A Possible Indication of Metallic Iron in White Dwarf Dusty Disks from their "Dirtiness"
Ayaka Okuya, Satoshi Okuzumi, Aki Takigawa +1
Polluted white dwarfs provide unique constraints on the elemental compositions of planetary bodies. The tidal disruption of accreting bodies is thought to form circumstellar dusty…
Detecting water ice and vapor disks originating from icy planetary bodies around white dwarfs with future PRIMA observations
Ayaka Okuya, Hideko Nomura
Observations of atmospheres of polluted white dwarfs provide insights into the elemental composition of accreted exoplanets and exo-asteroids. However, they poorly constrain the ab…
Modeling the Evolution of Silicate/Volatile Accretion Discs around White Dwarfs
Ayaka Okuya, Shigeru Ida, Ryuki Hyodo +1
A growing number of debris discs have been detected around metal-polluted white dwarfs. They are thought to be originated from tidally disrupted exoplanetary bodies and responsible…
Constraining the Bulk Composition of Disintegrating Exoplanets Using Combined Transmission Spectra from JWST and SPICA
Ayaka Okuya, Satoshi Okuzumi, Kazumasa Ohno +1
Disintegrating planets are ultra-short-period exoplanets that appear to have a comet-like dust tail. They are commonly interpreted as low-mass planets whose solid surface is evapor…
Effects of a Binary Companion Star on Habitability of Tidally Locked Planets around an M-type Host Star
Ayaka Okuya, Yuka Fujii, Shigeru Ida
Planets in the "Habitable Zones" around M-type stars are important targets for characterization in future observations. Due to tidal-locking in synchronous spin-orbit rotations, th…
