Aims.We investigate the non-Local Thermodynamic Equilibrium (non-LTE) line formation of neutral carbon in late-type stars in order to remove some of the potential systematic errors in stellar abundance analyses employing C i features. Methods: .The statistical equilibrium code MULTI was used on a grid of plane-parallel 1D MARCS atmospheric models

The Tarantula FLAMES Survey is an ESO Large Program aimed at disentangling the role of binarity in the evolution of massive stars. We have multiepoch, high resolution and SNR observations of about 1000 massive OB stars in 30 Dor secured with the FLAMES spectrograph at VLT. In this poster we present a general view of the project and the main

The use of integral field spectroscopy is since recently allowing to measure the emission line fluxes of an increasingly large number of star-forming galaxies, both locally and at high redshift. Many studies have used these fluxes to derive the gas-phase metallicity of the galaxies by applying the so-called strong-line methods. However, the

The Stellar Observations Network Group (SONG) is an internationalnetwork project aiming to place eight 1 m robotic telescopes around the globe,with the primary objectives of studying stellar oscillations and planetsusing ultra-precision radial velocity measurements.The prototype of SONG will be installed and running at the Observatoriodel Teide by

OmegaWhite is a wide-field, high cadence, synoptic survey targeting fields in the southern Galactic plane, with the aim of discovering short period variable stars. Our strategy is to take a series of 39 s exposures in the g band of a 1 deg2 of sky lasting 2 h using the OmegaCAM wide field imager on the VLT Survey Telescope (VST). We give an
