Demonstration of Plate Analysis, an algorithm for precise relative astrometry
Ryou Ohsawa, Daisuke Kawata, Takafumi Kamizuka +3
Astrometry plays a crucial role in understanding the structure, dynamics, and evolution of celestial objects by providing precise measurements of their positions and motions. We pr…
JASMINE image simulator for high-precision astrometry and photometry
Takafumi Kamizuka, Hajime Kawahara, Ryou Ohsawa +23
JASMINE is a Japanese planned space mission that aims to reveal the formation history of our Galaxy and discover habitable exoEarths. For these objectives, the JASMINE satellite pe…
JASMINE: Near-Infrared Astrometry and Time Series Photometry Science
Daisuke Kawata, Hajime Kawahara, Naoteru Gouda +86
Japan Astrometry Satellite Mission for INfrared Exploration (JASMINE) is a planned M-class science space mission by the Institute of Space and Astronautical Science, the Japan Aero…
Faint debris disk peering through superflare light echo
Ko Arimatsu, Takafumi Kamizuka
We present the detectability of strong mid-infrared (MIR) light echoes from faint debris disks illuminated by bright superflares of M-dwarf stars. Circumstellar dust grains around…
Long-Term Near-Infrared Brightening of Non-Variable OH/IR Stars
Takafumi Kamizuka, Yoshikazu Nakada, Kenshi Yanagisawa +8
Non-variable OH/IR stars are thought to have just left the asymptotic giant branch (AGB) phase. In this conventional picture, they must still show strong circumstellar extinction c…
"Slow-Scanning" in Ground-Based Mid-Infrared Observation
Ryou Ohsawa, Shigeyuki Sako, Takashi Miyata +8
Chopping observations with a tip-tilt secondary mirror have conventionally been used in ground-based mid-infrared observations. However, it is not practical for next generation lar…
ANIR : Atacama Near-Infrared Camera for the 1.0-m miniTAO Telescope
Masahiro Konishi, Kentaro Motohara, Ken Tateuchi +35
We have developed a near-infrared camera called ANIR (Atacama Near-InfraRed camera) for the University of Tokyo Atacama Observatory 1.0m telescope (miniTAO) installed at the summit…
Ground-based Pa Narrow-band Imaging of Local Luminous Infrared Galaxies I: Star Formation Rates and Surface Densities
Ken Tateuchi, Masahiro Konishi, Kentaro Motohara +33
Luminous infrared galaxies (LIRGs) are enshrouded by a large amount of dust, produced by their active star formation, and it is difficult to measure their activity in the optical w…
