Chemical abundances in the protoplanetary disk LV2 (Orion) - II: High dispersion VLT observations and microjet properties
ISM – abundances HII regions ISM:stars: pre-main-sequence protostars protoplan- etary disks
2011/9/29
Integral field spectroscopy of the LV2 proplyd is presented taken with the VLT/FLAMES Argus array at an angular resolution of 0.31x0.31 arcsec^2 and velocity resolutions down to 2 km/s per pixel. Foll...

2010/11/9
Context. Palomar 1 is a peculiar globular cluster (GC). It is the youngest Galactic GC and it has been tentatively associated to several of the substructures recently discovered in the Milky Way (MW),...
Chemical abundances in metal-poor giants: limitations imposed by the use of classical 1D stellar atmosphere models
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/29
In this work we have used 3D hydrodynamical (CO5BOLD) and 1D hydrostatic (LHD) stellar atmosphere models to study the importance of convection and horizontal temperature inhomogeneities in stellar abu...
3D hydrodynamical CO5BOLD model atmospheres of late-type giants: chemical abundances from molecular lines
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/28
We investigate the influence of convection on the formation of molecular spectral lines in the atmospheres of late-type giants. For this purpose we use the 3D hydrodynamical CO5BOLD and classical 1D L...
