Euclid Early Release Observations of the Barnard 30 dark cloud I. Brown dwarfs and planetary mass candidate members at the core of the association
D. Barrado, H. Bouy, E. L. Martin +8
This study aims to identify very low-mass members within the Barnard 30 dark cloud, with a particular focus on detecting objects in the substellar domain, including those within th…
Estimating the Luminosities of Protostars with Limited Infrared Photometry
Michael M. Dunham, Aina Palau, Nuria Huélamo +3
The luminosities of protostars provide one of the only indirect methods of measuring their masses and mass accretion rates in their earliest stages of evolution. Accurate measureme…
IRAM 04191+1522: a compact proto-brown dwarf binary candidate
N. Huélamo, I. de Gregorio-Monsalvo, Aina Palau +12
Very low-luminosity objects in nearby star-forming regions have been identified as promising proto-brown dwarf candidates. The study of their multiplicity can shed light on the dom…
Astrometric view of companions in the inner dust cavities of protoplanetary disks
Miguel Vioque, Richard A. Booth, Enrico Ragusa +16
Protoplanetary disks with inner dust cavities (often referred to as "transition disks") are potential signposts of planet formation. We use Gaia astrometry to search for planetary…
Multiplicity of young isolated planetary mass objects in Taurus and Upper Scorpius
H. Bouy, G. Duchêne, G. Strampelli +12
Free-floating planetary mass objects--worlds that roam interstellar space untethered to a parent star--challenge conventional notions of planetary formation and migration, but also…
Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake. How do Planetary Systems Form?
I. MendigutÃa, N. Huélamo, I. Jiménez-Serra +32
The detection and characterization of protoplanets in protoplanetary disks around young stars is emerging as a transformative field that will redefine our understanding of how plan…
