The 218 day period of the peculiar late B-type star HD 101584
Eric J. Bakker, Henny J. G. L. M. Lamers, L. B. F. M. Waters +1
We have searched for periodicity in the photometric and spectroscopic variations of the enigmatic star HD 101584 and found a long-term variability on a typical time scale of 1700 d…

Detection of C2, CN, and NaID absorption in the AGB remnant of HD56126
Eric J. Bakker, L. B. F. M. Waters, Henny J. G. L. M. Lamers +2
We present the detection of molecular absorption lines in the optical spectrum of the post-AGB star HD56126. The C2 Phillips A^{1}Π_{u}-X^{1}Σ^{+}_{g} (1,0), (2,0), and (3,0); Swan…

The velocity gradient in the pseudo-photosphere of the peculiar supergiant HD101584
Eric J. Bakker
In this paper preliminary results are presented based on a study of the low and high resolution ultraviolet spectrum of the peculiar supergiant (post-AGB star) HD101584. By a compa…
