Overcoming Separation Between Counterparts Due to Unknown Proper Motions in Catalogue Cross-Matching
Tom J. Wilson
To perform precise and accurate photometric catalogue cross-matches -- assigning counterparts between two separate datasets -- we need to describe all possible sources of uncertain…
A Naive Bayes Classifier for identifying Class II YSOs
Andrew J. Wilson, Ben S. Lakeland, Tom J. Wilson +1
A naive Bayes classifier for identifying Class II YSOs has been constructed and applied to a region of the Northern Galactic Plane containing 8 million sources with good quality Ga…
Hydrogen Emission from Accretion and Outflow in T Tauri Stars
Tom J. G. Wilson, S. Matt, T. J. Harries +1
Radiative transfer modelling offers a powerful tool for understanding the enigmatic hydrogen emission lines from T Tauri stars. This work compares optical and near-IR spectroscopy…
Hiding in plain sight: observing planet-starspot crossings with the James Webb Space Telescope
Giovanni Bruno, Nikole K. Lewis, Jeff A. Valenti +9
Transiting exoplanets orbiting active stars frequently occult starspots and faculae on the visible stellar disc. Such occultations are often rejected from spectrophotometric transi…
Discovery of an Edge-on Circumstellar Debris Disk Around BD+45598: a Newly Identifed Member of the Pictoris Moving Group
Sasha Hinkley, Elisabeth C. Matthews, Charlène Lefevre +24
We report the discovery of a circumstellar debris disk viewed nearly edge-on and associated with the young, K1 star BD+45598 using high-contrast imaging at 2.2m obtain…
Disentangling the planet from the star in late type M dwarfs: A case study of TRAPPIST-1g
Hannah R. Wakeford, Nikole K. Lewis, Julia Fowler +10
The atmospheres of late M stars represent a significant challenge in the characterization of any transiting exoplanets due to the presence of strong molecular features in the stell…
A Contaminant-Free Catalogue of Gaia DR2-WISE Galactic Plane Matches: Including the Effects of Crowding in the Cross-Matching of Photometric Catalogues
Tom J Wilson, Tim Naylor
Faint, hidden contaminants in the point-spread functions (PSFs) of stars cause shifts to their measured positions. Wilson & Naylor (2017) showed failing to account for these shifts…
The Complete transmission spectrum of WASP-39b with a precise water constraint
Hannah R. Wakeford, David K. Sing, Drake Deming +12
WASP-39b is a hot Saturn-mass exoplanet with a predicted clear atmosphere based on observations in the optical and infrared. Here we complete the transmission spectrum of the atmos…
Improving Catalogue Matching By Supplementing Astrometry with Additional Photometric Information
Tom J. Wilson, Tim Naylor
The matching of sources between photometric catalogues can lead to cases where objects of differing brightness are incorrectly assumed to be detections of the same source. The reje…
The Effect of Unresolved Contaminant Stars on the Cross-Matching of Photometric Catalogues
Tom J. Wilson, Tim Naylor
A fundamental process in astrophysics is the matching of two photometric catalogues. It is crucial that the correct objects be paired, and that their photometry does not suffer fro…
The JCMT Gould Belt Survey: Evidence for radiative heating and contamination in the W40 complex
D. Rumble, J. Hatchell, K. Pattle +55
We present SCUBA-2 450μm and 850μm observations of the W40 complex in the Serpens-Aquila region as part of the James Clerk Maxwell Telescope (JCMT) Gould Belt Survey (GBS) of nearb…
The age of Taurus - environmental effects on disc lifetimes
Jon M. Rees, T. Wilson, C. P. M. Bell +2
Using semi-empirical isochrones, we find the age of the Taurus star-forming region to be 3-4 Myr. Comparing the disc fraction in Taurus to young massive clusters suggests discs sur…
