Abstract
Abstract 2MASS J050051.85−093054.9 is the closest known low-mass helium-core white dwarf in a binary system. We used three high-band international Low-Frequency Array stations to perform a targeted search for a pulsar companion, reaching sensitivities of ∼3 mJy for a 10 ms pulsar at a DM = 1 pc cm−3. No pulsed signal was detected, confidently excluding the presence of a detectable radio pulsar in the system.
