On the interaction between embedded planets and the corotation region of protoplanetary discs [PDF]

, 2015
PhDDisc material in the corotation region librates with respect to low-mass planets on horseshoe trajectories. The exchange of angular momentum associated with this libration gives rise to the non-linear corotation torque (the horseshoe drag).

TOI-1859b: A 64 Day Warm Jupiter on an Eccentric and Misaligned Orbit

The Astrophysical Journal Letters, 2023
Warm Jupiters are close-in giant planets with relatively large planet–star separations (i.e., 10 < a / R _⋆ < 100). Given their weak tidal interactions with their host stars, measurements of stellar obliquity may be used to probe the initial obliquity ...

Gap formation in a self-gravitating disk and the associated migration of the embedded giant planet [PDF]

, 2014
We present the results of our recent study on the interactions between a giant planet and a self-gravitating gas disk. We investigate how the disk's self-gravity affects the gap formation process and the migration of the giant planet.

Constraining the gas distribution in the PDS 70 disk as a method to assess the effect of planet-disk interactions [PDF]

, 2023
Embedded planets are potentially the cause of substructures like gaps and cavities observed in several protoplanetary disks. Thus, the substructures observed in the continuum and in line emission encode information about the presence of planets in the ...

Star-planet interactions [PDF]

, 2018
When planets are formed from the protoplanetary disk and after the disk has dissipated, the evolution of their orbits is governed by tidal interactions, friction, and gravitational drag, and also by changes in the mass of the star and planet.

Star-planet interactions [PDF]

, 2021
Context. Tidal interactions and planetary evaporation processes impact the evolution of close-in star–planet systems. Aims. We study the impact of stellar rotation on these processes. Methods.

Characterizing circumstellar disk around young stars [PDF]

, 2010
The circumstellar disks play a fundamental role in star and planet formation process. Studies on circumstellar disks are generally carried on following two viable approaches: "statistical" studies, where a large samples of sources are measured to ...

Gas phase ion species released during grain collisions: Implications for protoplanetary disks

Astronomy & Astrophysics
Grain charging and gas ionization are important processes in protoplanetary disks. Both occur in mutual collisions between grains, as charge is exchanged between grain surfaces but also released into the surrounding gas as ions.

Dynamics of the TWA 7 planetary system and possibility of an additional planet

Astronomy & Astrophysics
Context. The debris disk surrounding the young star TWA 7 exhibits morphological features that tightly constrain its planetary architecture. JWST/MIRI observations have recently revealed a directly imaged outer planet orbiting at a large separation.
