About: HD 175541

An Entity of Type: star, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org:8891

HD 175541 is an 8th magnitude star with an exoplanetary companion in the constellation Serpens. It has the proper name Kaveh, which was selected by Iran during the NameExoWorlds campaign as part of the 100th anniversary of the IAU. Kaveh is one of the heroes of Shahnameh. The apparent visual magnitude of 8.02 is too faint for this star to be visible in the naked eye. It is located at a distance of approximately 424 light years from the Sun based on parallax measurements, and is drifting further away with a radial velocity of +20 km/s. Despite its distance, it was given the number 736 in the Gliese Catalogue of Nearby Stars.

  • HD 175541 is an 8th magnitude star with an exoplanetary companion in the constellation Serpens. It has the proper name Kaveh, which was selected by Iran during the NameExoWorlds campaign as part of the 100th anniversary of the IAU. Kaveh is one of the heroes of Shahnameh. The apparent visual magnitude of 8.02 is too faint for this star to be visible in the naked eye. It is located at a distance of approximately 424 light years from the Sun based on parallax measurements, and is drifting further away with a radial velocity of +20 km/s. Despite its distance, it was given the number 736 in the Gliese Catalogue of Nearby Stars. This is an evolved G-type star with a stellar classification of G6/8IV. The absolute magnitude of 2.54 places it 3.5 magnitudes above the comparable main sequence stars in the Sun's neighborhood, indicating that it is on the subgiant branch. When this intermediate-mass star was on the main-sequence, it was an A-type star. It is around three billion years old and is chromospherically inactive with low a projected rotational velocity of 0.5 km/s. The star has 1.45 times the mass and has expanded to 4.1 times the radius of the Sun. It is radiating ten times the luminosity of the Sun from its photosphere at an effective temperature of 5,093 K. In April 2007, a Jovian planet was found orbiting this star using the radial velocity method, from Lick and Keck Observatories in Mount Hamilton (California) and Mauna Kea (Hawai'i), United States.

  • Kaveh eller HD 175541 är en ensam stjärna belägen i den mellersta delen av stjärnbilden Ormen. Den har en skenbar magnitud av ca 8,02 och kräver åtminstone en stark handkikare eller ett mindre teleskop för att kunna observeras. Baserat på parallax enligt Gaia Data Release 2 på ca 7,7 mas, beräknas den befinna sig på ett avstånd på ca 424 ljusår (ca 130 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 20 km/s. (sv)
