Second-timescale Glints from Satellites and Space Debris Detected with Tomo-e Gozen
Masaomi Tanaka, Ichiro Takahashi, Naoki Yoshida +17
A search for second-timescale optical transients is one of the frontiers of time-domain astronomy. However, it has been pointed out that reflections of sunlight from Earth-orbiting…

The effect of stellar evolution on dispersal of protoplanetary disks: Disk fraction in star-forming regions
Ayano Komaki, Naoki Yoshida
We study the effect of stellar evolution on the dispersal of protoplanatary disks by performing one-dimensional simulations of long-term disk evolution. Our simulations include vis…
