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…
Disk fraction among free-floating planetary-mass objects in Upper Scorpius
Tommy Rodrigues, Hervé Bouy, Sean N. Raymond +9
Free-floating planetary-mass objects (FFPs) have been detected through direct imaging in several young, nearby star-forming regions. The properties of circumstellar disks around th…
TOI-1438: A rare system with two short-period sub-Neptunes and a tentative long-period Jupiter-like planet orbiting a K0V star
Carina M. Persson, Emil Knudstrup, Ilaria Carleo +44
We present the detection and characterisation of the TOI-1438 multi-planet system discovered by TESS. We collected a series of follow-up observations including high-spectral resolu…
Euclid: The potential of slitless infrared spectroscopy: A z=5.4 quasar and new ultracool dwarfs
E. Bañados, V. Le Brun, S. Belladitta +226
We demonstrate the potential of Euclid's slitless spectroscopy to discover high-redshift (z>5) quasars and their main photometric contaminant, ultracool dwarfs. Sensitive infrared…
-band photometry of the Extreme T Subdwarf CWISE J221706.28145437.6
Jerry Jun-Yan Zhang, Nicolas Lodieu, Eduardo L. MartÃn
We present deep -band imaging of the extreme T subdwarf CWISE J221706.28145437.6. Using the new photometry, we construct its spectral energy distribution and find this obje…
