  • HD 201507, also designated HR 8095, is a white-hued star located in the equatorial constellation Equuleus. It has an apparent magnitude of 6.43, placing it near the limit for naked eye visibility. Parallax measurements place the object at a distance of 214 light years and it is currently drifting closer with a heliocentric radial velocity of −43 km/s. There have been disagreements in classifying the star's spectrum. Eugene A. Harlan found a spectral classification of F5 IV, indicating that it is a F-type subgiant that is evolving towards the red giant branch. On the other hand, Nancy Houk and Carrie Swift (1999) found a class of F2 V, indicating that it is still on the main sequence. HD 201507 has 1.45 times the mass of the Sun and a slightly enlarged radius of 2.2 R☉ due to its evolved state. It shines with a luminosity of about 9 L☉ from its photosphere at an effective temperature of 6,846 K. HD 201507 is slightly metal enriched, with a metallicity 123% that of the Sun. This star has a modest projected rotational velocity of 16 km/s and is estimated to be 1.21 billion years old, only a quarter the age of the Sun. (en)
  • HD 201507 är en ensam stjärna belägen i den södra delen av stjärnbilden Lilla hästen. Den har en skenbar magnitud av ca 6,43 och är mycket svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallax enligt Gaia Data Release 2 på ca 15,3 mas, beräknas den befinna sig på ett avstånd på ca 214 ljusår (ca 66 parsek) från solen. Den rör sig närmare solen med en heliocentrisk radialhastighet på ca -44 km/s. (sv)
