High Resolution Infrared Imaging & Spectroscopy of the Z Canis Majoris System During Quiescence & Outburst
Sasha Hinkley, Lynne Hillenbrand, Ben R. Oppenheimer +21
We present adaptive optics photometry and spectra in the JHKL-bands along with high spectral resolution K-band spectroscopy for each component of the Z Canis Majoris system. Our hi…
Robo-AO: An Autonomous Laser Adaptive Optics and Science System
Christoph Baranec, Reed Riddle, A. N. Ramaprakash +15
Robo-AO, a fully autonomous, laser guide star adaptive optics and science system, is being commissioned at Palomar Observatory's 60-inch telescope. Here we discuss the instrument,…
Constraining mass ratio and extinction in the FU Orionis binary system with infrared integral field spectroscopy
Laurent Pueyo, Lynne Hillenbrand, Gautam Vasisht +15
We report low resolution near infrared spectroscopic observations of the eruptive star FU Orionis using the Integral Field Spectrograph Project 1640 installed at the Palomar Hale t…
Millions of Multiples: Detecting and Characterizing Close-Separation Binary Systems in Synoptic Sky Surveys
Emil Terziev, Nicholas M. Law, Iair Arcavi +15
The direct detection of binary systems in wide-field surveys is limited by the size of the stars' point-spread-functions (PSFs). A search for elongated objects can find closer comp…
Developments in high-density Cobra fiber positioners for the Subaru Telescope's Prime Focus Spectrograph
Charles D. Fisher, David F. Braun, Joel V. Kaluzny +4
The Prime Focus Spectrograph (PFS) is a fiber fed multi-object spectrometer for the Subaru Telescope that will conduct a variety of targeted surveys for studies of dark energy, gal…
The metrology cameras for Subaru PFS and FMOS
Shiang-Yu Wang, Yen-Shan Hu, Chi-Hung Yan +11
The Prime Focus Spectrograph (PFS) is a new multi-fiber spectrograph on Subaru telescope. PFS will cover around 1.4 degree diameter field with ~2400 fibers. To ensure precise posit…
