Variation of Galactic Bar Length with Amplitude and Density as Evidence for Bar Growth over a Hubble Time
Bruce G. Elmegreen, Debra Meloy Elmegreen, Johan H. Knapen +3
K_s-band images of 20 barred galaxies show an increase in the peak amplitude of the normalized m=2 Fourier component with the R_25-normalized radius at this peak. This implies that…
HE 1113-0641: The Smallest Separation Gravitational Lens Identified by a Ground-based Optical Telescope
Jeffrey A. Blackburne, Lutz Wisotzki, Paul L. Schechter
The Hamburg/ESO quasar HE 1113-0641 is found to be a quadruple gravitational lens, based on observations with the twin 6.5m Magellan telescopes at the Las Campanas Observatory, and…
The orbits of the quadruple star system 88 Tau A from PHASES differential astrometry and radial velocity
Benjamin F. Lane, Matthew W. Muterspaugh, Francis C. Fekel +7
We have used high precision differential astrometry from the Palomar High-precision Astrometric Search for Exoplanet Systems (PHASES) project and radial velocity measurements cover…
Interferometric Observations of V1663 Aquilae (Nova Aql 2005)
B. F. Lane, A. Retter, J. A. Eisner +3
We have resolved the classical nova V1663 Aql using long-baseline near-IR interferometry covering the period from 5--18 days after peak brightness. We directly measure the shape an…
Masses, Luminosities, and Orbital Coplanarities of the mu Orionis Quadruple Star System from PHASES Differential Astrometry
Matthew W. Muterspaugh, Benjamin F. Lane, Francis C. Fekel +6
mu Orionis was identified by spectroscopic studies as a quadruple star system. Seventeen high precision differential astrometry measurements of mu Ori have been collected by the Pa…
The Burst Spectra of EXO 0748-676 during a Long 2003 XMM-Newton Observation
J. Cottam, F. Paerels, M. Méndez +4
Gravitationally redshifted absorption lines from highly ionized iron have been previously identified in the burst spectra of the neutron star in EXO 0748-676. To repeat this detect…
