The Pan-STARRS1 Surveys
Pan-STARRS1 has carried out a set of distinct synoptic imaging sky surveys including the $3\pi$ Steradian Survey and the Medium Deep Survey in 5 bands ($grizy_{P1}$). The mean 5$\sigma$ point sourceExpand
The WASP project and the superWASP cameras
ABSTRACT The SuperWASP cameras are wide‐field imaging systems at the Observatorio del Roque de los Muchachos on the island of La Palma in the Canary Islands, and at the Sutherland Station of theExpand
WASP-1b and WASP-2b: Two new transiting exoplanets detected with SuperWASP and SOPHIE
Using the newly commissioned radial-velocity spectrograph SOPHIE at the Observatoire de Haute-Provence, it is found that WasP-1b and WASP-2b exhibit reflex orbital radial-VELocity variations with amplitudes characteristic of planetary-mass companions and in-phase with the photometric orbits. Expand
Photometry of cometary nuclei: Rotation rates, colours and a comparison with Kuiper Belt Objects
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’ observations of cometsExpand
Thermal properties, sizes, and size distribution of Jupiter-family cometary nuclei
We present results from SEPPCoN, an on-going Survey of the Ensemble Physical Properties of Cometary Nuclei. In this report we discuss mid-infrared measurements of the thermal emission from 89 nucleiExpand
The size distribution of Jupiter Family comet nuclei
We present an updated cumulative size distribution (CSD) for Jupiter Family comet (JFC) nuclei, including a rigorous assessment of the uncertainty on the slope of the CSD. The CSD is expressed as aExpand
CCD photometry of distant comets II
R band CCD photometric observations of short period Jupiter family comets in the heliocentric region of 2.11 AU Rh 5:63 AU were performed using the 4.2 m William Herschel Telescope on La Palma inExpand
The impact and recovery of asteroid 2008 TC3
A dedicated search along the approach trajectory recovered 47 meteorites, fragments of a single body named Almahata Sitta, with a total mass of 3.95 kg, identifying the asteroid as F class, now firmly linked to dark carbon-rich anomalous ureilites, a material so fragile it was not previously represented in meteorite collections. Expand
A collision in 2009 as the origin of the debris trail of asteroid P/2010 A2
It is determined that this was an asteroid collision that occurred around 10 February 2009 and can be explained by an initial impact ejecting large clumps of debris that disintegrated and dispersed almost immediately. Expand
CCD photometry of distant comets. III - Ensemble properties of Jupiter-family comets
We describe the results of a ground-based observational “snapshot” study of Jupiter-family comets in the heliocentric range $2.29 \textnormal{ AU} \leq {R}_{\rm h} \leq 5.72 \textnormal{ AU}$.Expand
