Concordance, Etymology, History
This neutron star is named after the villain in the 1960 film The Magnificent Seven, as it was found in 2001[1] in a category of neutron stars that had formerly been called The Magnificent Seven [2][3]. These isolated neutron stars were known within 500 parsecs of Earth: the initially found set were the sources RX J1856.5-3754, RBS1556, RBS1223, RX J0806.4-4132, RX J0720.4-3125, RX J0420.0-5022 and MS 0317.7-6647.[4] These objects are also known under the names XDINS (X-ray Dim Isolated Neutron Stars) or simply XINS, the first of which was discovered by Walter et al. (1996)[5] and confirmed as neutron stars.
Mythology
IAU Working Group on Star Names
The name was discussed and approved by the IAU WGSN in 2026, following a proposal by the SIMBAD team. The star is also called 1RXS J141256.0+792204.
