History of observations

A designation of this star, used in "Discovery Name" column of Table 4 of Kirkpatrick et al. (2012), is Strb. 1611. [17] This name was taken from van de Kamp (1930) [18] . The origin of this designation is not explained in these articles. Anyway, it is not Struve's 1827 catalogue of binary stars, since for this catalogue another prefix ("Σ") is used, for example, "Σ 2398", [17] [18] and real Σ 1611 is located in completely different part of the sky. [24] Also, Gliese 205 is not a binary star. In the paper, published in Annales de l'Observatoire de Strasbourg in 1926 an object "N** Strasb. 1611" in "5h" sections was listed, [25] so, possibly, this designation relates to the Observatory of Strasbourg. Possibly, it is the "Catalogue de Strasbourge" of 8204 stars, published in Volume 4 of Annales de l'Observatoire de Strasbourg in 1912 — a part of international Astronomische Gesellschaft Katalog (AGK), [25] made by various observatories by 1912. If so, then there are earlier designations).

Of the other designations, the earliest one is W. B. V. 592 or Weisse I, 5h 592 (Maximiliano Weisse; Friedrich Bessel, Positiones mediae stellarum fixarum I, 1846). [14] This catalogue was based on observations, made by Bessel in 1821–1833 and published in 1822–1838 in Astronomische Beobachtungen auf der königlichen Universitäts-Sternwarte in Königsberg as "Beobachtungen der Sterne, nach Zonen der Abweichung angestellt". Gliese 205, probably, was observed on January 8, 1823 in zone 140 (see the 9th abtheilung (1824), page 55, 2nd column, 33rd string). [26]

Search for planets

In a 2019 preprint, two candidate planets were detected using the radial velocity method, both Neptune-mass with orbital periods of 17 and 270 days. [27] However, a study of this star in 2023 found no evidence of planets, and determined a stellar rotation period of 34.4 days. [5]

Gliese 65, also known as Luyten 726-8, is a binary star system that is one of Earth's nearest neighbors, at 8.8 light-years from Earth in the constellation Cetus. The two component stars are both flare stars with the variable star designations BL Ceti and UV Ceti.

Gliese 436 is a red dwarf located 31.9 light-years away in the zodiac constellation of Leo. It has an apparent visual magnitude of 10.67, which is much too faint to be seen with the naked eye. However, it can be viewed with even a modest telescope of 2.4 in (6 cm) aperture. In 2004, the existence of an extrasolar planet, Gliese 436 b, was verified as orbiting the star. This planet was later discovered to transit its host star.

Gliese 1 is a red dwarf in the constellation Sculptor, which is found in the southern celestial hemisphere. It is one of the closest stars to the Sun, at a distance of 14.2 light years. Because of its proximity to the Earth it is a frequent object of study and much is known about its physical properties and composition. However, with an apparent magnitude of about 8.6 it is too faint to be seen with the naked eye.

Gliese 674(GJ 674) is a small red dwarf star with an exoplanetary companion in the southern constellation of Ara. It is too faint to be visible to the naked eye, having an apparent visual magnitude of 9.38 and an absolute magnitude of 11.09. The system is located at a distance of 14.8 light-years from the Sun based on parallax measurements, but is drifting closer with a radial velocity of −2.9 km/s. It is a candidate member of the 200 million year old Castor stream of co-moving stars.
