Detection of the PSR J1741+1351 white dwarf companion with the Gran Telescopio Canarias

Abstract

We report detection of the binary companion to the millisecond pulsar J1741+1351 with the Gran Telescopio Canarias. The optical source position coincides with the pulsar coordinates and its magnitudes are g' = 24.84(5), r' = 24.38(4) and i' = 24.17(4). Comparison of the data with the white dwarf evolutionary models shows that the source can be a He-core white dwarf with a temperature of $\approx 6000$ K and a mass of $\approx 0.2$ M${}_{\odot }$. The latter is in excellent agreement with the companion mass obtained from the radio timing solution for PSR J1741+1351.
