Whole Earth Telescope Observations of the subdwarf B star KPD 1930+2752: A rich, short period pulsator in a close binary
M. D. Reed, S. L. Harms, S. Poindexter +58
KPD 1930+2752 is a short-period pulsating subdwarf B (sdB) star. It is also an ellipsoidal variable with a known binary period just over two hours. The companion is most likely a w…
Asymmetric Heating of the HR 4796A Dust Ring Due to Pericenter Glow
Margaret Moerchen, Laura Churcher, Charles Telesco +3
We have obtained new resolved images of the well-studied HR 4796A dust ring at 18 and 25 microns with the 8-meter Gemini telescopes. These images confirm the previously observed sp…
The Solar Neighborhood. XXII. Parallax Results from the CTIOPI 0.9m Program: Trigonometric Parallaxes of 64 Nearby Systems with 0\farcs5 1\farcs0 yr (SLOWMO sample)
Adric R. Riedel, John P. Subasavage, Charlie T. Finch +7
We present trigonometric parallaxes of 64 stellar systems with proper motions between 0\farcs5 yr and 1\farcs0 yr from the ongoing RECONS (Research Consortium On Near…
Abundance analysis for long period variables. Velocity effects studied with O-rich dynamic model atmospheres
T. Lebzelter, W. Nowotny, S. Höfner +3
(abbreviated) Measuring the surface abundances of AGB stars is an important tool for studying the effects of nucleosynthesis and mixing in the interior of low- to intermediate mass…
Spitzer and near-infrared observations of a new bi-polar protostellar outflow in the Rosette Molecular Cloud
Jason E. Ybarra, Elizabeth A. Lada, Zoltan Balog +2
We present and discuss \emph{Spitzer} and near-infrared H observations of a new bi-polar protostellar outflow in the Rosette Molecular Cloud. The outflow is seen in all four…
