Abstract
There is mounting evidence for triplet superconductivity in the recently discovered skutterudite compound PrOs4Sb12. In this work, we propose nodal order parameters for the A- and B-phases of this superconductor which are consistent with angle dependent magnetothermal conductivity measurements and with low-temperature thermal conductivity data in the range T > 150 mK. The quasiparticle density of states and the thermal conductivity kappazz are derived within the quasiclassical approximation.
