Luhman and two colleagues used NASA’s infrared Spitzer Space Telescope to study WD 0806-661b, the companion of a faint white-dwarf star 63 light-years distant in the southern constellation Volans. WD 0806-661b emits only very feeble infrared emission at wavelengths no shorter than 4.5 microns. Luhman’s team bases the 80°F estimate on the …

Most of the new brown dwarfs found by Spitzer are thought to belong to the coolest known class of brown dwarfs, called T dwarfs, which are defined as being less than about 1,500 Kelvin (2,240 degrees Fahrenheit). One of the objects appears to be so cold that it may even be a long-sought Y dwarf — a proposed class of even colder .

Cool Stars Have Different Mix of Life-Forming Chemicals
They found that the cool stars, both the M-dwarf stars and brown dwarfs, showed no hydrogen cyanide at all, while 30 percent of the sun-like stars did. Perhaps ultraviolet light, which is much stronger around the sun-like stars, may drive a higher production of the hydrogen cyanide, said Pascucci.
