The formation of planets together with that of comets and asteroids occurs within the protoplanetary disk surrounding a Sun-like young star. Consequently, the properties of emerging planets along with their primi-tive atmospheres may be shaped by the chemical composition of the disk.
Nonetheless, one of the most important questions in Astrochemistry and Astrobiology is whether the molecules...
The binary system GG Tau A is observed to have a circumbinary disc with a
dust ring located further out than expected from tidal truncation theory.
Given the binary separation, this large cavity can be explained by relaxing
the assumption of a co-planar disc and instead fit the observations with a
mis-aligned circumbinary disc around an eccentric binary with a wider
semi-major axis. I present...
In recent years, the Atacama Large millimeter/submillimter Array (ALMA) and the Spectro-Polarimetric High-contrast Exoplanet Research (SPHERE) instrument at the VLT have given us high resolution and high sensitivity observations of protoplanetary discs, showing peculiar substructures, such as spirals, gaps and horseshoes. Disc instabilities and planets have been proposed to be responsible for...
