Element enhancements along the entire AGB phase
E. C. Wylie-de Boer, P. L. Cottrell
The results of a study of the AGB phase of stellar evolution are presented. Abundances have been determined for Fe, C, O, the light s-process elements, Y and Zr, the heavy s-proces…
A new method for the spectroscopic identification of stellar non-radial pulsation modes. II. Mode identification of the Delta Scuti star FG Virginis
W. Zima, D. Wright, J. Bentley +7
We present a mode identification based on new high-resolution time-series spectra of the non-radially pulsating Delta Scuti star FG~Vir (HD 106384, V = 6.57, A5V). From 2002 Februa…
Heavy Element Abundances in Giant Stars of 47 Tuc
E. C. Wylie, P. L. Cottrell, C. A. Sneden +1
This research forms part of an investigation into heavy element abundances in Asymptotic Giant Branch (AGB) stars in various stellar environments. Seven giant stars in the southern…
Dynamical phasing of Type II Cepheids
J. A. McSaveney, K. R. Pollard, P. L. Cottrell
In this paper we examine the problems of phasing using light curves and offer an alternate technique using the changes in acceleration to establish the zero point. We give astrophy…
Asteroseismology of the Beta Cephei star Nu Eridani: photometric observations and pulsational frequency analysis
G. Handler, R. R. Shobbrook, M. Jerzykiewicz +19
We undertook a multisite photometric campaign for the Beta Cephei star Nu Eridani. More than 600 hours of differential photoelectric uvyV photometry were obtained with 11 telescope…
Velocity distribution of stars in the solar neighbourhood
J. Skuljan, J. B. Hearnshaw, P. L. Cottrell
A two-dimensional velocity distribution in the UV-plane has been obtained for stars in the solar neighbourhood, using the Hipparcos astrometry for over 4000 survey stars with paral…
