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…
A Tentative Detection of a Point Source in the Disk Gap of HD 100546 with VLT/SPHERE-IRDIS Sparse Aperture Masking Interferometry
Dori Blakely, Doug Johnstone, Tomas Stolker +5
We re-analyze VLT/SPHERE-IRDIS K and H-band sparse aperture masking interferometry data of the transition disk HD 100546 observed in 2018 and 2021, respectively. We fit geometrical…
Observational Signatures of Circumbinary Discs II: Kinematic Signatures in Velocity Residuals
Josh Calcino, Brodie Norfolk, Daniel J. Price +7
Kinematic studies of protoplanetary discs are a valuable method for uncovering hidden companions. In the first paper of this series, we presented five morphological and kinematic c…
Observational Signatures of Circumbinary Discs I: Kinematics
Josh Calcino, Daniel J. Price, Christophe Pinte +5
We present five morphological and kinematic criteria to aid in asserting the binary nature of a protoplanetary disc, based on 3D hydrodynamical simulations of circumbinary discs po…
Kinematic and thermal signatures of the directly imaged protoplanet candidate around Elias 2-24
Christophe Pinte, Iain Hammond, Daniel J. Price +9
We report kinematic and thermal signatures associated with the directly imaged protoplanet candidate in the Elias 2-24 disc. Using the DSHARP ALMA observations of the CO J=2…
The Origin of the Doppler-flip in HD 100546: a large scale spiral arm generated by an inner binary companion
Brodie J. Norfolk, Christophe Pinte, Josh Calcino +9
Companions at sub-arcsecond separation from young stars are difficult to image. However their presence can be inferred from the perturbations they create in the dust and gas of pro…
Mapping the Planetary Wake in HD 163296 with Kinematics
Josh Calcino, Thomas Hilder, Daniel J. Price +4
We map the planetary wake associated with the embedded protoplanet creating the CO kink in the disk of HD~163296. We show that the wake can be traced by a series of correlated pert…
Four new PLanetesimals Around TYpical and Pre-main seqUence Stars (PLATYPUS) Debris Discs at 8.8mm
Brodie J. Norfolk, Sarah T. Maddison, Jonathan P. Marshall +9
Millimetre continuum observations of debris discs can provide insights into the physical and dynamical properties of the unseen planetesimals that these discs host. The material pr…
Dust Traps and the Formation of Cavities in Transition Discs: A millimetre to sub-millimetre comparison survey
Brodie J. Norfolk, Sarah T. Maddison, Christophe Pinte +8
The origin of the inner dust cavities observed in transition discs remains unknown. The segregation of dust and size of the cavity is expected to vary depending on which clearing m…
Discovery of s-process enhanced stars in the LAMOST survey
Brodie J Norfolk, Andrew R Casey, Amanda I Karakas +7
Here we present the discovery of 895 s-process-rich candidates from 454,180 giant stars observed by the Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST) using a d…
On the discovery of K-enhanced and possibly Mg-depleted stars throughout the Milky Way
Alex J. Kemp, Andrew R. Casey, Matthew T. Miles +8
Stars with unusual elemental abundances offer clues about rare astrophysical events or nucleosynthetic pathways. Stars with significantly depleted magnesium and enhanced potassium…
