Hubble Space Telescope Wide Field Planetary Camera 2 Observations of η Carinae
Hubble Space Telescope (HST) continuum and emission-line images of η Carinae obtained with the Planetary Camera (PC) of the Wide Field Planetary Camera 2 show a startling wealth of detailed structure…
A Divergence-free Upwind Code for Multidimensional Magnetohydrodynamic Flows
- D. Ryu, F. Miniati, T. Jones, A. Frank
- Physics
- 22 July 1998
A description is given for preserving 𝛁 ∙ = 0 in a magnetohydrodynamic (MHD) code that employs the upwind, total variation diminishing (TVD) scheme and Strang type operator splitting for…
A Spitzer Space Telescope Infrared Spectrograph Spectral Atlas of Luminous 8 μm Sources in the Large Magellanic Cloud
- C. Buchanan, J. Kastner, C. Barnbaum
- Physics
- 27 September 2006
We present an atlas of Spitzer Space Telescope Infrared Spectrograph (IRS) spectra of highly luminous, compact, mid-IR sources in the Large Magellanic Cloud. Sources were selected on the basis of IR…
EXPLOSIVE OUTFLOWS POWERED BY THE DECAY OF NON-HIERARCHICAL MULTIPLE SYSTEMS OF MASSIVE STARS: ORION BN/KL
- J. Bally, N. Cunningham, Å. Nordlund
- Physics, Geology
- 23 November 2010
The explosive Becklin–Neugebauer (BN)/Kleinman–Low (KL) outflow emerging from OMC1 behind the Orion Nebula may have been powered by the dynamical decay of a non-hierarchical multiple system ∼500…
THE CHANDRA X-RAY SURVEY OF PLANETARY NEBULAE (ChanPlaNS): PROBING BINARITY, MAGNETIC FIELDS, AND WIND COLLISIONS
- J. Kastner, R. Montez, U. A. D. Madrid
- Physics
- 25 April 2012
We present an overview of the initial results from the Chandra Planetary Nebula Survey (ChanPlaNS), the first systematic (volume-limited) Chandra X-Ray Observatory survey of planetary nebulae (PNe)…
Turbulence Driven by Outflow-blown Cavities in the Molecular Cloud of NGC 1333
- A. Quillen, Stephen L. Thorndike, N. Ridge
- Physics
- 7 March 2005
Outflows from young stellar objects (YSOs) have been identified as a possible source of turbulence in molecular clouds. To investigate the relationship between outflows, cloud dynamics, and…

The Magnetohydrodynamic Kelvin-Helmholtz Instability: A Two-dimensional Numerical Study
- A. Frank, T. Jones, D. Ryu, J. B. Gaalaas
- Physics
- 23 October 1995
Using a new numerical code we have carried out two-dimensional simulations of the nonlinear evolution of unstable sheared magnetohydrodynamic flows. We considered two cases: a strong magnetic field…
On the Planet and the Disk of COKU TAURI/4
- A. Quillen, E. Blackman, A. Frank, P. Varniere
- Physics, Geology
- 20 June 2004
Spitzer observations of the young star CoKu Tau/4 reveal a disk with a 10 AU hole that is most likely caused by a newly formed planet. Assuming that the planet opened a gap in the viscous disk, we…
