HD 143699 is a single star in the southern constellation of Lupus. It is a dim star but visible to the naked eye with an apparent visual magnitude of 4.90. Based upon an annual parallax shift of 9.2 mas, it is located around 350 light years away. It is most likely (90% chance) a member of the Upper Centaurus–Lupus subgroup of the Sco OB2 moving group.

  • 'HD 143699 är en ensam stjärna belägen i den mellersta delen av stjärnbilden Vargen. Den har en skenbar magnitud av ca 4,90 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallax enligt Gaia Data Release 2 på ca 9,2 mas, beräknas den befinna sig på ett avstånd på ca 350 ljusår (ca 108 parsek) från solen. Den ingår med 90 procent sannolikhet i övre Centaurus-Lupus, en undergrupp av rörelsegruppen Scorpii OB2. (sv)

  • HD 143699 is a single star in the southern constellation of Lupus. It is a dim star but visible to the naked eye with an apparent visual magnitude of 4.90. Based upon an annual parallax shift of 9.2 mas, it is located around 350 light years away. It is most likely (90% chance) a member of the Upper Centaurus–Lupus subgroup of the Sco OB2 moving group. This star has a stellar classification of B5/7 III/IV, suggesting it is an evolving star that is entering the giant stage. However, according to Zorec and Royer (2012) it is only 56% of the way through its main sequence lifespan. It is a chemically peculiar magnetic B star, showing an averaged quadratic field strength of (167.2±140.4)×10−3 T. Helium-weak, it displays an underabundance of helium in its spectrum. Radio emissions have been detected from this source. HD 143699 has 4.3 times the mass of the Sun and 4.4 times the Sun's radius. It has a high rate of spin with a projected rotational velocity of 123 km/s. The star is radiating 438 times the Sun's luminosity from its photosphere at an effective temperature of 14,521 K. (en)
