اچ دی ۴۳۵۸۷ ( انگلیسی: HD 43587 ) یک منظومه ستاره ای است که تقریباً ۶۳ سال نوری از ما فاصله دارد و در صورت فلکی شکارچی قرار دارد و با چشم غیرمسلح قابل مشاهده است. این منظومه از چهار ستاره مجزا تشکیل شده است که دو به دو کاملاً از هم جدا شده اند که یک سیستم چهارگانه را تشکیل می دهند.
↑ No value for HD 43587 Aa's radial velocity with correction for the binary orbit seems to be present in literature, so it must be derived by other means. At BJD 2452003. 7636, The Keck/HIRES relative radial velocity in orbital fitting was at approximately - 2. 75 km/s. At BJD 2451981. 6466, The Kitt Peak 0. 9 AFT absolute radial velocity was 6. 21 km/s, with an approximate error of 0. 1 km/s. 6. 21 km/s - - 2. 75 km/s = 8. 96 km/s, which should be approximately the star's radial velocity. Additionally, an orbital fit including publicly available data from the ELODIE archive finds a value of 8. 97 ± 0. 03 km/s for the star's intrinsic radial velocity, confirming the value. ↑ This ( dynamical ) mass is discrepantly large when compared with the derived atmospheric parameters and the photometric mass of 0. 54 ± 0. 05 M☉ derived in the same paper. ↑ SIMBAD erroneously lists NLTT 16333 and NAME GJ 231. 1 BC as different objects due to the co - ordinates in Pravdo et al. ( 2006 ) being seemingly incorrect, but they are in fact the same.
