An unusually large gaseous transit in a debris disc
Daniela P. Iglesias, Johan Olofsson, Amelia Bayo +9
We present the detection of an unusually large transient gas absorption in several ionized species in the debris disc star HD 37306 using high-resolution optical spectra. We have b…
Searching for a cometary belt around Trappist-1 with ALMA
S. Marino, M. C. Wyatt, G. M. Kennedy +4
Low mass stars might offer today the best opportunities to detect and characterise planetary systems, especially those harbouring close-in low mass temperate planets. Among those s…
A statistically significant lack of debris discs in medium separation binary systems
Ben Yelverton, Grant M. Kennedy, Kate Y. L. Su +1
We compile a sample of 341 binary and multiple star systems with the aim of searching for and characterising Kuiper belt-like debris discs. The sample is assembled by combining sev…
A Gap in the Mass Distribution for Warm Neptune and Terrestrial Planets
David J. Armstrong, Farzana Meru, Daniel Bayliss +2
Structure in the planet distribution provides an insight into the processes that shape the formation and evolution of planets. The Kepler mission has led to an abundance of statist…
The REASONS Survey: Resolved Millimeter Observations of a Large Debris Disk Around the Nearby F Star HD 170773
Aldo G. Sepulveda, Luca Matra, Grant M. Kennedy +15
Debris disks are extrasolar analogs to our own Kuiper Belt and they are detected around at least 17% of nearby Sun-like stars. The morphology and dynamics of a disk encode informat…
ISPY -- NaCo Imaging Survey for Planets around Young stars. Discovery of an M dwarf in the gap between HD 193571 and its debris ring
Arianna Musso Barcucci, Ralf Launhardt, Grant M. Kennedy +19
Context. The interaction between low-mass companions and the debris discs they reside in is still not fully understood. A debris disc can evolve due to self-stirring, a process in…
Exocometary Science
Luca Matrà, Quentin Kral, Kate Su +20
Evidence for exocomets, icy bodies in extrasolar planetary systems, has rapidly increased over the past decade. Volatiles are detected through the gas that exocomets release as the…
Probing Unseen Planet Populations with Resolved Debris Disk Structures
Kate Su, Nick Ballering, Steve Ertel +10
Thousands of exoplanets have been found with many widely different from the ones in our own system. Despite the success, systems with planets in wide orbits analogous to those of J…
Transiting exocomets detected in broadband light by TESS in the Pictoris system
Sebastian Zieba, Konstanze Zwintz, Matthew A. Kenworthy +1
We search for signs of falling evaporating bodies (FEBs, also known as exocomets) in photometric time series obtained for Pictoris after fitting and removing its Scuti type…
ISPY - the NaCo Imaging Survey for Planets around Young stars: A young companion candidate embedded in the R CrA cloud
G. Cugno, S. P. Quanz, R. Launhardt +13
Within the NaCo-ISPY exoplanet imaging program, we aim at detecting and characterizing the population of low-mass companions at wide separations (10AU), focusing in partic…
The PDS 110 observing campaign - photometric and spectroscopic observations reveal eclipses are aperiodic
Hugh P. Osborn, Matthew Kenworthy, Joseph E. Rodriguez +71
PDS 110 is a young disk-hosting star in the Orion OB1A association. Two dimming events of similar depth and duration were seen in 2008 (WASP) and 2011 (KELT), consistent with an ob…
A circumbinary protoplanetary disc in a polar configuration
Grant M. Kennedy, Luca Matrà, Stefano Facchini +6
Nearly all young stars are initially surrounded by `protoplanetary' discs of gas and dust, and in the case of single stars at least 30\% of these discs go on to form planets. The p…
