Drift-dominated dust evolution. A multiwavelength analysis of dust rings in CY Tau and DoAr25
Anastasia Topalidou, Nienke van der Marel, Paola Pinilla +3
Context. Protoplanetary disks are the birthplaces of planets, and understanding the distribution and evolution of dust within them is essential for tracing the early stages of plan…
Gaps and Rings: A Near-Universal Trait of Extended Protoplanetary Discs
Quincy Bosschaart, Osmar M. Guerra-Alvarado, Nienke van der Marel +1
Substructures such as rings, gaps, and cavities are commonly observed in protoplanetary discs and are thought to play a key role in dust evolution and planet formation. However, a…
Molecular line emission from 1000 au scales outflows to <30 au compact structures in NGC1333 IRAS4A2
Osmar M. Guerra-Alvarado, N. van der Marel, P. Nazari +6
Aims. Studying protostellar objects in their earliest stages, particularly during the Class 0 phase, provides key insight into the beginnings of planet formation and dust evolution…
Observational Constraints on Evolution of Dust Disc Properties in Upper Scorpius
Paola Pinilla, Anibal Sierra, Nicolas T. Kurtovic +8
Protoplanetary discs in the Upper Scorpius star-forming region are excellent laboratories to investigate late stages of planet formation. In this work, we analyse the morphology of…
Multi-Wavelength Dust Characterization of the HL Tau Disk and Implications for Planet Formation
Takahiro Ueda, Sean M. Andrews, Carlos Carrasco-González +4
We present a comprehensive analysis of the HL Tau dust disk by modeling its intensity profiles across six wavelengths (0.45 to 7.9 mm) with a resolution of 0.05 arcsec ( au)…
A high-resolution survey of protoplanetary disks in Lupus and the nature of compact disks
Osmar M. Guerra-Alvarado, Nienke van der Marel, Jonathan P. Williams +4
Most of the exoplanets discovered in our galaxy to date orbit low-mass stars, which tend to host small disks in their early stages. To better elucidate the link between planet form…
Rocky planet formation in compact disks around M dwarfs
M. Sanchez, N. van der Marel, M. Lambrechts +2
Rocky planets in compact configurations are the most common ones around M dwarfs. Many disks around very low mass stars (between 0.1 and 0.5 M) are rather compact and small…
Into the thick of it: ALMA 0.45 mm observations of HL Tau at 2 au resolution
Osmar M. Guerra-Alvarado, Carlos Carrasco-González, Enrique Macías +7
Aims. To comprehend the efficiency of dust evolution within protoplanetary disks, it is crucial to conduct studies of these disks using high-resolution observations at multiple wav…
Multiple shells driven by disk winds: ALMA observations in the HH 30 outflow
J. A. López-Vázquez, Chin-Fei Lee, M. Fernández-López +3
We present archive Atacama Large Millimeter/Submillimeter Array (ALMA) Band 6 observations of the CO (J=2-1) and CO (J=2-1) molecular line emission of the protostella…
Grain-size measurements in protoplanetary disks indicate fragile pebbles and low turbulence
Haochang Jiang, Enrique Macías, Osmar M. Guerra-Alvarado +1
Recent laboratory experiments have revealed that destructive collisions of icy dust particles may occur at much lower velocities than previously believed. These low fragmentation v…
IRAS4A1: Multi-wavelength continuum analysis of a very flared Class 0 disk
O. M. Guerra-Alvarado, N. van der Marel, J. Di Francesco +7
Understanding the formation of substructures in protoplanetary disks is vital for gaining insights into dust growth and the process of planet formation. Studying these substructure…
Characterizing the dust content of disk substructures in TW Hya
Enrique Macias, Osmar Guerra-Alvarado, Carlos Carrasco-Gonzalez +4
We present Atacama Large Millimeter Array (ALMA) observations of TW Hya at 3.1 mm with milliarcsecond resolution. These new data were combined with archival high angular r…
