The rotation and coma profiles of comet C/2004 Q2 (Machholz)
Maarten Reyniers, Pieter Degroote, Dennis Bodewits +2
Aims. Rotation periods of cometary nuclei are scarce, though important when studying the nature and origin of these objects. Our aim is to derive a rotation period for the nucleus…
A Spectroscopic and Photometric Study of the Metal-Poor, Pulsating, Post-AGB Binary HD 46703
Bruce J. Hrivnak, Hans Van Winckel, Maarten Reyniers +3
The metal-poor post-AGB star HD 46703 is shown to be a single-line spectroscopic binary with a period of 600 days, a high velocity of -94 km/s, and an orbital eccentricity of 0.3.…
Kinematics and H_2 morphology of the multipolar Post-AGB star IRAS 16594-4656
G. C. Van de Steene, T. Ueta, P. A. M. van Hoof +2
context: The spectrum of IRAS 16594-4656 shows shock excited H_2 emission and collisionally excited emission lines such as[O I],[C I],and [Fe II]. aim: The goal is to determine the…
