Revealing the mid-infrared emission structure of IRAS 16594-4656 and IRAS 07027-7934
D. A. Garcia-Hernandez, A. Manchado, P. Garcia-Lario +3
TIMMI2 diffraction-limited mid-infrared images of a multipolar proto-planetary nebula IRAS 16594-4656 and a young [WC] elliptical planetary nebula IRAS 07027-7934 are presented. Th…
Why are massive O-rich AGB stars in our Galaxy not S-stars?
D. A. Garcia-Hernandez, P. Garcia-Lario, B. Plez +4
We present the main results derived from a chemical analysis carried out on a large sample of galactic O-rich AGB stars using high resolution optical spectroscopy (R~40,000-50,000)…
A search for planetary-mass objects and brown dwarfs in the Upper Scorpius association
M. T. Costado, V. J. S. Bejar, J. A. Caballero +3
We report the results of a deep photometric search for planets and brown dwarfs in the nearby young OB Upper Scorpius association. We obtained optical (I) and near-infrared (JKs) i…
