Mode Instability and a Massive, Isolated Outburst in the Pulsating White Dwarf GD 1212
J. J. Hermes, Keaton J. Bell, Andrew H. Dublin +8
We analyze a large brightening event that lasted for roughly half a day in the pulsating hydrogen-atmosphere white dwarf GD 1212 during K2 Campaign 12 of the extended Kepler missio…
DebrisWatch II: Digging deeper for geosynchronous debris
James A. Blake, Benjamin F. Cooke, Cristina Paragini +27
The geosynchronous (GSO) debris environment is continually evolving. Regular monitoring of the region is consequently of great importance, though the trade-off between coverage and…
Brightness, Colour, Polarisation: A Multi-Instrument Observation Campaign of the Gorizont-6 Satellite
Robert J. S Airey, Paul Chote, Klaas Wiersema +15
We present a coordinated multi-instrument photometric and polarimetric study of the defunct geosynchronous satellite, Gorizont-6. This observation campaign combined wide-field mult…
High-Precision Photometry with a scientific CMOS Camera: II On-Sky Testing of the Marana camera at the NGTS facility
Ioannis Apergis, Daniel Bayliss, Paul Chote +24
Modern scientific CMOS cameras offer very fast readout speeds and low read noise. In this study, we evaluate the performance of the Andor Marana CMOS camera through on-sky testing…
A search for photometric variability towards the globular cluster M3 with the TWenty Inch Survey Telescope
Morgan A. Mitchell, Paul Chote, James McCormac +9
We present the commissioning results and first scientific observations from the newly installed TWIST observatory - a 50 cm telescope equipped with an sCMOS camera providing a $36.…
Lord of the (sub-)Rings : Mapping the surface reflectance and spin-axis of Ajisai
Robert J. S Airey, Paul Chote, James A. Blake +4
Active debris removal techniques are posed to become an important tool in maintaining the safety of the near-Earth space environment. These techniques rely on a clear understanding…
