Geometric Distortion Calibration with Photo-lithographic Pinhole Masks for High-Precision Astrometry
Maxwell Service, Jessica R. Lu, Mark Chun +5
Adaptive optics (AO) systems deliver high-resolution images that may be ideal for precisely measuring positions of stars (i.e. astrometry) if the system has stable and well-calibra…
The Galactic Center: Improved Relative Astrometry for Velocities, Accelerations, and Orbits near the Supermassive Black Hole
Siyao Jia, Jessica R. Lu, S . Sakai +11
We present improved relative astrometry for stars within the central half parsec of our Galactic Center based on data obtained with the 10 m W. M. Keck Observatory from 1995 to 201…
Improved Image Quality Over 10' Fields with the `Imaka Ground Layer Adaptive Optics Experiment
Fatima Abdurrahman, Jessica R. Lu, Mark Chun +5
`Imaka is a ground layer adaptive optics (GLAO) demonstrator on the University of Hawaii 2.2m telescope with a 24'x18' field-of-view, nearly an order of magnitude larger than previ…
Individual, Model-Independent Masses of the Closest Known Brown Dwarf Binary to the Sun
E. Victor Garcia, S. Mark Ammons, Maissa Salama +18
At a distance of 2~pc, our nearest brown dwarf neighbor, Luhman 16 AB, has been extensively studied since its discovery 3 years ago, yet its most fundamental parameter -- the masse…
