Atmospheric Retrieval of Combined JWST, HST, and Ground-Based Observations Reveals a Featureless Transmission Spectrum for GJ 1132 b
Mohammad Senobar, Sareh Ataiee
We present a panchromatic transmission spectrum of GJ1132b spanning --m, combining published transit observations from Magellan/LDSS3C, HST/WFC3 G141, and JWST/NIRSpe…
Dust continuum radiation maps from MHD simulations of accretion-ejection systems around single and binary stars
Somayeh Sheikhnezami, Christian Fendt, Sareh Ataiee
We study the launching of magnetized jets from a resistive circumstellar disk within a binary system, employing a unique combination of 3D MHD jet launching simulations (PLUTO code…
Overstability of the 2:1 mean motion resonance: Exploring disc parameters with hydrodynamic simulations
Zahra Afkanpour, Sareh Ataiee, Alexandros Ziampras +5
Resonant planetary migration in protoplanetary discs can lead to an interplay between the resonant interaction of planets and their disc torques called overstability. While theoret…
On the effects of photoionization feedback on second-generation star formation in globular clusters of different masses
Asiyeh Yaghoobi, Joakim Rosdahl, Francesco Calura +1
We simulate the formation of second-generation stars in young clusters with masses of and within after the formation of clusters.…
TOI-1130: A photodynamical analysis of a hot Jupiter in resonance with an inner low-mass planet
J. Korth, D. Gandolfi, J. Šubjak +59
The TOI-1130 is a known planetary system around a K-dwarf consisting of a gas giant planet, TOI-1130 c, on an 8.4-day orbit, accompanied by an inner Neptune-sized planet, TOI-1130…
Pushing planets into an inner cavity by a resonant chain
S. Ataiee, W. Kley
Context. The orbital distribution of exoplanets indicates an accumulation of super-Earth sized planets close to their host stars in compact systems. When an inward disc-driven migr…
The role of disc torques in forming resonant planetary systems
S. Ataiee, W. Kley
The most accurate method for modelling planetary migration and hence the formation of resonant systems is using hydrodynamical simulations. Usually, the force (torque) acting on a…
The impact of planet wakes on the location and shape of the water iceline in a protoplanetary disk
Alexandros Ziampras, Sareh Ataiee, Wilhelm Kley +2
Context: Planets in accretion disks can excite spiral shocks, and---if massive enough---open gaps in their vicinity. Both of these effects can influence the overall disk thermal st…
1:1 orbital resonance of circumbinary planets
Anna B. T. Penzlin, Sareh Ataiee, Wilhelm Kley
The recent detection of the third planet in Kepler-47 has shown that binary stars can host several planets in circumbinary orbits. To understand the evolution of such systems we ha…
Stability of the co-orbital resonance under dissipation: Application to its evolution in protoplanetary discs
Adrien Leleu, Gavin Coleman, Sareh Ataiee
Despite the existence of co-orbital bodies in the solar system, and the prediction of the formation of co-orbital planets by planetary system formation models, no co-orbital exopla…
The formation of Jupiter by hybrid pebble-planetesimal accretion
Yann Alibert, Julia Venturini, Ravit Helled +8
The standard model for giant planet formation is based on the accretion of solids by a growing planetary embryo, followed by rapid gas accretion once the planet exceeds a so-called…
Metallicity effect and planet mass function in pebble-based planet formation models
Natacha Brügger, Yann Alibert, Sareh Ataiee +1
One of the main scenarios of planet formation is the core accretion model where a massive core forms first and then accretes a gaseous envelope. This core forms by accreting solids…
How much does turbulence change the pebble isolation mass for planet formation?
S. Ataiee, C. Baruteau, Y. Alibert +1
When a planet becomes massive enough, it gradually carves a partial gap around its orbit in the protoplanetary disk. A pressure maximum can be formed outside the gap where solids t…
Scattered light images of spiral arms in marginally gravitationally unstable discs with an embedded planet
A. Pohl, P. Pinilla, M. Benisty +5
Scattered light images of transition discs in the near-infrared often show non-axisymmetric structures in the form of wide-open spiral arms in addition to their characteristic low-…
Gas and dust structures in protoplanetary disks hosting multiple planets
P. Pinilla, M. de Juan Ovelar, S. Ataiee +4
Transition disks have dust-depleted inner regions and may represent an intermediate step of an on-going disk dispersal process, where planet formation is probably in progress. Rece…
Planet-vortex interaction:How a vortex can shepherd a planetary embryo
S. Ataiee, C. P. Dullemond, W. Kley +2
Context: Anticyclonic vortices are considered as a favourable places for trapping dust and forming planetary embryos. On the other hand, they are massive blobs that can interact gr…
