Photometric analysis of Magellanic Cloud R Coronae Borealis Stars in the recovery phase of their declines
Robyn M. Woollands, P. L. Cottrell, A. Udalski
This paper presents the initial results of a multi-site photometric programme to examine the extraordinary behaviour displayed by 18 R Coronae Borealis (RCB) stars in the Magellani…
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…
