Polarization of asteroid (387) Aquitania: the newest member of a class of large inversion angle asteroids
Joseph Masiero, Alberto Cellino
We present new imaging polarimetric observations of two Main Belt asteroids, (234) Barbara and (387) Aquitania, taken in the first half of 2008 using the Dual-Beam Imaging Polarime…
Extended Commissioning and Calibration of the Dual-Beam Imaging Polarimeter
Joseph Masiero, Klaus Hodapp, David Harrington +1
In our previous paper (Masiero et al. 2007) we presented the design and initial calibrations of the Dual-Beam Imaging Polarimeter (DBIP), a new optical instrument for the Universit…
Commissioning of the Dual-Beam Imaging Polarimeter for the UH 88-inch telescope
Joseph Masiero, Klaus Hodapp, Dave Harrington +1
In this paper we present the design, calibration method, and initial results of the Dual-Beam Imaging Polarimeter (DBIP). This new instrument is designed to measure the optical pol…
Efficient intra- and inter-night linking of asteroid detections using kd-trees
Jeremy Kubica, Larry Denneau, Tommy Grav +7
The Panoramic Survey Telescope And Rapid Response System (Pan-STARRS) under development at the University of Hawaii's Institute for Astronomy is creating the first fully automated…
Preliminary Results from Detector-Based Throughput Calibration of the CTIO Mosaic Imager and Blanco Telescope Using a Tunable Laser
Christopher W. Stubbs, Sara K. Slater, Yorke J. Brown +7
We describe the scientific motivation for achieving photometric precision and accuracy below the 1% level, and we present a calibration philosophy based on using calibrated detecto…
The Nature of Weak MgII Absorbing Structures
Nikola Milutinovic, Jane R. Rigby, Joseph R. Masiero +3
We consider geometries and possible physical models for weak low ionization absorbers based on the relative incidence of low and high ionization absorption systems. We found a tota…
