Oscillations in Procyon A: First results from a multi-site campaign
S. Hekker, T. Arentoft, H. Kjeldsen +45
Procyon A is a bright F5IV star in a binary system. Although the distance, mass and angular diameter of this star are all known with high precision, the exact evolutionary state is…
The Keck Aperture Masking Experiment: Multi-Wavelength Observations of 6 Mira Variables
H. C. Woodruff, P. G. Tuthill, J. D. Monnier +5
The angular diameters of six oxygen rich Mira-type long-period variables have been measured at various near-infrared (NIR) wavelengths using the aperture masking technique in an ex…
A search for solar-like oscillations in K giants in the globular cluster M4
S. Frandsen, H. Bruntt, F. Grundahl +10
To expand the range in the colour-magnitude diagram where asteroseismology can be applied, we organized a photometry campaign to find evidence for solar-like oscillations in giant…
The radius and mass of the subgiant star bet Hyi from interferometry and asteroseismology
J. R. North, J. Davis, T. R. Bedding +7
We have used the Sydney University Stellar Interferometer (SUSI) to measure the angular diameter of beta Hydri. This star is a nearby G2 subgiant whose mean density was recently me…
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…
Radial velocities of five globular clusters obtained with AAOmega
P. Székely, L. L. Kiss, K. Szatmáry +3
Using the recently commissioned multi-object spectrograph AAOmega on the 3.9m AAT we have obtained medium-resolution near-infrared spectra for 10,500 stars in and around five south…
Observations of solar-like oscillations
Timothy R. Bedding, Hans Kjeldsen
There has been tremendous progress in observing oscillations in solar-type stars. In a few short years we have moved from ambiguous detections to firm measurements. We briefly revi…
Multisite campaign on the open cluster M67. III. Delta Scuti pulsations in the blue stragglers
H. Bruntt, D. Stello, J. C. Suarez +20
We have made an asteroseismic analysis of the variable blue stragglers in the open cluster M67. The data set consists of photometric time series from eight sites using nine 0.6-2.1…
A wide-field kinematic survey for tidal tails around five globular clusters
L. L. Kiss, P. Szekely, T. R. Bedding +2
Using the AAOmega instrument of the Anglo-Australian Telescope, we have obtained medium-resolution near-infrared spectra of 10,500 stars in two-degree fields centered on the galact…
Eclipsing binaries in the MACHO database: New periods and classifications for 3031 systems in the Large Magellanic Cloud
A. Derekas, L. L. Kiss, T. R. Bedding
Eclipsing binaries offer a unique opportunity to determine fundamental physical parameters of stars using the constraints on the geometry of the systems. Here we present a reanalys…
Solar-like oscillations in the G2 subgiant beta Hydri from dual-site observations
Timothy R. Bedding, Hans Kjeldsen, Torben Arentoft +16
We have observed oscillations in the nearby G2 subgiant star beta Hyi using high-precision velocity observations obtained over more than a week with the HARPS and UCLES spectrograp…
Asteroseismology from solar-like oscillations
Timothy R. Bedding, Hans Kjeldsen
There has been tremendous progress in observing oscillations in solar-type stars. In a few short years we have moved from ambiguous detections to firm measurements. We briefly revi…
Solar-like oscillations in open cluster stars
D. Stello, H. Bruntt, T. Arentoft +19
Asteroseismology of stellar clusters is potentially a powerful tool. The assumption of a common age, distance, and chemical composition provides constraints on each cluster member,…
Multisite campaign on the open cluster M67. II. Evidence for solar-like oscillations in red giant stars
D. Stello, H. Bruntt, H. Kjeldsen +19
Measuring solar-like oscillations in an ensemble of stars in a cluster, holds promise for testing stellar structure and evolution more stringently than just fitting parameters to s…
