Metallicity of low-mass stars in Orion
V. D'Orazi, S. Randich, E. Flaccomio +3
Determining the metal content of low-mass members of young associations provides a tool that addresses different issues, such as triggered star formation or the link between the me…
FLAMES spectroscopy of low-mass stars in the young clusters sigma Ori and lambda Ori
G. G. Sacco, E. Franciosini, S. Randich +1
Aims. We performed a detailed membership selection and studied the accretion properties of low-mass stars in the two apparently very similar young (1-10 Myr) clusters sigma Ori and…
Tracing mixing in stars: new beryllium observations of the open clusters NGC 2516, Hyades, and M67
S. Randich, F. Primas, L. Pasquini +2
Determinations of beryllium abundance in stars, together with lithium, provide a key tool to investigate the so far poorly understood extra-mixing processes at work in stellar inte…
Spot the differences: The X-ray spectrum of SU Aur compared to TW Hya
K. Smith, M. Audard, M. Guedel +2
We present high-resolution Chandra HETGS X-ray spectra of the classical T Tauri star SU Aur. The quiescent X-ray emission is dominated by a 20-40 MK plasma, which contrasts strongl…
A new concept and a preliminary design for a high resolution (HR) and very-high resolution (VHR) spectrograph for the LBT
F. M. Zerbi, P. Spano', P. Conconi +4
A way to fully exploit the large collecting area of modern 8-10m class telescopes is high resolution spectroscopy. Many astrophysical problems from planetary science to cosmology b…
