No Period Change in Two Long-Period AM CVn Binaries
Matthew J. Green, Thomas R. Marsh, Jan van Roestel +25
Ultracompact binary systems, consisting of two compact objects in an orbit , should exhibit measurable rates of orbital period change () due t…
Long-term photometric monitoring and spectroscopy of the white dwarf pulsar AR Scorpii
Ingrid Pelisoli, T. R. Marsh, S. G. Parsons +14
AR Scorpii (AR Sco) is the only radio-pulsing white dwarf known to date. It shows a broad-band spectrum extending from radio to X-rays whose luminosity cannot be explained by therm…
A Large Ground-Based Observing Campaign of the Disintegrating Planet K2-22b
Knicole D. Colón, George Zhou, Avi Shporer +27
We present 45 ground-based photometric observations of the K2-22 system collected between December 2016 and May 2017, which we use to investigate the evolution of the transit of th…
High-Speed Photometry of Gaia14aae: An Eclipsing AM CVn That Challenges Formation Models
M. J. Green, T. R. Marsh, D. T. H. Steeghs +19
AM CVn-type systems are ultra-compact, hydrogen-deficient accreting binaries with degenerate or semi-degenerate donors. The evolutionary history of these systems can be explored by…
Hunting For Eclipses: High Speed Observations of Cataclysmic Variables
Liam K Hardy, Martin J McAllister, Vik S Dhillon +12
We present new time-resolved photometry of 74 cataclysmic variables (CVs), 47 of which are eclipsing. 13 of these eclipsing systems are newly discovered. For all 47 eclipsing syste…
