HD 98176 (original) (raw)
HD 98176 är en ensam stjärna belägen i den mellersta delen av stjärnbilden Kentauren. Den har en skenbar magnitud av ca 6,44 och kräver åtminstone en handkikare för att kunna observeras. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 9,5 mas, beräknas den befinna sig på ett avstånd på ca 344 ljusår (ca 105 parsek) från solen.

| dbo:abstract | HD 98176, also designated as HIP 55133 and rarely 22 G. Centauri, is a solitary, white hued star located in the southern constellation Centaurus. It has an apparent magnitude of 6.44, placing it near the limit for naked eye visibility. Based on parallax measurements from Gaia DR3, the object is estimated to be 348 light years distant. At its current distance, its brightness is diminished by 0.32 magnitudes due to interstellar dust. Pauzen et al. (2001) lists it as a potential λ Boötis star. This is an ordinary A-type main-sequence star with a stellar classification of A0 V. Pauzen et al. (2001) gives it a slightly cooler class of A1 Vn, which includes broad absorption lines due to rapid rotation. It has 2.5 times the mass of the Sun and double its radius. It radiates 28.3 times the luminosity of the Sun from its photosphere at an effective temperature of 9,774 K. Based on parameters derived from extinction in the Gaia passband, HD 98176 has an iron abundance 19% below solar levels.
