A Tight Upper Limit on Oscillations in the Ap star Epsilon Ursae Majoris from WIRE Photometry
Alon Retter, Timothy R. Bedding, Derek L. Buzasi +2
Observations of Epsilon UMa obtained with the star tracker on the Wide Field Infrared Explorer (WIRE) satellite during a month in mid-2000 are analyzed. This is one of the most pre…
Red variables in the OGLE-II database. II. Comparison of the Large and Small Magellanic Clouds
L. L. Kiss, T. Bedding
We present period-luminosity relations for more than 3,200 red variable stars in the Small Magellanic Cloud observed in the second phase of the Optical Gravitational Lensing Experi…
Ultra-high-precision velocity measurements of oscillations in alpha Cen A
R. Paul Butler, Timothy R. Bedding, Hans Kjeldsen +5
We have made differential radial velocity measurements of the star alpha Cen A using two spectrographs, UVES and UCLES, both with iodine absorption cells for wavelength referencing…
The first CCD photometric study of the open cluster NGC 2126
A. Gaspar, L. L. Kiss, T. R. Bedding +6
We present the first CCD photometric observations of the northern open cluster NGC 2126. Data were taken on eight nights in February and December 2002 with a total time span of ~57…
Erratum: "Oscillations in Arcturus from WIRE photometry" (ApJ, 591, L151 [2003])
Alon Retter, Timothy R. Bedding, Derek L. Buzasi +2
The value of the mode lifetime given in the first paragraph of the Discussion should be divided by 2pi and is therefore 2.0 days rather than 13 days.
Red variables in the OGLE-II database. I. Pulsations and period-luminosity relations below the tip of the Red Giant Branch of the LMC
L. L. Kiss, T. Bedding
We present period-luminosity relations for more than 23,000 red giants in the Large Magellanic Cloud observed by the OGLE-II microlensing project. The OGLE period values were combi…
Colour ratios of pulsation amplitudes in red giants
J. P. Huber, T. R. Bedding, S. J. O'Toole
We have analysed the three-colour photometry of 34 pulsating red giants that was published by Percy, Wilson and Henry (2001). As is common with semiregulars, many of these stars ha…
Oscillations in Arcturus from WIRE photometry
A. Retter, T. Bedding, D. L. Buzasi +2
Observations of the red giant Arcturus (Alpha Boo) obtained with the star tracker on the Wide Field Infrared Explorer (WIRE) satellite during a baseline of 19 successive days in 20…
Confirmation of solar-like oscillations in eta Bootis
H. Kjeldsen, T. R. Bedding, I. K. Baldry +10
We obtained time-series spectroscopy of the G0 subgiant eta Boo in an attempt to confirm the solar-like oscillations reported by Kjeldsen et al. (1995). We recorded 1843 spectra ov…
Solar-like Oscillations (Invited Review)
Timothy R. Bedding, Hans Kjeldsen
The five-minute oscillations in the Sun have provided a wealth of information about the solar interior. After many attempts, positive detections of similar oscillations in solar-ty…
The mass of the neutron star in Vela X-1 and tidally induced non-radial oscillations in GP Vel
H. Quaintrell, A. J. Norton, T. D. C. Ash +5
We report new radial velocity observations of GP Vel/HD77581, the optical companion to the eclipsing X-ray pulsar Vela X-1. Using data spanning more than two complete orbits of the…
