A search for rapid pulsations in the magnetic cool chemically peculiar star HD3980
V. G. Elkin, D. W. Kurtz, L. M. Freyhammer +2
The Ap star HD3980 appears to be a promising roAp candidate based on its fundamental parameters, leading us to search for rapid pulsations with the VLT UV-Visual Echelle Spectrogra…
On the spectroscopic nature of the cool evolved Am star HD151878
L. M. Freyhammer, V. G. Elkin, D. W. Kurtz
Recently, Tiwari, Chaubey, & Pandey (2007) detected the bright component of the visual binary HD151878 to exhibit rapid photometric oscillations through a Johnson B filter with a p…
Discovery of 17 new sharp-lined Ap stars with magnetically resolved lines
L. M. Freyhammer, V. G. Elkin, D. W. Kurtz +2
Chemically peculiar A stars (Ap) are extreme examples of the interaction of atomic element diffusion processes with magnetic fields in stellar atmospheres. The rapidly oscillating…
The fundamental parameters of the roAp star alpha Circini
H. Bruntt, J. R. North, M. Cunha +12
We have used the Sydney University Stellar Interferometer (SUSI) to measure the angular diameter of alpha Cir. This is the first detailed interferometric study of a rapidly oscilla…
A search for rapid pulsations among 9 luminous Ap stars
L. M. Freyhammer, D. W. Kurtz, M. S. Cunha +3
The rapidly oscillating Ap stars are of importance for studying the atmospheric structure of stars where the process of chemical element diffusion is significant. We have performed…
Structure of the hot object in the symbiotic prototype Z And during its 2000-03 active phase
A. Skopal, A. Vittone, L. Errico +4
Aims: To investigate structure of the hot object in the symbiotic prototype Z And during its major 2000-03 active phase. Methods: Analysis of the far ultraviolet, optical low- and…
