Five Planets Orbiting 55 Cancri
Debra A. Fischer, Geoffrey W. Marcy, R. Paul Butler +9
We report 18 years of Doppler shift measurements of a nearby star, 55 Cancri, that exhibit strong evidence for five orbiting planets. The four previously reported planets are stron…
Solar-like oscillations in the metal-poor subgiant nu Indi: II. Acoustic spectrum and mode lifetime
F. Carrier, H. Kjeldsen, T. R. Bedding +7
Convection in stars excites resonant acoustic waves which depend on the sound speed inside the star, which in turn depends on properties of the stellar interior. Therefore, asteros…
The Search for an Atmospheric Signature of the Transiting Exoplanet HD 149026b
Nassim Bozorgnia, Jonathan J. Fortney, Chris McCarthy +2
HD 149026b is a short-period, Saturn-mass planet that transits a metal-rich star. The planet's radius, determined by photometry, is remarkably small compared to other known transit…
An Activity Catalogue of Southern Stars
J. S. Jenkins, H. R. A. Jones, C. G. Tinney +6
We have acquired high-resolution echelle spectra of 225 F6-M5 type stars in the southern hemisphere. The stars are targets or candidates to be targets for the Anglo-Australian Plan…
