11. Rotating molecular cavities scrutinized by ALMA: what can they tell us about magnetic fields in protoplanetary disks ?

Powerful atomic jets and molecular outflows are observed in young protostars at all stages of active accretion, from the young embedded Class 0 and Class 1 phases to the later optically revealed T Tauri or Class 2 phase. The origin of the ejection, its role in angular momentum extraction and impact on protoplanetary disk evolution remain as fundamental open questions in star formation. ...

7. Connection between jets, winds and accretion in T Tauri stars

Brunella Nisini (INAF Osservatorio di Roma)

22/05/2018 14:30

I will present a survey of forbidden line emission in a sample of 130 T Tauri stars in the Lupus, Chamaeleon and sigma Ori clouds conducted with the X-shooter instrument. The aim of the survey is to study the occurrence of high velocity jets and slow winds on a statistical bases, and investigate on the connection between the different mass loss phenomena and the source accretion properties.

10. Jets and Outflows from the UWISH2 Survey

Dr Dirk Froebrich (University of Kent)

22/05/2018 15:00

The talk will present the main results from the UK Wide-field Infrared survey for H2 (UWISH2).

13. ANALYSIS OF THE PHYSICAL PROPERTIES OF JETS/OUTFLOWS IN T TAURI STARS

Mme Fatima Lopez-Martinez (Instituto de Astrofísica e Ciências do Espaço)

22/05/2018 15:30

Winds and jets are key factors in the evolution of accretion disks in pre-main sequence stars, and deriving their physical properties is one of the most important steps for a full understanding of the connection among outflow, jet and accretion processes. In this work we determine the physical properties of the high velocity component (HVC) and the low velocity component (LVC) emitting region...

9. Accretion bursts from young stars

Jochen Eislöffel (Thüringer Landessternwarte)

We will present new observations from accretion bursts from young stars.

29. Jet precession and synchronous outbursts in the binary (triple?) protostar SVS13A

The role of multiplicity and close stellar encounters in accretion and ejection bursts in young stars is a debated issue (Reipurth et al. 2014; Audard et al. 2014, and references therein). An interesting target of study in this context is SVS 13A, a 0.3'' (70 au) binary solar-type protostar (VLA4A,VLA4B; Anglada et al. 2000) with multiple signs of ejection bursts. SVS 13A is the candidate...

34. The Musca molecular cloud: An interstellar symphony

Dr Aris Tritsis (Research School of Astronomy and Astrophysics)

23/05/2018 11:45

Molecular clouds are the birthplaces of stars. Their structure and evolution hold the key to understanding the initial conditions of star and planet formation, and the physics that sets the distribution of masses and multiplicities of newborn stars. However, their complexity, their typically turbulent, filamentary, disordered appearance, and ubiquitous projection effects hinder all efforts to...
