Discovery of a Wolf-Rayet Star Through Detection of its Photometric Variability
Colin Littlefield, Peter Garnavich, G. H. Howie Marion +4
We report the serendipitous discovery of a heavily reddened Wolf-Rayet star that we name WR142b. While photometrically monitoring a cataclysmic variable, we detected weak variabili…
Ro-vibrational CO Detected in the ~Pictoris Circumstellar Disk
Matthew R. Troutman, Kenneth H. Hinkle, Joan R. Najita +2
We present high resolution near-infrared spectra of Pictoris - a nearby young star with a debris disk. Fundamental low-J CO absorption lines are detected and strict upper limit…
Near Infrared Spectroscopic Study of V1647 Ori
S. D. Brittain, T. W. Rettig, T. Simon +2
We present new high-resolution infrared echelle spectra of V1647 Ori, the young star that illuminates McNeil's nebula. From the start, V1647 Ori has been an enigmatic source that h…
Dust Settling in Magnetorotationally-Driven Turbulent Discs II: The Pervasiveness of the Streaming Instability and its Consequences
D. A. Tilley, D. S. Balsara, S. D. Brittain +1
We present a series of simulations of turbulent stratified protostellar discs with the goal of characterizing the settling of dust throughout a minimum-mass solar nebula. We compar…
Dust Settling in Magnetorotationally-Driven Turbulent Discs I: Numerical Methods and Evidence for a Vigorous Streaming Instability
Dinshaw S. Balsara, David A. Tilley, Terrence Rettig +1
(Abridged) In this paper we have used the RIEMANN code for computational astrophysics to study the interaction of a realistic distribution of dust grains with gas in a vertically s…
Post-Outburst Observations of V1647 Ori: Detection of a Brief Warm, Molecular Outflow
Sean Brittain, Terrence Rettig, Theodore Simon +4
We present new observations of the fundamental ro-vibrational CO spectrum of V1647 Ori, the young star whose recent outburst illuminated McNeil's Nebula. Previous spectra, acquired…
