Aims. We present methodology to derive high-precision estimates of the fundamental parameters of double-lined spectroscopic binaries. We apply the methods to the case study of the double-lined β  Cephei star β  Centauri. We also present a detailed analysis of β  Centauri's line-profile variations caused by its oscillations. Methods. High-resolution spectral time series and visual or interferometric data with a good phase distribution along the orbital period are required. We point out that a… Expand

Investigating potential planetary nebula/cluster pairs
Context. Fundamental parameters characterizing the end-state of intermediate-mass stars may be constrained by discovering planetary nebulae (PNe) in open clusters (OCs). Cluster membership may beExpand
Asteroseismology of beta Cephei and Be type stars
The thesis focuses on the asteroseismology of main sequence B-type stars, particularly \(\beta\) Cephei and Be stars. Photometric observations of these stars were analysed in order to detect stellarExpand
SUSI: an update on instrumental developments and science
The Sydney University Stellar Interferometer is a long baseline optical interferometer located in northern New South Wales, Australia and a software scheduler has been developed to automate much of the observational procedure including the acquisition of a star, fringe search and acquisition, recording of fringe scans, and the taking of photometric scans.
