NGC 602

Constellation: Hydrus

NGC 602 is a young star cluster in the Small Magellanic Cloud (constellation Hydrus). It is surrounded by the H-II region LHA 115 N90, which is populated with even younger pre-main sequence stars. Link to interactive sky chart.

NGC 602 contains three main condensation of stars. Left: the central core NGC 602a and the compact NGC 602b about 100 arc-seconds to the NNW (JWST image). Right: The looser NGC 602c 11 arc-minutes to the NE of NGC 602a.

7.5 arc-minutes East of NGC 602, one can see the supernova remnant (SNR) MCSNR J0127-7332 surrounding the high mass X-ray binary SXP1062. The optical counterpart of the X-ray source is the emission-line star 2dFS 3831 of spectral type B0-0.5(III)e+. Hence this is a Be/X-ray binary (Be-XRB). The SNR is linked to the supernova explosion that created the X-ray pulsar. It is 20’000-40’000 years old. (Link to publication)

LHA 115 N89 is an H-II region located 20 arc-minutes ENE of NGC 602. It surrounds the star association Lindsay 104.
