Environmental interactions in Class II systems and their impact on the disk-planet architecture
Pedro P. Poblete, Nicolás Cuello, Tim D. Pearce +4
Protoplanetary disks evolve in clustered environments where interactions with nearby stars and interstellar gas are common. Such environmental processes, including stellar flybys a…
Infall Explains the Disk Kinematics of AB Aur Without Gravitational Instability
Josh Calcino, Daniel J. Price, Chris W. Ormel
Late-stage infall onto protoplanetary disks can produce large scale spiral arms. In this paper we used 3D smoothed particle hydrodynamics and radiative transfer simulations to stud…
Mapping the merging zone of late infall in the AB Aur planet-forming system
Jessica Speedie, Ruobing Dong, Richard Teague +10
Late infall events challenge the traditional view that planet formation occurs without external influence. Here we present deep ALMA CO and SO observ…
Anatomy of a Fall: Stationary and super-Keplerian spiral arms generated by accretion streamers in protostellar discs
Josh Calcino, Daniel J. Price, Thomas Hilder +3
Late-stage infall onto evolved protoplanetary discs is an important source of material and angular momentum replenishment, and disc substructures. In this paper we used 3D smoothed…
Nature vs Nurture: Three Dimensional MHD Simulations of Misaligned Embedded Circum-Single Disks within an AGN Disk
Bhupendra Mishra, Josh Calcino
Stellar mass black holes in the disks around active galactic nuclei (AGN) are promising sources for gravitational wave detections by LIGO/VIRGO. Recent studies suggest this environ…
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…
Runaway Eccentricity Growth: A Pathway for Binary Black Hole Mergers in AGN Disks
Josh Calcino, Adam M. Dempsey, Alexander J. Dittmann +1
Binary black holes embedded within the accretion disks that fuel active galactic nuclei (AGN) are promising progenitors for the source of gravitational wave events detected by LIGO…
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…
A kinematic excess in the annular gap and gas depleted cavity in the disc around HD 169142
Himanshi Garg, Christophe Pinte, Iain Hammond +6
We present ALMA band 6 images of the 12CO, 13CO and C18O J=2-1 line emissions for the circumstellar disc around HD 169142, at ~8 au spatial resolution. We resolve a central gas dep…
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…
External or internal companion exciting the spiral arms in CQ Tau?
Iain Hammond, Valentin Christiaens, Daniel J. Price +9
We present new high-contrast images in near-infrared wavelengths ( = 1.04, 1.24, 1.62, 2.18 and 3.78m) of the young variable star CQ Tau, aiming to constrain the presence of…
Kinematic evidence for an embedded planet in the IM Lupi disc
Harrison J. Verrios, Daniel J. Price, Christophe Pinte +2
We test the hypothesis that an embedded giant planet in the IM Lupi protostellar disc can produce velocity kinks seen in CO line observations as well as the spiral arms seen in sca…
The Dark Energy Survey Supernova Program results: Type Ia Supernova brightness correlates with host galaxy dust
Cole Meldorf, Antonella Palmese, Dillon Brout +68
Cosmological analyses with type Ia supernovae (SNe Ia) often assume a single empirical relation between color and luminosity () and do not account for varying host-galaxy dust p…
Observational window effects on multi-object Reverberation Mapping
Umang Malik, Rob Sharp, Paul Martini +6
Contemporary reverberation mapping campaigns are employing wide-area photometric data and high-multiplex spectroscopy to efficiently monitor hundreds of active galactic nuclei (AGN…
The protoplanetary disc around HD 169142: circumstellar or circumbinary?
P. P. Poblete, N. Cuello, S. Pérez +12
Stellar binaries represent a substantial fraction of stellar systems, especially among young stellar objects. Accordingly, binaries play an important role in setting the architectu…
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…
