Updating the SCExAO/CHARIS polarimetric calibration following the Nasmyth beam-switcher upgrade
Thomas McIntosh, Manxuan Zhang, Briley L. Lewis +18
Subaru/SCExAO/CHARIS enables near-infrared integral field spectropolarimetry. Quantitative polarimetry is useful for a variety of science cases, particularly measurements related t…
Analysis of Laser-Satellite Deconfliction for Astronomical Observatories
Christoph Baranec, Reed Riddle, Yuhei Takagi +1
We present an analysis of laser-satellite deconfliction across three astronomical laser observatories for right ascension and declination targets and fixed azimuth and elevation ra…
Prime Focus Spectrograph on the Subaru Telescope: Overview of Science Operations
Masayuki Tanaka, Akira Arai, Wanqiu He +30
The paper presents the science operation framework for Prime Focus Spectrograph (PFS or 'Onohi'ula in its Hawaiian name) installed at the 8.2m Subaru Telescope on the summit of Mau…
Chromospheric Mg I Emission Lines of Pre-Main-Sequence Stars
Mai Yamashita, Yoichi Itoh, Yuhei Takagi
To reveal details of the internal structure, the relationship between chromospheric activity and the Rossby number has been extensively examined for main-sequence stars. For active…
