Scientific paper

We recently reported the discovery of a faint proper motion companion to a nearby white dwarf using 4.5um images from the Spitzer Space Telescope. We estimated a mass of 7 Jupiter masses and a temperature of 300 K for this companion if it has the distance and age of the primary, which would make it the coolest object directly observed outside of the solar system. Since our publication of these initial data, we have obtained images at additional wavelengths with the Very Large Telescope and the Spitzer Space Telescope to confirm its common proper motion and to better constrain its temperature. We present these unpublished results, and discuss the implications for direct imaging surveys for objects near 300 K and below.
