Direct imaging has revolutionized our view of the substellar population, revealing a growing population of free-floating planets. I will review the first discoveries, the current observational picture, and the prospects opened by upcoming instruments. I will describe the strategies used to identify free-floating planets, combining deep imaging, proper motions, and spectroscopy. Finally, I...
The origins of massive planets seen by direct imaging are uncertain, but these worlds far from their host stars are likely the most vulnerable to ejection in stellar encounters. We have just completed the Planet-Earth Building-Blocks Legacy e-MERLIN Survey (PEBBLeS), which gives the first view of the distribution of small rocks (planetary seeds) in the midplane of massive discs of young stars....
In a recent review paper, we have studied the pre- and proto-brown dwarf (proto-BD) population in different nearby clouds down to the planetary boundary (Palau+2024). Among our findings, we confirm that massive proto-BDs seem to follow the same trends as protostars in different star forming regions. On the other hand, we report an underproduction of low-mass proto-BD candidates in Ophiuchus...
