- HD_13189 abstract "HD 13189 is an 8th magnitude star in Triangulum constellation.In 2005, a planetary companion or brown dwarf was announced in orbit around this star. At the time, the parallax estimate was 0.54 ± 0.93 mas, which would suggest a distance of 6,040 ly (1,850 pc) with a high margin of error. In 2007, van Leeuwen published a revised parallax measurement of 1.78 ± 0.73, which corresponds to a distance of 1,830 ly (560 pc) with a smaller but still significant margin of error.It has a spectral classification of K1II-III, making it a giant star that has evolved away from the main sequence. The mass is 2–7 times the Sun, while measurements of the star's radius give estimates of 45.5 or 50.4 solar radii. This mass range is typical of a B-type main sequence star, suggesting the star belong to stellar class B when it was on the main sequence. The atmosphere of the star displays short period radial velocity variations with a primary period of 4.89 days. This behavior is typical for giant K-type stars such as this and it is not the result of a close-orbit planetary companion.".
