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…
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…
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 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…
