In the spring of 2000 we began TMAP (Table Mountain Astrometry Project), a program designed to provide timely astrometric followup of newly discovered near...

Laplacian resonant chains — where astronomical bodies are in mean motion resonance with two or more other bodies — are rare phenomena observed in systems such...

The atmospheric characterisation of multiple exoplanets in the same system can provide a window into the processes that underpinned their formation and...

Small planets with a radius between 1-4 Earth radii are extremely common in the Milky Way but their planetary formation and evolution are not revealed...

In this talk, I present the discovery and characterization of two transiting planets around the bright M1 V star TOI-776 (J=8.5 mag), detected during Sector 10...

Modern astronomic telescopes take advantage of multi-conjugate adaptive optics, in which wavefront sensors play a key role. A single sensor capable of measuring...

We study the evolution of galaxy structure and of the major merger fraction since z ˜ 1 to present in GOODS-S field for MB ≤ -20 and M* ≥ 1010 Msun selected...

An overview over analysis or modelling tools related to the radial velocity and transit methods for exoplanet detection and characterization is given, with over...
