AKARI/IRC 18 Micron Survey of Warm Debris Disks
Hideaki Fujiwara, Daisuke Ishihara, Takashi Onaka +11
Context. Little is known about the properties of the warm (Tdust >~ 150 K) debris disk material located close to the central star, which has a more direct link to the formation of…
The Absence of Cold Dust around Warm Debris Disk Star HD 15407A
Hideaki Fujiwara, Takashi Onaka, Satoshi Takita +5
We report Herschel and AKARI photometric observations at far-infrared (FIR) wavelengths of the debris disk around the F3V star HD 15407A, in which the presence of an extremely larg…
Silica-Rich Bright Debris Disk around HD 15407A
Hideaki Fujiwara, Takashi Onaka, Takuya Yamashita +5
We report an intriguing debris disk towards the F3V star HD 15407A, in which an extremely large amount of warm fine dust (~ 10^(-7) M_Earth) is detected. The dust temperature is de…
