New tools from wave topology for asteroseismology Asteroseismology studies waves in stars and uses them to infer what their internal structure is. Today, hundreds of stars of every kind show oscillations which allowed us to deduce their mass, radius, rotation rate, width of convective zone, etc. Wave topology proposes a new light under which to […]

Detecting Earth-analogs with radial velocities and photometry Abstract: Understanding how planets form and searching for life beyond Earth are two key goals in exoplanet research. To make progress on both fronts, it is crucial to discover Earth analogs. However, detecting them is a major challenge, as their faint signals are difficult to disentangle from astrophysical […]
