The web-PLOP observation prioritisation system
Colin Snodgrass, Yiannis Tsapras, Rachel Street +4
We present a description of the automated system used by RoboNet to prioritise follow up observations of microlensing events to search for planets. The system keeps an up-to-date r…
Optical observations of 23 distant Jupiter Family Comets, including 36P/Whipple at multiple phase angles
Colin Snodgrass, Stephen C. Lowry, Alan Fitzsimmons
We present photometry on 23 Jupiter Family Comets (JFCs) observed at large heliocentric distance, primarily using the 2.5m Isaac Newton Telescope (INT). Snap-shot images were taken…
Limits on additional planetary companions to OGLE-2005-BLG-390L
D. Kubas, A. Cassan, M. Dominik +1
We investigate constraints on additional planets orbiting the distant M-dwarf star OGLE-2005-BLG-390L, around which photometric microlensing data has revealed the existence of the…
Forms and Rotational States of the Nuclei of Ecliptic Comets
Colin Snodgrass
In this thesis I present measurements of the physical properties of the nuclei of Jupiter Family comets (JFCs), based on time-series observations. From the time-series photometry r…
Photometry of cometary nuclei: Rotation rates, colours and a comparison with Kuiper Belt Objects
Colin Snodgrass, Stephen C. Lowry, Alan Fitzsimmons
We present time-series data on Jupiter Family Comets (JFCs) 17P/Holmes, 47P/Ashbrook-Jackson and 137P/Shoemaker-Levy 2. In addition we also present results from `snap-shot' observa…
Microlens OGLE-2005-BLG-169 Implies Cool Neptune-Like Planets are Common
A. Gould, A. Udalski, D. An +33
We detect a Neptune mass-ratio (q~8e-5) planetary companion to the lens star in the extremely high-magnification (A~800) microlensing event OGLE-2005-BLG-169. If the parent is a ma…
