VLT/FLAMES spectroscopy of red giant branch stars in the Fornax dwarf spheroidal galaxy
B. Lemasle, T. de Boer, V. Hill +13
Fornax is one of the most massive dwarf spheroidal galaxies in the Local Group. The Fornax field star population is dominated by intermediate age stars but star formation was going…
The variable stellar wind of Rigel probed at high spatial and spectral resolution
O. Chesneau, A. Kaufer, O. Stahl +5
We present a spatially resolved, high-spectral resolution (R=12000) K-band temporal monitoring of Rigel using AMBER at the VLTI. Rigel was observed in the Bracket Gamma line and it…
NGC 1866: a milestone for understanding the chemical evolution of stellar populations in the LMC
A. Mucciarelli, S. Cristallo, E. Brocato +9
We present new FLAMES@VLT spectroscopic observations of 30 stars in the field of the LMC stellar cluster NGC 1866. NGC 1866 is one of the few young and massive globular cluster tha…
High spatial resolution monitoring of the activity of BA supergiant winds
Olivier Chesneau, Luc Dessart, A. Kaufer +4
There are currently two optical interferometry recombiners that can provide spectral resolutions better than 10000, AMBER/VLTI operating in the H-K bands, and VEGA/CHARA, recently…
A high resolution VLT/FLAMES study of individual stars in the centre of the Fornax dwarf spheroidal galaxy
B. Letarte, V. Hill, E. Tolstoy +13
For the first time we show the detailed late-stage chemical evolution history of small nearby dwarf spheroidal galaxy in the Local Group. We present the results of a high resolutio…
Rapid-Response Mode VLT/UVES spectroscopy of GRB060418: Conclusive evidence for UV pumping from the time evolution of FeII and NiII excited- and metastable-level populations
P. M. Vreeswijk, C. Ledoux, A. Smette +11
We present high-resolution spectroscopic observations of GRB060418, obtained with VLT/UVES. These observations were triggered using the VLT Rapid Response Mode (RRM), which allows…
Multi-periodic photospheric pulsations and connected wind structures in HD64760
A. Kaufer, O. Stahl, R. K. Prinja +1
We report on the results of an extended optical spectroscopic monitoring campaign on the early-type B supergiant HD64760 (B0.5Ib) designed to probe the deep-seated origin of spatia…
