The composition of the most primitive solar system condensates, such as calcium-aluminum-rich inclusions (CAIs) and micron-sized corundum grains, show that...

In a recent preprint, Pepper et al. (2002) evaluate the sensitivity of photon-noise limited transit searches for habitable planets. They conclude that these...

Spectroscopic and spectropolarimetric observations with high spectral resolution provide extremely rich information on the physical conditions of distant...

Post Main Sequence (post MS) stars keep a trace of their past main sequence history. Typically, the presence or not of an Intermediate Convective Zone (ICZ)...

High quality observations of the low degree p-modes exist for almost two complete solar cycles using the solar spectrophotometer Mark-I, located and operating...

Once main-sequence (MS) solar-like stars transitioned from the saturated to the unsaturated regime in magnetic activity, their evolution was perceived as...

Very high resolution (R>150,000) spectra of a small sample of nearby K-dwarfs have been acquired to measure the line asymmetries and central wavelength shifts...

Vulcanism was first detected on Io in 1978 by Voyager 1. Since then it has been recognised that Io is the most volcanically active body in the Solar System...

We based on two interferometric modern techniques: Electronic Speckle Pattern Interferometry and Fringe Projection Technique we had realized simulations of...
