High angular resolution evidence of dust traps from deep ALMA Band 3 observations of LkCa15
Anibal Sierra, Paola Pinilla, Laura Pérez +5
Dust traps are the most promising mechanisms to explain the observed substructures in protoplanetary discs. In this work, we present high-angular resolution (60 mas, 9.4 au)…
Constraints on the physical origin of large cavities in transition disks from multi-wavelength dust continuum emission
Anibal Sierra, Laura M. Pérez, Benjamín Sotomayor +8
The physical origin of the large cavities observed in transition disks is to date still unclear. Different physical mechanisms (e.g., a companion, dead zones, enhanced grain growth…
Hints of planet formation signatures in a large-cavity disk studied in the AGE-PRO ALMA Large Program
Anibal Sierra, Laura M. Pérez, Carolina Agurto-Gangas +19
Detecting planet signatures in protoplanetary disks is fundamental to understanding how and where planets form. In this work, we report dust and gas observational hints of planet f…
Stable semivortex gap solitons in a spin-orbit-coupled Fermi gas
Pablo Díaz, Hugo Molinares, Laura M. Pérez +3
We demonstrate the existence of semivortex (SV) solitons, with vorticities and in the two components, in a two-dimensional (2D) fermionic spinor system under the action of…
A magnetically driven disc wind in the inner disc of PDS 70
Justyn Campbell-White, Carlo F. Manara, Myriam Benisty +10
PDS 70 is so far the only young disc where multiple planets have been detected by direct imaging. The disc has a large cavity when seen at sub-mm and NIR wavelengths, which hosts t…
