HD 1237 differs from the sun in that HD 1237 is much younger, has high metallicity, has much cooler temperature and is in a binary system. As of 2000, it has been confirmed that an extrasolar planet orbits the star.
HD 1237 (GJ 3021) is a bright (Vmag 6.58), Sun-like star (G8V) =. located about 17.5 pc from the Sun, in the southern constella-tion of Hydrus (Koen et al. 2010). This object is a relatively young ( 0.88 Gyr), chromospherically active, and confirmed exo-planet host star.
We analyse the magnetic activity characteristics of the planet-hosting Sun-like star, HD 1237, using HARPS spectro-polarimetric time-series data. We find evidence of rotational modulation of the magnetic longitudinal field measurements that is consistent with our ZDI analysis with a period of 7 days.
