Quantum computation of molecular geometry via many-body nuclear spin echoes
C. Zhang, R. G. Cortiñas, A. H. Karamlou +320
Quantum-information-inspired experiments in nuclear magnetic resonance spectroscopy may yield a pathway towards determining molecular structure and properties that are otherwise ch…
A 16-Year Photometric Campaign on the Eclipsing Novalike Variable DW Ursae Majoris
D. R. S. Boyd, E. de Miguel, J. Patterson +29
We present an analysis of photometric observations of the eclipsing novalike variable DW UMa made by the CBA consortium between 1999 and 2015. Analysis of 372 new and 260 previousl…
A search for previously unrecognised metal-poor subdwarfs in the Hipparcos astrometric catalogue
I. Neill Reid, F. van Wyk, F. Marang +3
We have identified 317 stars included in the Hipparcos astrometric catalogue which have parallaxes measured to a precision of better than 15%, and whose location in the (M_V, (B-V)…
Rapid Oscillations in Cataclysmic Variables. XVII. 1RXS J070407+262501
J. Patterson, J. R. Thorstensen, H. A. Sheets +10
We present a study of the recently discovered intermediate polar 1RXS J070407+262501, distinctive for its large-amplitude pulsed signal at P = 480 s. Radial velocities indicate an…
Time-series Spectroscopy of Pulsating sdB Stars: PG1605+072
S. J. O'Toole, T. R. Bedding, H. Kjeldsen +6
We report the detection of velocity variations in the pulsating sdB star, PG 1605+072. Oscillations are detected at the same frequencies found from photometry and have amplitudes o…
Accretion-disc precession in UX Ursae Majoris
E. de Miguel, J. Patterson, D. Cejudo +25
We report the results of a long campaign of time-series photometry on the nova-like variable UX Ursae Majoris during 2015. It spanned 150 nights, with ~1800 hours of coverage on 12…
Orbital, Superhump, and Superorbital Periods in the Cataclysmic Variables AQ Mensae and IM Eridani
E. Armstrong, J. Patterson, E. Michelsen +6
We report photometric detections of orbital and superorbital signals, and negative orbital sidebands, in the light curves of the nova-like cataclysmic variables AQ Mensae and IM Er…
