48. Overview of JWST and its GTO programs on star and planet formation (I)

Alessio Caratti o Garatti (for Tom Ray)

Talk

The James Webb Space Telescope (JWST) is due for launch in 2020. Optimized for near to mid-infrared
wavelengths, it is the largest telescope ever put in space. One of the main science drivers is understanding
star and planet formation: thus the study of outflows and disks is central not only to the JWST guaranteed
time program but will also be the focus of many open time proposals. After...

5. Optical imaging of jets with extreme AO systems (I)

Talk

The new generation of instruments equipped with extreme adaptive optics modules has recently started to provide impressive images of structures around young stellar systems at unprecedented angular resolution and contrast.
In this presentation, I will show recent optical images of jets from young stars taken with VLT/SPHERE, in which for the first time we probe angular separations from the...

8. ALMA polarimetric studies of rotating jet/disk systems

Francesca Bacciotti (INAF - OAA)

Talk

We have recently obtained ALMA Band 7 polarimetric data for the young systems DG Tau and CW Tau, for which the rotation properties of jet and disk have been investigated in previous high angular resolution studies. The motivation was to test the models of magneto-centrifugal launch of jets via the determination of the magnetic configuration at the disk surface. Non-spherical dust grains tend...

50. The Sardinia Radio Telescope (I)

Silvia Leurini

27/06/2018, 15:40

In this talk, I will review the current status of the Sardinia Radio Telescope and the near-future technical developments. In particular, I will discuss the new generation receivers and focus on the spectroscopic capabilities of the telescope and on the impact that the SRT could have in the field of star formation .

49. Analysis of high-resolution spectra of young stars: looking for wind signatures (I)

Elisabetta Rigliaco

Slow-winds have been found to be almost ubiquitous around young stars. These winds, together with magnetospheric accretion, are the main players in the evolution and dispersal of protoplanetary disk material, and they can be magnetically or thermally driven. In this contribution I will present a few results obtained combining observations conducted with the high-resolution spectrograph UVES in...

29. The dispersal of planet-forming discs. A new generation of X-ray photoevaporation models

Giovanni Picogna (USM - LMU Munich)

27/06/2018, 17:00

Talk

The modality of disc dispersal is thought to be of fundamental importance to planet formation, yet the responsible mechanism is still largely unconstrained.
Photoevaporation from the central star is currently a promising avenue to investigate, but the models developed to date do not yet have enough predictive power for a piecewise comparison with the observations.
Wind profiles and rates play...

10. GIARPS High-resolution observations of T Tauri stars (GHOST): first results on jet emission

Teresa Giannini (Istituto Nazionale di Astrofisica (INAF))

27/06/2018, 17:20

Talk

T Tauri stars of the Taurus/Auriga star-forming clouds are a paradigmatic sample for star formation studies.
In spite of that, a comprehensive and systematic analysis of the Taurus population with the goal of deriving
all the relevant source parameters with sufficient accuracy, is still missing. To fill this gap we have started
an observational program (GHOST) with the GIARPS@TNG facility....

55. Properties of a Jet from the T Tauri Star TH 28: a Combined Spectroscopic Study With MUSE and X-Shooter

Aisling Murphy

27/06/2018, 17:40

The second generation ESO VLT instruments MUSE and X-Shooter offer valuable tools for examining the structure and origin of jets. MUSE is an integral field spectrograph with a relatively large field of view and a significant spectral range. Thus numerous important forbidden emission lines can be simultaneously studied in a large portion of the jet. X-Shooter is a broadband spectrograph with an...
