Interpreting the scattering surface in protoplanetary disks
Massimiliano Bolchini, Giovanni Rosotti, Marion Villenave +5
In recent years, extreme adaptive optics have enabled high-resolution, high-contrast scattered-light observations of protoplanetary disks. Interpreting these observations requires…
Substructures in Planet-Forming Disks with the SKAO
Yinhao Wu, Jessica Speedie, Sebastián Pérez +33
Disks of gas and dust orbiting young stars are the arenas and material reservoirs for planet formation. Over the past decade, multiwavelength observations, from infrared to radio,…
Dust characterization of halos: The extended emission in protoplanetary disks
Sreejita Das, Enrique Macías, Nicolas T. Kurtovic +3
Extended low surface brightness emission has been identified in a number of protoplanetary disks, in tension with predictions of radial drift theory. We aim to investigate the natu…
Grain growth in protoplanetary disks in the Upper Scorpius revealed by millimeter-wave spectral indices
Tau Bito, Akimasa Kataoka, Takahiro Ueda +3
The measurement of dust size from millimeter-wavelength spectra provides direct constraints on grain growth in protoplanetary disks. The spectral indices between 0.88 mm and 2.9 mm…
Detailed Microwave Continuum Spectra from Bright Protoplanetary Disks in Taurus
Caleb Painter, Sean M. Andrews, Claire J. Chandler +9
We present new observations that densely sample the microwave (4-360 GHz) continuum spectra from eight young systems in the Taurus region. Multi-component, empirical model prescrip…
Kinematical signatures: Distinguishing between warps and radial flows
A. Zuleta, T. Birnstiel, R. Teague
Increasing evidence shows that warped disks are common, challenging the methods used to model their velocity fields. Molecular line emission of these disks is characterized by a tw…
Spirals, rings, and vortices shaped by shadows in protoplanetary disks: from radiative hydrodynamical simulations to observable signatures
Alexandros Ziampras, Cornelis P. Dullemond, Tilman Birnstiel +2
Numerous protoplanetary disks exhibit shadows in scattered light observations. These shadows are typically cast by misaligned inner disks and are associated with observable structu…
VLT/MUSE detection of accretion-ejection associated with the close stellar companion in the HT Lup system
Sebastián Jorquera, Mickaël Bonnefoy, Laura M. Pérez +14
The accretion/ejection processes in T-Tauri stars are fundamental to their physical evolution, while also impacting the properties and evolution of the circumstellar material at a…
VLA observations of the disk around the young brown dwarf 2MASS J044427+2512
L. Ricci, H. Rome, P. Pinilla +3
We present multi-wavelength radio observations obtained with the VLA of the protoplanetary disk surrounding the young brown dwarf 2MASS J04442713+2512164 (2M0444) in the Taurus sta…
Direct imaging of the water snow line at the time of planet formation using two ALMA continuum bands
Andrea Banzatti, Paola Pinilla, Luca Ricci +3
Molecular snow lines in protoplanetary disks have been studied theoretically for decades because of their importance in shaping planetary architectures and compositions. The water…
C/O and Snowline Locations in Protoplanetary Disks: The Effect of Radial Drift and Viscous Gas Accretion
Ana-Maria A. Piso, Karin I. Oberg, Tilman Birnstiel +1
The C/O ratio is a defining feature of both gas giant atmospheric and protoplanetary disk chemistry. In disks, the C/O ratio is regulated by the presence of snowlines of major vola…
Lopsided dust rings in transition disks
T. Birnstiel, C. P. Dullemond, P. Pinilla
Context. Particle trapping in local or global pressure maxima in protoplanetary disks is one of the new paradigms in the theory of the first stages of planet formation. However, fi…
Breaking through: The effects of a velocity distribution on barriers to dust growth
Fredrik Windmark, Til Birnstiel, Chris Ormel +1
It is unknown how far dust growth can proceed by coagulation. Obstacles to collisional growth are the fragmentation and bouncing barriers. However, in all previous simulations of t…
Trapping dust particles in the outer regions of protoplanetary disks
P. Pinilla, T. Birnstiel, L. Ricci +4
In order to explain grain growth to mm sized particles and their retention in outer regions of protoplanetary disks, as it is observed at sub-mm and mm wavelengths, we investigate…
Dust size distributions in coagulation/fragmentation equilibrium: Numerical solutions and analytical fits
T. Birnstiel, C. W. Ormel, C. P. Dullemond
Context. Grains in circumstellar disks are believed to grow by mutual collisions and subsequent sticking due to surface forces. Results of many fields of research involving circums…
Testing the theory of grain growth and fragmentation by millimeter observations of protoplanetary disks
T. Birnstiel, L. Ricci, F. Trotta +7
Context. Observations at sub-millimeter and mm wavelengths will in the near future be able to resolve the radial dependence of the mm spectral slope in circumstellar disks with a r…
