Possible duality violations in tau decay and their impact on the determination of alpha_s
Oscar Cata, Maarten Golterman, Santiago Peris
We discuss the issue of duality violations in hadronic tau decay. After introducing a physically motivated ansatz for duality violations, we estimate their possible size by fitting…
HATNet Field G205: Follow-Up Observations of 28 Transiting-Planet candidates and Confirmation of the Planet HAT-P-8b
David W. Latham, Gáspár Á. Bakos, Guillermo Torres +16
We report the identification of 32 transiting-planet candidates in HATNet field G205. We describe the procedures that we have used to follow up these candidates with spectroscopic…
Ten New and Updated Multi-planet Systems, and a Survey of Exoplanetary Systems
J. T. Wright, S. Upadhyay, G. W. Marcy +3
We present the latest velocities for 10 multi-planet systems, including a re-analysis of archival Keck and Lick data, resulting in improved velocities that supersede our previously…
A spectroscopic survey of dwarf galaxies in the Coma Cluster: Stellar populations, environment and downsizing
Russell J. Smith, John R. Lucey, Michael J. Hudson +5
We investigate the stellar populations in a sample of 89 faint (M*+2 to M*+4) red galaxies in the Coma cluster, using high S/N spectroscopy from the MMT. Our sample is drawn from t…
The Transit Light Curve Project. X. A Christmas Transit of HD 17156b
Joshua N. Winn, Matthew J. Holman, Gregory W. Henry +6
Photometry is presented of the Dec. 25, 2007 transit of HD 17156b, which has the longest orbital period and highest orbital eccentricity of all the known transiting exoplanets. New…
Selection Functions in Doppler Planet Searches
S. J. O'Toole, C. G. Tinney, H. R. A. Jones +4
We present a preliminary analysis of the sensitivity of Anglo-Australian Planet Search data to the orbital parameters of extrasolar planets. To do so, we have developed new tools f…
