Investigating the Nature of Variable Class I and Flat Spectrum Protostars Using 2-4m Spectroscopy
Tracy L. Beck
In this study I present new K and L-band infrared photometry and 2-4m spectra of ten Class I and flat spectrum stars forming within the Taurus dark cloud complex. Nine source…
The Structure of the Inner HH 34 Jet from Optical Integral Field Spectroscopy
Tracy L. Beck, A. Riera, A. C. Raga +1
We present high spatial resolution optical integral field spectroscopy of a collimated Herbig-Haro jet viewed nearly edge-on. Maps of the line emission, velocity centroid, and velo…
Trigonometric Parallaxes of Central Stars of Planetary Nebulae
Hugh C. Harris, Conard C. Dahn, Blaise Canzian +11
Trigonometric parallaxes of 16 nearby planetary nebulae are presented, including reduced errors for seven objects with previous initial results and results for six new objects. The…
Spectropolarimetry of the 3.4 micron absorption feature in NGC 1068
R. E. Mason, G. S. Wright, A. Adamson +1
In order to test the silicate-core/organic-mantle model of galactic interstellar dust, we have performed spectropolarimetry of the 3.4 micron C-H bond stretch that is characteristi…
Physical parameters of two very cool T dwarfs
D. Saumon, M. S. Marley, S. K. Leggett +8
We present new infrared spectra of the T8 brown dwarf 2MASS J04151954-0935066: 2.9-4.1 micron spectra obtained with the Infrared Camera and Spectrograph on the Subaru Telescope, an…
Observational constraints on the evolutionary connection between PG 1159 stars and DO white dwarfs
S. D. Huegelmeyer, S. Dreizler, K. Werner +3
The Sloan Digital Sky Survey has provided spectra of a large number of new PG 1159 stars and DO white dwarfs. This increase in known hot H-deficient compact objects significantly i…
