A first look at the protoplanet WISPIT 2 b with VLTI/GRAVITY+
GRAVITY+ Collaboration, K. Abd El Dayem, R. Abuter +116
Confirmed observations of young protoplanets actively undergoing the process of formation have remained rare to date. In this Letter, we present new insights into the nature of the…
JWST/MIRI Imaging Search for Kinematically Detected Protoplanetary Candidates
G. Cugno, M. Benisty, R. Teague +32
Kinematic perturbations observed with ALMA in CO line emission provide evidence for a population of embedded giant protoplanets shaping the structure of protoplanetary disks. We pr…
The ESO SupJup Survey XI. Atmospheric properties of six isolated M- and L-type dwarfs with CRIRES+
C. R. Malcolm, N. Grasser, I. A. G. Snellen +9
The distinct formation pathways of brown dwarfs and giant exoplanets may be encoded in their atmospheric composition. We present atmospheric retrievals for six isolated brown dwarf…
Chemistry and Isotope Ratios of Substellar Atmospheres in the Pictoris Young Moving Group and Vicinity
Yurou Liu, Yapeng Zhang, Jerry W. Xuan +7
Measuring the chemical and isotopic compositions of gas giants and brown dwarfs provides insights into their formation pathways and birth environments. 2MASS J0249-0557 c is an L2-…
The carbon isotope ratio of β Pic b with high-resolution spectroscopy
D. González Picos, I. A. G. Snellen, R. Landman +6
Isotopic ratios trace the formation and evolution of planets and link their atmospheres to the chemistry of their natal protoplanetary discs. We measure $^{12}\mathrm{C}/^{13}\math…
Multi-epoch scattered-light analysis of HD 135344B: new evidence for a spiral-driving protoplanet
J. Latour, V. Christiaens, O. Absil +17
The HD 135344B (SAO 206462) disk exhibits strong signposts of planet formation. ALMA images in the sub-mm revealed a gap-crossing dust filament whose position coincides with a twis…
