Spectroscopic Study of IRAS 19285+0517(PDS 100): A Rapidly Rotating Li-Rich K Giant
Bacham E. Reddy, David L. Lambert, Bruce J. Hrivnak +1
We report on photometry and high-resolution spectroscopy for IRAS 19285+0517. The spectral energy distribution based on visible and near-IR photometry and far-IR fluxes shows that…
The Impact of the Massive Young Star GL 2591 on its Circumstellar Material: Temperature, Density and Velocity Structure
Floris F. S. van der Tak, Ewine F. van Dishoeck, Neal J. Evans +2
The temperature, density and kinematics of the gas and dust surrounding the luminous young stellar object GL~2591 are investigated on scales as small as 100 AU, probed by 4.7 micro…
The circumstellar shell of the post-AGB star HD 56126: the 12C12C/12C13C isotope ratio and 12C16O column density
Eric J. Bakker, David L. Lambert
We have made the first detection of circumstellar absorption lines of the 12C13C (Phillips) system 1-0 band and the 12C16O first-overtone 2-0 band in the spectrum of the post-AGB s…
Photospheric composition of the carbon-rich 21 micron post-AGB stars IRAS 22223+4327 and IRAS 04296+3429
Leen Decin, Hans Van Winckel, Christoffel Waelkens +1
We present a detailed chemical analysis on the basis of high-resolution, high signal-to-noise optical spectra of two post-AGB objects IRAS 22223+4327 and IRAS 04296+3429. Both disp…
Further evidence for the planet around 51 Pegasi
Artie P. Hatzes, William D. Cochran, Eric J. Bakker
The discovery of the planet around the solar-type star 51 Pegasi marked a watershed in the search for extrasolar planets. Since then seven other solar-type stars have been discover…
The circumstellar shell of the post-AGB star HD 56126: the CN/CN isotope ratio and fractionation
Eric J. Bakker, David L. Lambert
We have detected circumstellar absorption lines of the CN and CN Violet and Red System in the spectrum of the post-AGB star HD~56126. From a synthetic spectrum analys…
