A first-overtone RR Lyrae star with cyclic period changes
A. Derekas, L. L. Kiss, A. Udalski +2
A detailed light curve analysis is presented for a first-overtone RR Lyrae star, MACHO* J050918.712-695015.31, based on MACHO and OGLE-III observations. As a foreground object of t…
Altair: The Brightest Delta Scuti Star
D. L. Buzasi, H. Bruntt, T. R. Bedding +7
We present an analysis of observations of the bright star Altair (alpha Aql) obtained using the star camera on the Wide-Field Infrared Explorer (WIRE) satellite. Although Altair li…
Period and chemical evolution of SC stars
Albert A. Zijlstra, T. R. Bedding, Andrew J. Markwick +8
The SC and CS stars are thermal-pulsing AGB stars with C/O ratio close to unity. Within this small group, the Mira variable BH Cru recently evolved from spectral type SC (showing Z…
Simulating stochastically excited oscillations. The mode lifetime of xi Hya
D. Stello, H. Kjeldsen, T. R. Bedding +5
The discovery of solar-like oscillations in the giant star xy Hya (G7III) was reported by Frandsen et al. (2002). Their frequency analysis was very limited due to alias problems in…
