Is there a carbon-depleted population in the trans-neptunian belt?
Recent results suggest that there is a group of trans-Neptunian objects (TNOs), 2003 EL61 being the biggest member, with similar dynamical and physical...
Is there Any Evidence for Integrated Sachs-Wolfe Signal in WMAP First Year Data?
We introduce a pixel-to-pixel comparison method to detect the temperature anisotropies on the Cosmic Microwave Background induced by the time variation of...
Is There Plenty of Metal-poor Stars with Planets in the Galactic Thick Disk?
We performed an uniform spectroscopic analysis of 1111 FGK dwarfs observed as part of the HARPS GTO planet search program. We applied a purely chemical approach...
Is turbulent convection the only excitation mechanism for solar p-modes?
The turbulent convection zone is now considered as the only known source of the excitation of p-modes in the Sun. In Perez and Roca Cortes (1999) an analysis...
