We present new intermediate-band Strömgren photometry based on more than 300 u,v,b,y images of the Galactic globular cluster omega Cen p, covering a region of...
Stromgren and infrared photometry of OB candidates in the association Cygnus OB2
The Cygnus OB2 association contains some of the most massive and most luminous O-stars in the northern hemisphere. As a first step toward studying the initial...
Strong lithium lines in red supergiants at different metallicities
Lithium (Li) is a fragile material, easily destroyed in stellar interiors. Within our current understanding of stellar evolution for stars more massive than $...
Strong lithium lines in red supergiants at different metallicities
Current models of stellar evolution predict that stars more massive than ∼6 M ⊙ should have completely depleted all lithium (Li) in their atmospheres by the...
Strong Size Evolution of the Most Massive Galaxies since z˜ 2
We explore the size evolution of 831 very massive galaxies (Mstar≥1011 h70-2 Msun) since z˜ 2 using the combined capabilities of the large near infrared Palomar...
Structural analysis for the EST preliminary design specifications
This contribution presents the structural analysis that followed the preliminary design specifications of the European Solar Telescope (EST). EST is a 4-metre...
This paper shows the different design concepts and techniques employed in the structural and thermal analysis of EMIR (Espectrografo Multiobjeto Infrarrojo)...
