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

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

We investigate the morphologies, masses and possible correlations between these two properties for 108 extremely red galaxies (EROs) found in the Groth strip. The photometric data include U, B, F606W, F814W, J, and K_s bands. The EROs were selected on the basis of their extremely red colour, F814W-K_s ≥ 4 and K_s ≤ 21.0. Morphologies are based on a

We present early- and late-time photometric and spectroscopic observations of supernova (SN) 2009hd in the nearby spiral galaxy NGC 3627 (M66). This SN is one of the closest to us in recent years and provides an uncommon opportunity to observe and study the nature of SNe. However, the object was heavily obscured by dust, rendering it unusually

The first scene opens with the music of Shirley Bassey. The astronomer Henrietta Swan Leavitt is writing a diary when visited by the famous CBS reporter Edward Roscoe Murrow. Henrietta is surprised that this American television channel should want to pay such a tribute to her, but she agrees to be interviewed. Annie Jump Cannon, her friend and

The abundance ratios between key elements such as iron and α-process elements carry a wealth of information on the star formation history (SFH) of galaxies. So far, simple chemical evolution models have linked [α/Fe ] with the SFH time-scale, correlating large abundance ratios with short-lived SFH. The incorporation of full spectral fitting to the
