HR 5401 is a star in the constellation Lupus. Its apparent magnitude is 5.83. HR 5401 is the primary component of a multiple-star system.

HR 297 is a solitary star in the northern circumpolar constellation of Cassiopeia. It has an apparent visual magnitude of 5.8, making it faintly visible to the naked eye from dark suburban skies. Parallax measurements with the Hipparcos spacecraft put this system at a distance of roughly 263 light years.This is an F-type main sequence star with a stellar classification of F7V. Because of the stability of this star, it is used as a standard in the photometric WBVR system. The angular diameter of this star has been measured directly using the CHARA Array, yielding an estimate of 4.5 times the diameter of the Sun. Stellar models suggest a mass equal to about twice that of the Sun, with 25 times the Sun's luminosity.This is a young star with an estimated age of 1.3 billion years. It is rotating rapidly, with a projected rotational velocity of 42 km/s. The abundance of elements other than hydrogen and helium is about the same as that in the Sun. The effective temperature of the stellar atmosphere is 6,089 K, giving it the yellow-white hued glow of an F-type star.This star has been examined for the presence of an infrared excess, but no statistically significant amount was detected. The detection of such an excess can indicate the presence of a dusty circumstellar disk.

HR 5171, also known as V766 Centauri, is a triple star system in the constellation Centaurus, around 12,000 light years from Earth. It is either a red supergiant or recent post-red supergiant yellow hypergiant, and one of the largest known stars. Its diameter is uncertain but likely to be around either 1300 or 1500 times that of the Sun. It is a contact binary, sharing a common envelope of material with a smaller yellow star, the two orbiting each other every 1,304 ± 6 days.

HR 3384 (11 G. Pyxidis) is solitary star in the southern constellation of Pyxis. It has an apparent magnitude of 6.38, indicating it is faintly visible to the naked eye. Based on the Bortle scale, the star can be viewed from dark rural skies. Astrometric measurements of the star by the Hipparcos spacecraft, give an estimated distance of about 40 light-years (12 parsecs) from Earth. It is moving away from the Sun with a radial velocity of +81.91.This star is lower in mass than the Sun at around 75%, and has just 85% of the Sun's radius. The spectrum matches a spectral class G9V, indicating that this is a G-type main sequence star that is generating energy through the nuclear fusion of hydrogen at its core. The star is radiating 44% of the Sun's luminosity from its photosphere at an effective temperature of 5,290 K. It is about six billion years old and is rotating slowly with a period of around 40 days. Surface magnetic activity has been detected with a periodic cycle of 3,050+558−408 days. HR 3384 has been examined for evidence of a circumstellar debris disk or planets, but, as of 2012, none have been discovered.

HR 5361

HR 273 is a chemically peculiar spectroscopic binary system in the northern circumpolar constellation of Cassiopeia. It has an apparent visual magnitude of 5.9 making it faintly visible to the naked eye from dark suburban skies. Parallax measurements with the Hipparcos spacecraft put this system at a distance of roughly 350 light years.The primary, HR 273 A, is an Ap star and the secondary is an Am star, making this a very unusual binary system.

HR 4049, also known as HD 89353 and AG Antliae, is a post-asymptotic-giant-branch star in the constellation Antlia. A very metal-poor star, it is surrounded by a thick unique circumbinary disk enriched in several molecules. With an apparent magnitude of 5.53, the star can readily be seen under ideal conditions. The star, located approximately 813 parsecs (2,650 ly) distant, has been found to be a binary star; however, likely the most unique feature about this star is its peculiar spectrum. The star appears, based on its spectrum in the Balmer series, to be a blue supergiant, although in reality it is an old low-mass star on the post-AGP phase of its life. The star is also undergoing intense mass-loss and is a unique variable, ranging between magnitudes 5.29 and 5.83 with a period of 429 days

The primary is a F-type main sequence star with an apparent magnitude of +4.75. The secondary is most likely a helium white dwarf with 0.47 times the mass of the Sun. Mass transfer from the white dwarf progenitor has given the primary the spectral signature of a blue straggler that appears much younger than its actual age of about 10 billion years.

HR 515 is an A-type variable star of δ Scuti type with a period of 0.219 days and an amplitude of 0.02 in visual magnitude. Despite its Flamsteed designation of 3 Arietis (3 Ari), the star is actually located in the constellation Pisces near the border of Aries. Its apparent magnitude is 6.54–6.59. The star has the variable star designation VY Piscium (VY Psc).

The primary has a magnetic field of 65 gauss, amongst the weakest seen in any Ap star. The magnetic field in the secondary is too weak to detect.Component A has a spectral type of A0 III, and has unusually strong lines of strontium, chromium, and europium so it is known as a SrCrEu star. Although some spectral lines of the secondary star can be clearly distinguished, its spectral type cannot be clearly assigned. It is thought to be a late class A star, cooler than the primary. The primary star has been rotationally braked so that its rotational period closely matches its orbital period.
