This was achieved by observing the Doppler shift of the spectrum of Chalawan. [13] In addition, it may have disrupted the formation of terrestrial planets and reduced the delivery of water to any inner planets in the system. [7] The winning name was submitted by the Thai Astronomical Society of Thailand. [10] However, subsequent investigation of the data reduction techniques used suggests that the Hipparcos measurements are not precise enough to adequately characterise the orbits of substellar companions, and the true inclination of the orbit (and hence the true mass) are regarded as unknown.
