Proxima Centauri is an M dwarf approximately 15,000 AU from the Alpha Centauri binary, comoving and likely in a loosely bound orbit.

Young stars are often surrounded by dense, rotating discs of gas and dust, known as protoplanetary discs, from which planets are born.

We present 1.3 mm observations of the Sun-like star τ Ceti with the Atacama Large Millimeter/submillimeter Array (ALMA) that probe angular scales of ∼1'' (4 AU).

The detection of anomalies in gravitational microlensing events is nowadays one of the main goals among the microlensing community.
