SIPS 1259-4336 is a nearby red dwarf star, located in constellation Centaurus at 11.8 light-years from Earth,[1] or, according unpublished RECONS trigonometric distance estimate, taken from website en.allexperts.com, at 25.4 light-years from Earth.[2]
History of observations
Discovery of SIPS 1259-4336 was published in 2005 by Deacon et al. The star was detected by its high proper motion from the Southern Infrared Proper Motion Survey (SIPS).[1]
Distance
There is an unpublished trigonometric distance estimate from website en.allexperts.com: Tom Whiting e-mailed Todd Henry from RECONS team around 2008, and the reply was that theirs unpublished distance estimate of SIPS 1259-4336 is 7.79±0.05 parsecs (25.4±0.2 light-years).[2]
As of May 2015, the only published distance estimates of SIPS 1259-4336 besides trigonometric parallax with high uncertainty from the star's discovery paper (276±41 mas[1]) is a parallax without error (~128 mas) from Burgasser et al. (2015). References of SIPS 1259-4336 data, including the parallax, were Deacon et al. (2005a) and T. Henry, priv. comm.[3]
