 1932. Lewis served as Director of @StpDias and was described by @IrishTimes as a 'theoretical physicist who revolutionized telecommunication.' You can read his obituary in the @LondonMathSoc newsletter at: bit.ly/2XeTrvn #DIASdiscovers
