Pulsations in the atmosphere of the rapidly oscillating Ap star 10 Aquilae
M. Sachkov, O. Kochukhov, T. Ryabchikova +4
The rapidly oscillating Ap (roAp) star 10 Aql shows one of the lowest photometric pulsation amplitudes and is characterized by an unusual spectroscopic pulsational behavior compare…
MOST detects SPBe pulsations in HD 127756 & HD 217543: Asteroseismic rotation rates independent of vsini
C. Cameron, H. Saio, R. Kuschnig +7
The MOST (Microvariability and Oscillations of Stars) satellite has discovered SPBe (Slowly Pulsating Be) oscillations in the stars HD 127756 (B1/B2 Vne) and HD 217543 (B3 Vpe). Fo…
Abundance analysis of seven delta Scuti Stars
L. Fossati, K. Kolenberg, P. Reegen +1
The current knowledge of the abundance pattern in delta Scuti stars is based on the analysis of just a few field stars. We aim to determine the general chemical properties of the a…
A heuristic derivation of the uncertainty of the frequency determination in time series data
T. Kallinger, P. Reegen, W. W. Weiss
Context: Several approaches to estimate frequency, phase and amplitude errors in time series analyses were reported in the literature, but they are either time consuming to compute…
Nonradial p-modes in the G9.5 giant epsilon Oph? Pulsation model fits to MOST photometry
T. Kallinger, D. B. Guenther, J. M. Matthews +6
The G9.5 giant eps Oph shows evidence of radial p-mode pulsations in both radial velocity and luminosity. We re-examine the observed frequencies in the photometry and radial veloci…
Late stages of the evolution of A-type stars on the main sequence: comparison between observed chemical abundances and diffusion models for 8 Am stars of the Praesepe cluster
L. Fossati, S. Bagnulo, R. Monier +5
Aims. We aim to provide observational constraints on diffusion models that predict peculiar chemical abundances in the atmospheres of Am stars. We also intend to check if chemical…
