Measuring turbulent motion in planet-forming disks with ALMA: A detection around DM Tau and non-detections around MWC 480 and V4046 Sgr
Kevin Flaherty, A. Meredith Hughes, Jacob B. Simon +6
Turbulence is a crucial factor in many models of planet formation, but it has only been directly constrained among a small number of planet forming disks. Building on the upper lim…
Modelling the Spatial Distribution and Origin of CO Gas in Debris Disks
Antonio Hales, Uma Gorti, John Carpenter +2
The detection of gas in debris disks raises the question of whether this gas is a remnant from the primordial protoplanetary phase, or released by the collision of secondary bodies…
The Inner Disk and Accretion Flow of the Close Binary DQ Tau
James Muzerolle, Kevin Flaherty, Zoltan Balog +2
We present multi-epoch optical and near-infrared (NIR) photometry and spectroscopy of the spectroscopic binary T Tauri star DQ Tau. The photometric monitoring, obtained using SMART…
On the Production of He, C and N by Low and Intermediate Mass Stars: A Comparison of Observed and Model-Predicted Planetary Nebula Abundances
R. B. C. Henry, B. G. Stephenson, M. M. Miller Bertolami +2
The primary goal of this paper is to make a direct comparison between the measured and model-predicted abundances of He, C and N in a sample of 35 well-observed Galactic planetary…
Co-spatial Long-slit UV/Optical Spectra of Ten Galactic Planetary Nebulae with HST/STIS I. Description of the Observations, Global Emission-line Measurements, and CNO Abundances
Reginald J. Dufour, Karen B. Kwitter, Richard A. Shaw +3
We present observations and initial analysis from an HST/STIS program to obtain the first co-spatial, UV-optical spectra of ten Galactic planetary nebulae (PNe). Our primary object…
Structure and Dynamics of the 13/14 November 2012 Eclipse White-Light Corona
Jay M. Pasachoff, Vojtech Rusin, Metod Saniga +9
Continuing our series of observations of the motion and dynamics of the solar corona over the solar-activity cycle, we observed the corona from sites in Queensland, Australia, duri…
