Two inner dust clumps in PDS 70. A third protoplanet traced by trojan material or a substructured inner disk?
O. Balsalobre-Ruza, V. Christiaens, N. Huélamo +21
The PDS 70 cavity hosts two confirmed directly imaged protoplanets and a third inner planet candidate at 13au, labeled PDS 70 d. Despite its Keplerian motion, its unusually blue sp…
Substellar candidates at the earliest stages: the SUCANES database
A. M. Pérez-GarcÃa, N. Huélamo, A. GarcÃa-López +11
Brown dwarfs are the bridge between low-mass stars and giant planets. One way of shedding light on their dominant formation mechanism is to study them at the earliest stages of the…
Euclid: Early Release Observations -- A glance at free-floating new-born planets in the sigma Orionis cluster
E. L. MartÃn, M. {Ž}erjal, H. Bouy +175
We provide an early assessment of the imaging capabilities of the Euclid space mission to probe deeply into nearby star-forming regions and associated very young open clusters, and…
Gas, not dust: Migration of TESS/Gaia hot Jupiters possibly halted by the magnetospheres of protoplanetary disks
I. MendigutÃa, J. Lillo-Box, M. Vioque +4
(Abridged) The presence of short-period (< 10 days) planets around main sequence (MS) stars has been associated either with the dust-destruction region or with the magnetospheric g…
The AstraLux-TESS high-spatial resolution imaging survey. Search for stellar companions of 215 planet candidates from TESS
J. Lillo-Box, M. Morales-Calderón, D. Barrado +6
Chance-aligned sources or blended companions can cause false positives in planetary transit detections or simply bias the determination of the candidate properties. In the era of h…
