Super-Nyquist asteroseismology with the Kepler Space Telescope
Simon J. Murphy, Hiromoto Shibahashi, Donald W. Kurtz
Barycentric corrections made to the timing of Kepler observations, necessitated by variations in light arrival time at the satellite, break the regular time-sampling of the data --…
Kepler Fourier concepts: The performance of the Kepler data pipeline
S. J. Murphy
Given the extreme precision attainable with the Kepler Space Telescope, the mitigation of instrumental artefacts is very important. In an earlier paper (Murphy 2012), the character…
A High-Resolution Spectroscopic Search for the Remaining Donor for Tycho's Supernova
Wolfgang E. Kerzendorf, David Yong, Brian P. Schmidt +12
In this paper, we report on our analysis using Hubble Space Telescope astrometry and Keck-I HIRES spectroscopy of the central six stars of Tycho's supernova remnant (SN 1572). With…
Pulsational amplitude growth of the star KIC 3429637 (HD 178875) in the context of Am and rho Puppis stars
Simon J. Murphy, A. Grigahcene, E. Niemczura +2
KIC 3429637 (HD 178875) is a delta Sct star whose light-curve shows continuous pulsational amplitude growth in Kepler Mission photometry. Analysis of the three largest amplitude pe…
The Most Metal-Poor Stars. I. Discovery, Data, and Atmospheric Parameters
John E. Norris, M. S. Bessell, David Yong +7
We report the discovery of 34 stars in the Hamburg/ESO Survey for metal-poor stars and the Sloan Digital Sky Survey that have [Fe/H] < -3.0. Their median and minimum abundances are…
Rapid disappearance of a warm, dusty circumstellar disk
Carl Melis, B. Zuckerman, Joseph H. Rhee +3
Stars form with gaseous and dusty circumstellar envelopes, which rapidly settle into disks that eventually give rise to planetary systems. Understanding the process by which these…
