Astrometric Exomoon Detection By Means Of Optical Interferometry
Context: With no conclusive detection to date, the search for exomoons, satellites of planets orbiting other stars, remains a formidable challenge. Detecting these objects, compiling a population-level sample and constraining […]

A Planetary-mass Candidate Imaged In The Young Suns Exoplanet Survey
Directly imaged exoplanets in wide orbits challenge current gas giant formation theories. They need to form quickly and acquire enough material before the disk dissipates, which cannot be accommodated by […]

Early Accretion of Large Amounts of Solids for Directly-Imaged Exoplanets
As the number of planetary mass objects (PMOs, ⪅13 MJupiter) at wider separation (⪆10 AU) grows, there is emerging evidence that they form differently from their higher-mass brown-dwarf (BD) counterparts.
