LHS 1723 is a nearby red dwarf star of spectral type M4.0, located in constellation Eridanus at 17.4 light-years from Earth.[1]

History of observations

The discovery name of this star is LP 656-38,[5] which indicates that its discovery was published between 1963 and 1981 in University of Minnesota, Minneapolis.[6] "LP" means "Luyten, Palomar".

LHS 1723 is known at least from 1979, when catalogues of high proper motion objects LHS and NLTT were published by Willem Jacob Luyten, and this object was included to these catalogues.[3][2]

Distance measurement

In 1982 Wilhelm Gliese published photometric distance of LHS 1723 (0.161 mas),[7] and in 1991 it was included to the 3rd preliminary version of catalogue of nearby stars by Gliese and Jahreiss as NN 3323 (also designated as GJ 3323) with photometric parallax 163.0±26.0 mas.[4]

Its trigonometric parallax remained unknown until 2006, when it was published by RECONS team. The parallax was 187.92±1.26 mas.[1]
