The VLT/NaCo large program to probe the occurrence of exoplanets and brown dwarfs at wide orbits-IV. Gravitational instability rarely forms wide, giant planets
Understanding the formation and evolution of giant planets (≥ 1 M Jup) at wide orbital
separation (≥ 5 AU) is one of the goals of direct imaging. Over the past 15 yr, many surveys …

Towards a population synthesis model of self-gravitating disc fragmentation and tidal downsizing II: the effect of fragment–fragment interactions
It is likely that most protostellar systems undergo a brief phase where the protostellar disc is
self-gravitating. If these discs are prone to fragmentation, then they are able to rapidly form …
