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 LOFAR 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 $\cdot$ cm $^{-3}$ . No pulsed signal was detected, confidently excluding the presence of a detectable radio pulsar in the system.
