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…
-band photometry of the Extreme T Subdwarf CWISE J221706.28145437.6
Jerry Jun-Yan Zhang, Nicolas Lodieu, Eduardo L. Martín
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…
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…
