HD 108541，又名CD-38 7753，SAO 203508、HR 4748，是一颗恒星，视星等为5.44，位于銀經298.05，銀緯23.61，其B1900.0坐标为赤經12h 23m 3.3s，赤緯-38° 23.61′ 15″。 HD 108541, also known by its Bayer designation u Centauri is a star located in the constellation Centaurus, It is also known as HR 4748. The apparent magnitude of the star is about 5.4, meaning it is only visible to the naked eye under excellent viewing conditions. Its distance is about 440 light-years (140 parsecs), based on its parallax measured by the Hipparcos astrometry satellite. The spectral type of HD 108541 is B8/9V, meaning it is a late B-type main sequence star. These types of stars are a few times more massive than the Sun, and have effective temperatures of about 10,000 to 30,000 K. HD 108541 is just under 3 times more massive than the Sun and has a temperature of about 11,000 K. HD 108541 (u Centauri) é uma estrela na constelação de Centaurus. Tem uma magnitude aparente visual de 5,44, sendo visível a olho nu em locais com pouca poluição luminosa. Com base em medições de paralaxe pelo satélite Gaia, está localizada a aproximadamente 440 anos-luz (135 parsecs) da Terra. HD 108541 är en ensam stjärna belägen i den norra delen av stjärnbilden Kentauren som också har Bayer-beteckningen u Centauri. Den har en skenbar magnitud av ca 5,45 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 7,5 mas, beräknas den befinna sig på ett avstånd på ca 440 ljusår (ca 134 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 5 km/s.

HD 108541 är en ensam stjärna belägen i den norra delen av stjärnbilden Kentauren som också har Bayer-beteckningen u Centauri. Den har en skenbar magnitud av ca 5,45 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 7,5 mas, beräknas den befinna sig på ett avstånd på ca 440 ljusår (ca 134 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 5 km/s. HD 108541, also known by its Bayer designation u Centauri is a star located in the constellation Centaurus, It is also known as HR 4748. The apparent magnitude of the star is about 5.4, meaning it is only visible to the naked eye under excellent viewing conditions. Its distance is about 440 light-years (140 parsecs), based on its parallax measured by the Hipparcos astrometry satellite. The spectral type of HD 108541 is B8/9V, meaning it is a late B-type main sequence star. These types of stars are a few times more massive than the Sun, and have effective temperatures of about 10,000 to 30,000 K. HD 108541 is just under 3 times more massive than the Sun and has a temperature of about 11,000 K. HD 108541 (u Centauri) é uma estrela na constelação de Centaurus. Tem uma magnitude aparente visual de 5,44, sendo visível a olho nu em locais com pouca poluição luminosa. Com base em medições de paralaxe pelo satélite Gaia, está localizada a aproximadamente 440 anos-luz (135 parsecs) da Terra. u Centauri é uma estrela de classe B da sequência principal com um tipo espectral de B8V. Tem uma massa equivalente a 3,2 vezes a massa solar e está brilhando com 150 vezes a luminosidade solar. Sua fotosfera irradia essa energia a uma temperatura efetiva de 10 690 K, dando à estrela a coloração azul-branca típica de estrelas de classe B. Com uma idade de 175 milhões de anos, é estimado que já tenha passado por 80% do seu tempo de sequência principal. Não possui estrelas companheiras conhecidas.
