Monte Carlo post-processing for radiation hydro simulations of accreting planets in protoplanetary disks
Anton Krieger, Hubert Klahr, Julio David Melon Fuksman +1
This paper is part of a series investigating the observational appearance of planets accreting from their nascent protoplanetary disk (PPD). We evaluate the differences between gas…
Can gap-edge illumination excite spirals in protoplanetary disks? Three-temperature radiation hydrodynamics and NIR image modelling
Dhruv Muley, Julio David Melon Fuksman, Hubert Klahr
The advent of high-resolution, near-infrared instruments such as VLT/SPHERE and Gemini/GPI has helped uncover a wealth of substructure in planet-forming disks, including large, pro…
Three-temperature radiation hydrodynamics with PLUTO: Thermal and kinematic signatures of accreting protoplanets
Dhruv Muley, Julio David Melon Fuksman, Hubert Klahr
In circumstellar disks around young stars, the gravitational influence of nascent planets produces telltale patterns in density, temperature, and kinematics. To better understand t…
Vertical shear instability in two-moment radiation-hydrodynamical simulations of irradiated protoplanetary disks II. Secondary instabilities and stability regions
Julio David Melon Fuksman, Mario Flock, Hubert Klahr
The vertical shear instability (VSI) is a hydrodynamical instability likely to produce turbulence in the dead zones of protoplanetary disks. Various aspects of this instability rem…
Vertical shear instability in two-moment radiation-hydrodynamical simulations of irradiated protoplanetary disks I. Angular momentum transport and turbulent heating
Julio David Melon Fuksman, Mario Flock, Hubert Klahr
We studied the linear and nonlinear evolution of the Vertical Shear Instability (VSI) in axisymmetric models of protoplanetary disks, focusing on the transport of angular momentum,…
Three-temperature radiation hydrodynamics with PLUTO: Tests and applications to protoplanetary disks
Dhruv Muley, Julio David Melon Fuksman, Hubert Klahr
In circumstellar disks around T Tauri stars, visible and near-infrared stellar irradiation is intercepted by dust at the disk's optical surface and reprocessed into thermal infrare…
Thermal instabilities in accretion disks II: Numerical Experiments for the Goldreich-Schubert-Fricke Instability and the Convective Overstability in disks around young stars
Hubert Klahr, Hans Baehr, Julio David Melon Fuksman
The linear stability analysis of a stratified rotating fluid (see paper I) showed that disks with a baroclinic stratification under the influence of thermal relaxation will become…
Protostellar disks subject to infall: a one-dimensional inviscid model and comparison with ALMA observations
Karim Shariff, Uma Gorti, Julio David Melon Fuksman
A new one-dimensional, inviscid, and vertically integrated disk model with prescribed infall is presented. The flow is computed using a second-order shock-capturing scheme. Include…
A multiwavelength analysis of the spiral arms in the protoplanetary disk around WaOph 6
S. B. Brown-Sevilla, M. Keppler, M. Barraza-Alfaro +23
[Full abstract in the paper] In recent years, protoplanetary disks with spiral structures have been detected in scattered light, millimeter continuum, and CO gas emission. The mech…
Self-similarity and power-laws in GRB 190114C
R. Ruffini, Liang Li, R. Moradi +10
Following Fermi and NOT observations, Ruffini et al. (2019b) soon identified GRB 190114C as BdHN I at z=0.424, it has been observed since, with unprecedented accuracy, [...] all th…
On the role of a cavity in the hypernova ejecta of GRB 190114C
R. Ruffini, J. D. Melon Fuksman, G. V. Vereshchagin
Within the binary-driven hypernova I (BdHN I) scenario, the gamma-ray burst GRB190114C originates in a binary system composed of a massive carbon-oxygen core (CO), and a b…
The inner engine of GeV-radiation-emitting gamma-ray bursts
R. Ruffini, J. A. Rueda, R. Moradi +12
We motivate how the most recent progress in the understanding the nature of the GeV radiation in most energetic gamma-ray bursts (GRBs), the binary-driven hypernovae (BdHNe), has l…
On the ultra-relativistic Prompt Emission (UPE), the Hard and Soft X-ray Flares, and the extended thermal emission (ETE) in GRB 151027A
R. Ruffini, L. Becerra, C. L. Bianco +12
We analyze GRB 151027A within the binary-driven hypernova (BdHN) approach, with progenitor a carbon-oxygen core on the verge of a supernova (SN) explosion and a binary companion ne…
On the Casimir interaction between two smoothly deformed cylindrical surfaces
Julio David Melon Fuksman, César Daniel Fosco
We generalize the derivative expansion (DE) approach to the interaction between almost-flat smooth surfaces, to the case of surfaces which are optimally described in cylindrical co…
Early X-ray Flares in GRBs
R. Ruffini, Y. Wang, Y. Aimuratov +17
We analyze the early X-ray flares in the GRB "flare-plateau-afterglow" (FPA) phase observed by Swift-XRT. The FPA occurs only in one of the seven GRB subclasses: the binary-driven…
