Infrared [Fe II] emission from P Cygni's nebula: Atomic data, mass, kinematics, and the 1600 A.D. outburst
Nathan Smith, Patrick Hartigan
We present moderate and high-dispersion 1-2.5 micron spectra of the 10 arcsec nebula around P Cygni, dominated by bright emission lines of [Fe II]. Observed [Fe II] line ratios dis…
Measuring the Magnetic Field on the Classical T Tauri Star TW Hydrae
H. Yang, C. M. Johns-Krull, J. A. Valenti
We present infrared (IR) and optical echelle spectra of the Classical T Tauri star TW Hydrae. Using the optical data, we perform detailed spectrum synthesis to fit atomic and molec…
Proper Motions of the HH 47 Jet Observed with the Hubble Space Telescope
P. Hartigan, S. Heathcote, J. Morse +2
We present a proper motion study of the shock waves within the classic stellar jet HH 47 based on Hubble Space Telescope H-alpha and [S II] images of the region taken over two epoc…
2-D and 3-D Radiation Transfer Models of High-Mass Star Formation
Barbara A. Whitney, Thomas P. Robitaille, Remy Indebetouw +3
2-D and 3-D radiation transfer models of forming stars generally produce bluer 1-10 micron colors than 1-D models of the same evolutionary state and envelope mass. Therefore, 1-D m…
Multiwavelength Observations of 3C 66A during the WEBT campaign of 2003 - 2004
M. Boettcher, J. Harvey, M. Joshi
The BL Lac object 3C 66A was the target of an extensive multiwavelength monitoring campaign from July 2003 through April 2004, involving observations throughout the electromagnetic…
Diffusive Acceleration of Ions at Interplanetary Shocks
Matthew G. Baring, Errol J. Summerlin
Heliospheric shocks are excellent systems for testing theories of particle acceleration in their environs. These generally fall into two classes: (1) interplanetary shocks that are…
Convective Dynamos and the Minimum X-ray Flux in Main Sequence Stars
D. J. Bercik, G. H. FIsher, C. M. Johns-Krull +1
The objective of this paper is to investigate whether a convective dynamo can account quantitatively for the observed lower limit of X-ray surface flux in solar-type main sequence…
Modeling Accelerated Pick-up Ion Distributions at an Interplanetary Shock
Errol J. Summerlin, Matthew G. Baring
The acceleration of interstellar pick-up ions as well as solar wind species has been observed at a multitude of interplanetary (IP) shocks by different spacecraft. The efficiency o…
Spin-Dependent Cyclotron Decay Rates in Strong Magnetic Fields
Matthew G. Baring, Peter L. Gonthier, Alice K. Harding
Cyclotron decay and absorption rates have been well studied in the literature, focusing primarily on spectral, angular and polarization dependence. Astrophysical applications usual…
The loopy UV line profiles of RU Lupi: accretion, outflows, and fluorescence
G. J. Herczeg, F. M. Walter, J. L. Linsky +6
We present far-ultraviolet spectra of the classical T Tauri star RU Lupi covering the 912-1710 A spectral range, as observed by the HST/STIS and FUSE satellites. We use these spect…
Color--Magnitude Diagrams and Luminosity Functions down to the Hydrogen Burning Limit. III. A Preliminary HST Study of NGC6791
I. R. King, L. R. Bedin, G. Piotto +3
Using HST ACS/WFC images, we derive the color--magnitude diagram of the old, metal-rich open cluster NGC 6791 to nearly 29th magnitude in V, which is the neighborhood of the hydrog…
Star-Cluster Astrometry with Ground-Based Wide Field Imagers
L. R. Bedin, J. Anderson, G. Piotto +2
We show the astrometric potential of the Wide Field Imager at the focus of the MPI-ESO 2.2m Telescope. Currently, we are able to measure the position of a well-exposed star with a…
SCUBA sub-millimeter observations of gamma-ray bursters IV. GRB 021004, 021211, 030115, 030226, 041006
I. A. Smith, R. P. J. Tilanus, N. Tanvir +7
We discuss our ongoing program of Target of Opportunity (ToO) sub-millimeter observations of gamma-ray bursts (GRBs) using the Sub-millimetre Common-User Bolometer Array (SCUBA) on…
SCUBA sub-millimeter observations of gamma-ray bursters III. GRB 030329: The brightest sub-millimeter afterglow to date
I. A. Smith, R. P. J. Tilanus, N. Tanvir +4
We discuss our ongoing program of Target of Opportunity (ToO) sub-millimeter observations of gamma-ray bursts (GRBs) using the Sub-millimetre Common-User Bolometer Array (SCUBA) on…
Potential Vorticity Evolution of a Protoplanetary Disk with An Embedded Protoplanet
H. Li, S. Li, J. Koller +5
We present two-dimensional inviscid hydrodynamic simulations of a protoplanetary disk with an embedded planet, emphasizing the evolution of potential vorticity (the ratio of vortic…
The white dwarf cooling sequence in NGC 6791
L. R. Bedin, M. Salaris, G. Piotto +5
In the old, populous, and metal-rich open cluster NGC 6791 we have used deep HST/ACS images to track the white dwarf cooling sequence down to m_F606W~28.5. The white dwarf luminosi…
Multiwavelength Spectral Models for SNR G347.3-0.5 from Non-Linear Shock Acceleration
Matthew G. Baring, Donald C. Ellison, Patrick O. Slane
The remnant G347.3-0.5 exhibits strong shell emission in the radio and X-ray bands, and has a purported detection in the TeV gamma-ray band by the CANGAROO-II telescope. The CANGAR…
