Location of gamma-ray Flare Emission in the Jet of the BL Lacertae Object OJ287 more than 14pc from the Central Engine
Ivan Agudo, Svetlana G. Jorstad, Alan P. Marscher +18
We combine time-dependent multi-waveband flux and linear polarization observations with sub-milliarcsecond-scale polarimetric images at lambda=7mm of the BL Lacertae-type blazar OJ…
Whole Earth Telescope Observations of the subdwarf B star KPD 1930+2752: A rich, short period pulsator in a close binary
M. D. Reed, S. L. Harms, S. Poindexter +58
KPD 1930+2752 is a short-period pulsating subdwarf B (sdB) star. It is also an ellipsoidal variable with a known binary period just over two hours. The companion is most likely a w…
Asymmetric Heating of the HR 4796A Dust Ring Due to Pericenter Glow
Margaret Moerchen, Laura Churcher, Charles Telesco +3
We have obtained new resolved images of the well-studied HR 4796A dust ring at 18 and 25 microns with the 8-meter Gemini telescopes. These images confirm the previously observed sp…
Two-photon Double Ionization of H in Intense Femtosecond Laser Pulses
Xiaoxu Guan, Klaus Bartschat, Barry I. Schneider
Triple-differential cross sections for two-photon double ionization of molecular hydrogen are presented for a central photon energy of 30 eV. The calculations are based on a fully…
The Nature of the Warm/Hot Intergalactic Medium I. Numerical Methods, Convergence, and OVI Absorption
Britton D. Smith, Eric J. Hallman, J. Michael Shull +1
We perform a series of cosmological simulations using Enzo, an Eulerian adaptive-mesh refinement, N-body + hydrodynamical code, applied to study the warm/hot intergalactic medium.…
The Solar Neighborhood. XXII. Parallax Results from the CTIOPI 0.9m Program: Trigonometric Parallaxes of 64 Nearby Systems with 0\farcs5 1\farcs0 yr (SLOWMO sample)
Adric R. Riedel, John P. Subasavage, Charlie T. Finch +7
We present trigonometric parallaxes of 64 stellar systems with proper motions between 0\farcs5 yr and 1\farcs0 yr from the ongoing RECONS (Research Consortium On Near…
