Revealing Substructure in the Galactic Halo - The SEKBO RR Lyrae Survey
Stefan C. Keller, Simon Murphy, Sayuri Prior +2
We present a search for RR Lyrae variable stars from archival observations of the Southern Edgeworth-Kuiper Belt Object survey. The survey covers 1675 square degrees along the ecli…
Identification and characterization of 15265 super-Nyquist frequencies in 1309 δ Scuti stars from Kepler photometry
Yanqi Mo, Weikai Zong, Xuan Wang +5
The frequency of pressure (p) mode in ~Scuti stars can exceed the Nyquist limit of \textit{Kepler} long-cadence photometry. {These 'super-Nyquist frequencies' (SNFs) are observ…
EuSpRIG 2006 Commercial Spreadsheet Review
Simon Murphy
This management summary provides an outline of a commercial spreadsheet review process. The aim of this process is to ensure remedial or enhancement work can safely be undertaken o…
KIC 4142768: An Evolved Gamma Doradus/Delta Scuti Hybrid Pulsating Eclipsing Binary with Tidally Excited Oscillations
Zhao Guo, Jim Fuller, Avi Shporer +5
We present the characterization of KIC 4142768, an eclipsing binary with two evolved A-type stars in an eccentric orbit with a period of 14 days. We measure the fundamental paramet…
ET White Paper: To Find the First Earth 2.0
Jian Ge, Hui Zhang, Weicheng Zang +163
We propose to develop a wide-field and ultra-high-precision photometric survey mission, temporarily named "Earth 2.0 (ET)". This mission is designed to measure, for the first time,…
Theory and evidence of global Rossby waves in upper main-sequence stars: r-mode oscillations in many Kepler stars
Hideyuki Saio, Donald W. Kurtz, Simon Murphy +2
Asteroseismic inference from pressure modes (p modes) and buoyancy, or gravity, modes (g modes) is ubiquitous for stars across the Hertzsprung--Russell diagram. Until now, however,…
