HD 28700 (HR 1433) is a solitary star in the southern constellation Caelum. It has an apparent magnitude of 6.12, [2] making it visible to the naked eye under ideal conditions. Parallax measurements place the object at a distance of 384 light years [1] and is currently receding with a heliocentric radial velocity of 10.7 km/s . [5]
HD 28700 has a stellar classification of K1 III, [3] indicating that it is a red giant. It has three times the Sun's mass and has expanded to ten times its radius. It radiates at 56 times the Sun's luminosity from its swollen photosphere at an effective temperature of 4,760 K , [7] giving it an orange hue. HD 28700 has a projected rotational velocity too low to be measured accurately due to it being less than 1 km/s . [9] HD 28700 has 120% the abundance of iron relative to the Sun. [8] At a modeled age of 377 million years, HD 28700 is on the red giant branch fusing hydrogen in a shell around an inert helium core. [1]
HD 131551 is a solitary star in the southern constellation Apus. It has an apparent magnitude of 6.19, allowing it to be faintly seen with the naked eye under ideal conditions. Located 526 light years away, the object is approaching the Sun with a heliocentric radial velocity of 7.6 km/s.
HD 152010 is a solitary star in the southern circumpolar constellation Apus. It has an apparent magnitude of 6.48, placing it near the max visibility for the naked eye. Located 1,006 light yearsaway, the object is approaching the Solar System with a heliocentric radial velocity of −15 km/s.
HD 24479, also designated as HR 1204, is a solitary, bluish-white hued star located in the northern circumpolar constellation Camelopardalis.
