A Spitzer White Dwarf Infrared Survey
F. Mullally, Mukremin Kilic, William T. Reach +4
We present mid-infrared photometry of 124 white dwarf stars with Spitzer Space Telescope. Objects were observed simultaneously at 4.5 and 8.0um with sensitivities better than 1 mJy…
Spitzer White Dwarf Planet Limits
F. Mullally, Ted von Hippel, D. E. Winget
We present preliminary limits on the presence of planets around white dwarf stars using the IRAC photometer on the Spitzer space telescope. Planets emit strongly in the mid-infrare…
The Mystery Deepens: Spitzer Observations of Cool White Dwarfs
Mukremin Kilic, Ted von Hippel, Fergal Mullally +4
We present 4.5m and 8m photometric observations of 18 cool white dwarfs obtained with the Spitzer Space Telescope. Our observations demonstrate that four white dwarfs with T_…
