X-shooter spectroscopy of young stellar objects in Lupus. Accretion properties of class II and transitional objects
The mass accretion rate, Ṁ acc , is a key quantity for the understanding of the physical processes governing the evolution of accretion discs around young low-mass ( M ⋆  ≲ 2.0 M ⊙ ) stars andExpand

Probing the embedded YSOs of the R CrA region through VLT-ISAAC spectroscopy
Near IR spectra at low (R ∼ 800) and medium (R ∼ 9000) resolution, obtained with ISAAC at VLT, have been used to pose constraints on the evolutionary state and accretion properties of a sample ofExpand

POISSON project - I. Emission lines as accretion tracers in young stellar objects: results from observations of Chamaeleon I and II sources
Context. We present the results of the analysis of low-resolution optical-near IR spectroscopy (0.6–2.4 μm) of a sample (47 sources) of Class I and Class II young stellar objects in the Chamaeleon IExpand

The outburst of an embedded low-mass YSO in L1641
Context. Strong outbursts in very young and embedded protostars are rare and not yet fully understood. They are believed to originate from an increase in the mass accretion rate (M acc ) onto theExpand

Accretion and ejection properties of embedded protostars: the case of HH26, HH34, and HH46 IRS
Aims. We present the results of a spectroscopic analysis of three young embedded sources (HH26 IRS, HH34 IRS, and HH46 IRS) belonging to different star-forming regions and displaying well-developedExpand

POISSON project - III - Investigating the evolution of the mass accretion rate
As part of the POISSON project (Protostellar Optical-Infrared Spectral Survey on NTT), we present the results of the analysis of low-resolution NIR spectra 0.9-2.4 um) of two samples of YSOs in LupusExpand

Connection between jets, winds and accretion in T Tauri stars: the X-shooter view
We have analysed the [OI]6300 A line in a sample of 131 young stars with discs in the Lupus, Chamaeleon and signa Orionis star forming regions, observed with the X-shooter spectrograph at VLT. TheExpand

SPHERE / ZIMPOL high resolution polarimetric imager. I. System overview, PSF parameters, coronagraphy, and polarimetry.
We describe the Zurich Imaging Polarimeter (ZIMPOL), the visual focal plane subsystem of the SPHERE "VLT planet finder", which pushes the limits of current AO systems to shorter wavelengths, higherExpand
