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.

The Theroretical Physics theme for the 80th anniversary is "Quantum, Inifinity and Beyond" The events will tie in the main research topics of the School and draw on its rich history. More on DIAS 2020 can be found here: dias.ie/dias2020/
DIAS School of Theoretical Physics is one of the two founding Schools. It's first Director was the renowned Physicist Erwin Schrödinger, and the School can boast a number of other big names in Irish and International physics and mathematics. #DIASdiscovers
DIAS & @esa Solar Orbiter. Professor Peter Gallagher and Dr Shane Maloney worked on the recently launched space mission. dias.ie/2020/02/11/dia… #DIASdiscovers #WeAreAllSolarOrbiters #SolarOrbiter
On 5th February 1943, Nobel Prize-winning physicist, Prof Erwin Schrödinger, then Director of Theoretical Physics at DIAS, delivered the first of his renowned ‘What is Life?’ lectures. He delivered further lectures in his ‘What is Life?’ series over the following month.
@petertgallagher will be on @PatKennyNT at 11.20 talking about the @esa #SolarOrbiter launch that took place at 4.03 yesterday morning from Cape Canaveral. ☀️🛰️ Listen now: newstalk.com #DIASdiscovers
