Asteroids as the parent bodies of meteorites: compositional
Due to their orbits, near-Earth asteroids (NEAs) have been considered the most evident parent bodies of meteorites. Dynamical models show that NEAs come...
While there may be some possibilities of detecting biological signatures (“biomarkers”) outside the Solar System from the ground, most authorities believe that...
Astronomical Site's Characterization in the era of Extremely Large Telescopes: an overview of atmospheric turbulence monitoring for Adaptive Optics performance simulations
In the past years, intensive Site Characterization campaigns have been performed to chose the sites for the future giant ELTs. Various atmospheric turbulence...
Astronomy and ancient Greek cult: new perspectives to Greek religious architecture and cult practices
One of the main contributions that archaeoastronomy —assisted by rigorous methodology— can bring to studies of religious practice, particularly in Greece, is to...
Dark matter makes up most of the mass of the Universe but remains mysterious. I discuss recent progress in constraining its properties by measuring its...
Atmospheric Dynamics in Mira Stars: A Spectropolarimetric Insight
To study the extended atmosphere of evolved stars such as Mira-type variables, spectropolarimetry is an innovative tool. For many kinds of stars, it has been...
