A highly non-keplerian protoplanetary disc spiral structure in the gas disc of CQ tau
(EDP Sciences, 2021)
Context. In recent years high-angular-resolution observations have revealed that circumstellar discs appear in a variety of shapes with diverse substructures being ubiquitous. This has given rise to the question of whether ...
Cavity and other radial substructures in the disk around HD 97048
(EDP Sciences, 2017)
Context. Gaps, cavities, and rings in circumstellar disks are signposts of disk evolution and planet-disk interactions. We follow the recent suggestion that Herbig Ae/Be disks with a flared disk harbor a cavity, and ...
No evidence of the planet orbiting the extremely metal-poor extragalactic star HIP 13044
(ESO, 2014)
Context. The recent discovery of three giant planets orbiting the extremely metal-poor stars HIP 11952 and HIP 13044 have challenged
theoretical predictions of the core-accretion model. According to this, the metal content ...
Annular substructures in the transition disks around LkCa 15 and J1610
(EDP Science, 2020)
We present high-resolution millimeter continuum ALMA observations of the disks around the T Tauri stars LkCa 15 and 2MASS J16100501-2132318 (hereafter, J1610). These transition disks host dust-depleted inner regions, which ...
Resolved carbon monoxide observations of protoplanetary discs in ophiuchus
(Universidad de Chile, 2022)
The $^{12}$CO rotational lines in protoplanetary discs are good tracers of the total spatial extension of the gas component and potentially planet-disc interactions. This work analyses ALMA long-baseline observations of ...
FARGO3D: A new GPU-oriented MHD code
(IOP Publishing, 2016-03)
We present the FARGO3D code, recently publicly released. It is a magnetohydrodynamics code developed with special emphasis on the physics of protoplanetary disks and planet-disk interactions, and parallelized with MPI. The ...
Spiral Arms in the Disk of HD 142527 from CO Emission Lines with ALMA
(2014-04-10)
In view of both the size of its gap and the previously reported asymmetries and near-infrared spiral arms, the
transition disk of the Herbig Fe star HD 142527 constitutes a remarkable case study. This paper focuses on ...
Planet Formation Signposts: Observability of Circumplanetary Disks Via Gas Kinematics
(IOP, 2015)
The identification of on-going planet formation requires the finest angular resolutions and deepest sensitivities
in observations inspired by state-of-the-art numerical simulations. Hydrodynamic simulations of ...
Physical conditions and kinematics in protoplanetary disks through line emission
(Universidad de Chile, 2019)
Planetary Sciences are constantly progressing. Current facilities have allowed the discovery of a considerable amount of exoplanets and a more detailed study of protoplanetary disks, which is where planets are thought to ...
