HIP 13962 – THE POSSIBLE FORMER MEMBER OF BINARY SYSTEM WITH SUPERNOVA

The run away supergiant star HIP13962 (spectral type G0Ia) was recently pointed as a possible former binary companion of young pulsar PSRJ0826+2637. The spectraof HIP13962 wereo btained in Haute-Provence observatory (France), in Bohuynsan observatory (Korea), and also in NARIT (Thailand) with1.9, 1....
