The Gaia-ESO Survey: Chromospheric Emission, Accretion Properties, and Rotation in Velorum and Chamaeleon I
A. Frasca, K. Biazzo, A. C. Lanzafame +33
We use the fundamental parameters delivered by the GES consortium in the first internal data release to select the members of Vel and Cha I among the UVES and GIRAFFE spectrosc…
Empirical determination of Einstein A-coefficient ratios of bright [Fe II] lines
T. Giannini, S. Antoniucci, B. Nisini +6
The Einstein spontaneous rates (A-coefficients) of Fe^+ lines have been computed by several authors, with results that differ from each other up to 40%. Consequently, models for li…
Magnetohydrodynamic modeling of the accretion shocks in classical T Tauri stars: the role of local absorption on the X-ray emission
R. Bonito, S. Orlando, C. Argiroffi +5
We investigate the properties of X-ray emission from accretion shocks in classical T Tauri stars (CTTSs), generated where the infalling material impacts the stellar surface. Both o…
The Gaia-ESO Survey: Extracting diffuse interstellar bands from cool star spectra, DIB-based interstellar medium line-of-sight structures at the kpc scale
L. Puspitarini, R. Lallement, C. Babusiaux +26
We study how diffuse interstellar bands (DIBs) measured toward distance-distributed target stars can be used to locate dense interstellar (IS) clouds in the Galaxy and probe a line…
Accretion-ejection connection in the young brown dwarf candidate ISO-Cha1 217
E. T. Whelan, J. M. Alcala, F. Bacciotti +7
As the number of observed brown dwarf outflows is growing it is important to investigate how these outflows compare to the well studied jets from young stellar objects. A key point…
The Gaia-ESO Survey: metallicity of the Chamaeleon I star forming region
L. Spina, S. Randich, F. Palla +37
Context. Recent metallicity determinations in young open clusters and star-forming regions suggest that the latter may be characterized by a slightly lower metallicity than the Sun…
