Source-derived summary

HD 205739 is a yellow-white hued star in the southern constellation of Piscis Austrinus, positioned near the western constellation boundary with Microscopium. It has the proper name Sāmaya, which was selected in the NameExoWorlds campaign by Sri Lanka, during the 100th anniversary of the IAU. Sāmaya (සාමය) means peace in the Sinhalese language.

With an apparent visual magnitude of 8.56, this star requires a small telescope to view. It is located at a distance of approximately 303 light-years from the Sun based on stellar parallax, and is drifting further away with a radial velocity of +9.7 km/s. This star has an absolute magnitude of 3.42.

HD 205739 is an ordinary F-type main-sequence star with a stellar classification of F7 V. This indicates that, like the Sun, it is generating energy through core hydrogen fusion. The star is 2.8 billion years old with an inactive chromosphere and is spinning with a projected rotational velocity of 4 km/s. It has 1.3 times the mass of the Sun and 1.6 times the Sun's radius. The abundance of iron is 60% greater than in the Sun, suggesting a higher metallicity. The star is radiating 3.5 times the luminosity of the Sun from its photosphere at an effective temperature of 6,276 K.

A Jupiter-like planet has been detected in an eccentric orbit around this star via Doppler spectroscopy.

Editorial summary

The public source identifies “HD 205739” as star. This brief keeps that definition visible, then builds a research path around star.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current 223-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with star providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “HD 205739”, the useful work is to connect “star” to the records capable of establishing context and consequence.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 12, 2026. The linked authority identifier is Q2088803. None of the 0 selected statements returned an explicit reference.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
