This pulsar was discovered in the High Time Resolution Universe survey and it belongs to the class of “redback” systems. The minimum estimated mass for the companion of J1431-4715 is, indeed, 0.13 M<SUB>☉</SUB>. Thanks to multi-frequency observations, obtained at the 64 m Parkes radio telescope, we note that the magnitude and the duration of the eclipse delay depend upon the observing frequency.STAMPAenConference paper10.1088/1742-6596/956/1/0120042-s2.0-85042256929000454921900004https://iopscience.iop.org/article/10.1088/1742-6596/956/1/012004/meta2018JPhCS.956a2004MFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation::PE9_6 Stars and stellar systems
