Planet formation in intermediate-separation binary systems
O. Panić, T. J. Haworth, M. G. Petr-Gotzens +13
We report the first characterisation of the individual discs in the intermediate separation binary systems KK Oph and HD 144668 at millimetre wavelengths. In both systems the circu…
Rapid CO gas dispersal from NO Lup's class III circumstellar disc
J. B. Lovell, G. M. Kennedy, S. Marino +9
We observed the K7 class III star NO Lup in an ALMA survey of the 1-3 Myr Lupus association and detected circumstellar dust and CO gas. Here we show that the J = 3-2 CO emission is…
Hiding Signatures of Gravitational Instability in Protoplanetary Discs with Planets
Sahl Rowther, Farzana Meru, Grant M. Kennedy +2
We carry out three dimensional SPH simulations to show that a migrating giant planet strongly suppresses the spiral structure in self-gravitating discs. We present mock ALMA contin…
Mutual inclinations between giant planets and their debris discs in HD 113337 and HD 38529
Jerry W. Xuan, Grant M. Kennedy, Mark C. Wyatt +1
HD 113337 and HD 38529 host pairs of giant planets, a debris disc, and wide M-type stellar companions. We measure the disc orientation with resolved images from Herschel and constr…
Spin-orbit alignment of the Pictoris planetary system
Stefan Kraus, Jean-Baptiste LeBouquin, Alexander Kreplin +6
A crucial diagnostic that can tell us about processes involved in the formation and dynamical evolutionof planetary systems is the angle between the rotation axis of a star and a p…
A low-mass stellar companion to the young variable star RZ Psc
Grant M. Kennedy, Christian Ginski, Matthew A. Kenworthy +10
RZ Psc is a young Sun-like star with a bright and warm infrared excess that is occasionally dimmed significantly by circumstellar dust structures. Optical depth arguments suggest t…
The unexpected narrowness of eccentric debris rings: a sign of eccentricity during the protoplanetary disc phase
Grant M. Kennedy
This paper shows that the eccentric debris rings seen around the stars Fomalhaut and HD 202628 are narrower than expected in the standard eccentric planet perturbation scenario (so…
No significant correlation between radial velocity planet presence and debris disc properties
Ben Yelverton, Grant M. Kennedy, Kate Y. L. Su
We investigate whether the tentative correlation between planets and debris discs which has been previously identified can be confirmed at high significance. We compile a sample of…
Survey of planetesimal belts with ALMA: gas detected around the Sun-like star HD 129590
Quentin Kral, Luca Matra, Grant Kennedy +2
Gas detection around main sequence stars is becoming more common with around 20 systems showing the presence of CO. However, more detections are needed, especially around later spe…
Herschel Observations of Disks around Late-type Stars
Angelle Tanner, Peter Plavchan, Geoff Bryden +9
A set of twenty late-type (K5-M5) stars were observed with the Herschel Space Observatory at 100 and 160 microns with the goal of searching for far-infrared excesses indicative of…
The HOSTS survey for exozodiacal dust: Observational results from the complete survey
Steve Ertel, Denis Defrère, Philip M. Hinz +43
The Large Binocular Telescope Interferometer (LBTI) enables nulling interferometric observations across the N band (8 to 13 um) to suppress a star's bright light and probe for fain…
ISPY -- NACO Imaging Survey for Planets around Young stars: Survey description and results from the first 2.5 years of observations
R. Launhardt, Th. Henning, A. Quirrenbach +21
The occurrence rate of long-period giant planets around young stars is highly uncertain since it is not only governed by the protoplanetary disc structure and planet formation proc…
The Habitable Exoplanet Observatory (HabEx) Mission Concept Study Final Report
B. Scott Gaudi, Sara Seager, Bertrand Mennesson +183
The Habitable Exoplanet Observatory, or HabEx, has been designed to be the Great Observatory of the 2030s. For the first time in human history, technologies have matured sufficient…
Constraining planet formation around 6-8 stars
Dimitri Veras, Pier-Emmanuel Tremblay, J. J. Hermes +4
Identifying planets around O-type and B-type stars is inherently difficult; the most massive known planet host has a mass of only about . However, planetary systems whi…
