HD 93194 (HR 4205) is a star in the constellation Carina. Its apparent magnitude is 4.79. Its parent cluster is IC 2602.
HD 93607 is a B4 main sequence star, notable for "nebulous" absorption lines caused by its rapid rotation. [3] It is included on a list of the least variable stars amongst those observed by the Hipparcos satellite, with a possible variation less than 0.01 magnitudes. [10]
Chi Tauri, Latinised from χ Tauri, is a star system in the constellation of Taurus. Parallax measurements made by the Hipparcos spacecraft put it at a distance of about 291 light-years from Earth. The primary component has an apparent magnitude of about 5.4, meaning it is visible with the naked eye.
28 Andromedae is a Delta Scuti variable star in the constellation Andromeda. 28 Andromedae is the Flamsteed designation. It also bears the variable star name GN Andromedae. Its apparent magnitude is 5.214, varying by less than 0.1 magnitudes.
Alpha Chamaeleontis, Latinized from α Chamaeleontis, is a solitary star in the southern circumpolar constellation of Chamaeleon. It has an apparent visual magnitude of 4.06 and thus is bright enough to be seen with the naked eye. With an annual parallax shift of 51.12 mas, it is located 63.8 light years from the Sun. The star is drifting closer with a radial velocity of −13 km/s, and is predicted to come to within 47 light-years in 666,000 years.
Gliese 105 is a triple star system in the constellation of Cetus. It is located relatively near the Sun at a distance of 23.6 light-years. Despite this, even the brightest component is barely visible with the unaided eye (see Bortle scale). No planets have yet been detected around any of the stars in this system.
Lambda Caeli, Latinized from λ Caeli, is a star in the constellation Caelum. It is also known by its designations HD 30202 and HR 1518. This star is a challenge to view with the naked eye, having an apparent visual magnitude of 6.24. Based on parallax measurements, Lambda Caeli is known to be around 700 light-years distant from the Sun, but is drifting closer with a radial velocity of −4 km/s.
Tau1 Capricorni is a star in the constellation Capricornus. It has an apparent magnitude of 6.76, making it readily visible in binoculars, but not to the naked eye. Located approximately 750 light years from Earth, the star is receding with a heliocentric radial velocity of 18.5 km/s. Due to its location near the ecliptic, τ1 Cap can be occulted by the Moon and rarely planets.
HD 165259, also known as HR 6751 is a triple star system located in the southern circumpolar constellation of Apus. It has an apparent magnitude of 5.86, making it faintly visible to the naked eye Parallax measurements place the system at a distance of 138 light years, and it is currently receding with a heliocentric radial velocity of 13.1 km/s.
HD 36678 is single star in the northern constellation of Auriga. This star is dimly visible to the naked eye with an apparent visual magnitude of 5.83. It is located at a distance of approximately 840 light years from the Sun based on parallax.
HD 118508 is a suspected variable star in the northern constellation of Boötes. Its apparent magnitude may vary with an amplitude of 0.04, discovered during a search for small-amplitude red variables. It is a red giant about 552 light years away.
HD 128333 or CH Boötis is an irregular variable star in the northern constellation of Boötes. It is currently on the asymptotic giant branch of the HR diagram.
HD 135530 is a suspected variable star in the northern constellation of Boötes.
HD 112028 is an evolved star in the northern constellation of Camelopardalis. It has spectral peculiarities that have been interpreted as a shell, and also relatively weak magnesium and silicon lines. Its spectral class has been variously assigned between B9 and A2, and its luminosity class between a subgiant and bright giant.
HD 30442 is a solitary star in the northern circumpolar constellation Camelopardalis. It is faintly visible to the naked eye with an apparent magnitude of 5.47 and is estimated to be 403 light years away from the Solar System. The object has a heliocentric radial velocity of −37 km/s, indicating that it is drifting closer.
HD 93607 is a star in the constellation Carina. Its apparent magnitude is 4.87. Its parent cluster is IC 2602.
90 Tauri is a star in the zodiac constellation of Taurus, located 144 light-years away from the Sun. It is visible to the naked eye as a faint, white-hued star with an apparent visual magnitude of 4.27. 90 Tauri is a member of the Hyades cluster and is listed as a double star.
HD 39901 is an orange hued star located in the constellation Columba. It is also called HR 2069, which is the star's Bright Star Catalog designation. Eggen (1989) lists it as a member of the old disk population.
HD 50002 is a solitary star in the southern circumpolar constellation Volans. It is faintly visible to the naked eye with an apparent magnitude of 6.09 and is located at a distance of 708 light years. However, it is drifting further with a heliocentric radial velocity of 5.1 km/s.
HD 222806 is a suspected astrometric binary in the southern circumpolar constellation Octans. It has an apparent magnitude of 5.74, allowing it to be faintly seen with the naked eye. Parallax measurements place the system at a distance of 565 light years and it is currently receding with a heliocentric radial velocity of 21 km/s.
HD 46815 is a solitary star in the southern constellation Columba. It is faintly visible to the naked eye with an apparent magnitude of 5.4 and is estimated to be 408 light years away. However, it is receding with a heliocentric radial velocity of 32.2 km/s.
15 Delphini is a star in the equatorial constellation Delphinus. It has an apparent magnitude of 5.99, allowing it to be faintly seen with the naked eye. The star is relatively close at a distance of 99 light years but is receding with a heliocentric radial velocity of 4.1 km/s.
