HD 141943


HD 141943 is a young pre-main sequence G-type star with a circumstellar disk. Due to the similarity between HD 141943 and the Sun, it resembles what the Sun would have looked like during the epoch of terrestrial planet formation in Solar System history. Reconstruction of brightness maps of HD 141943 reveal a weak polar spot that changed little in latitude over the 4 year period in which it was observed. It also revealed significant amounts of low latitude features on HD 141943.
It is a potential excellent candidate for telescopes such as the Hubble Space Telescope, the Gemini Planet Imager and the Very-Large Telescope for follow-up observations of possible planet formation around HD 141943.

Magnetic field

The coronal [magnetic field] of HD 141943 is dominated by a dipole which shows evidence of a possible tilt. The star also has a high differential rotation, about 8 times the value of the magnetic features of the Sun and 5 times the brightness features. This makes it similar to K-type stars.
