TT Corvi (TT Crv) is a semiregular variable star in the constellation Corvus. It is a red giant of spectral type M3III and average apparent magnitude 6.48 around 923 light years distant. [2] It shines with a luminosity approximately 993 times that of the Sun and has a surface temperature of 3630 K. [3]
15 Arietis is a single variable star in the northern constellation of Aries. 15 Arietis is the Flamsteed designation; it also bears the variable star designation AV Arietis. It has an apparent visual magnitude of 5.74, which is just bright enough to be visible to the naked eye from dark suburban skies. An annual parallax shift of 5.84 mas corresponds to a physical distance of approximately 560 light-years from Earth. At that distance, the star's brightness is reduced by 0.33 in magnitude because of extinction from interstellar gas and dust.
Beta Camelopardalis, Latinised from β Camelopardalis, is the brightest star in the northern constellation of Camelopardalis. It is bright enough to be faintly visible to the naked eye, having an apparent visual magnitude of 4.02. Based upon an annual parallax shift of 3.74 mas as seen from Earth, it is located roughly 870 light-years from the Sun. It is moving closer with a radial velocity of −1.90 km/s and is most likely a single star.
2 Centauri is a single star in the southern constellation of Centaurus, located approximately 183 light-years from Earth. It has the Bayer designation g Centauri; 2 Centauri is the Flamsteed designation. This object is visible to the naked eye as faint, red-hued star with an apparent visual magnitude of 4.19. It is moving away from the Earth with a heliocentric radial velocity of +41 km/s. The star is a member of the HR 1614 supercluster.
Tau4 Eridani is a binary star system in the constellation Eridanus. It is visible to the naked eye with an apparent visual magnitude of 3.65. The distance to this star can be estimated using the parallax method, which yields a value of roughly 300 light years.
WASP-3 is a magnitude 10 yellow-white dwarf star located about 800 light-years away in the Lyra constellation. It appears to be variable; it "passed from a less active to a more active state between 2007 and 2010".
HD 187734 is double star in the equatorial constellation of Aquila. The primary is a magnitude 6.6 giant star, while the companion is a magnitude 9.4 A-type main sequence star. As of 2014, the pair had an angular separation of 5″ along a position angle of 99°.
HD 157753 is giant star in the southern constellation of Ara. It may be an astrometric binary, and it has a faint, magnitude 13 companion at an angular separation of 31.5″ along a position angle of 356°.
HD 156091 is a double star in the southern constellation of Ara. The primary is a sixth magnitude giant star with stronger than normal lines of carbon, nitrogen, and barium in its spectrum. The companion is a 13th magnitude star at an angular separation of 27.4″ along a position angle of 275°, as of 2000.
45 Draconis is a single star located in the northern circumpolar constellation of Draco, around 3,500 light years from the Earth. 45 Draconis is the Flamsteed designation, while it has the Bayer designation of d Draconis. This object is visible to the naked eye as a faint, yellow-white hued star with an apparent visual magnitude of 4.78. Radial velocity measurements indicate it is moving closer to the Sun at the rate of −12.5 km/s.
7 Ceti is a single, variable star in the equatorial constellation of Cetus. It has the variable star designation AE Ceti. The star is visible to the naked eye with a baseline apparent visual magnitude of 4.44. Based upon an annual parallax shift of only 7.3 mas, it is located roughly 450 light years away. It is moving closer to the Sun with a heliocentric radial velocity of −23 km/s. Eggen (1965) listed it as a probable member of the Wolf 630 group of co-moving stars.
F Hydrae, also known as HD 74395, is a star in the constellation Hydra with an apparent magnitude is 4.64. It was catalogued as 31 Monocerotis, but this name is now rarely used since the star is now within the boundaries of Hydra. It is a low mass yellow supergiant around a thousand times brighter than the sun and five times as massive.
Phi2 Hydrae, Latinized from φ2 Hydrae, is a star in the constellation Hydra. It originally received the Flamsteed designation of 1 Crateris before being placed in the Hydra constellation. Based upon an annual parallax shift of 4.31 mas as seen from Earth, it is located roughly 760 light years from the Sun. The star is faintly visible to the naked with an apparent visual magnitude of 6.09. It forms a triangle with the fainter φ1 Hydrae and the brighter φ3 Hydrae, between μ Hydrae and ν Hydrae.
Omicron1 Orionis is a binary star in the northeastern corner of the constellation Orion. It is visible to the naked eye with an apparent visual magnitude of 4.7. Based upon an annual parallax shift of 5.01±0.71 mas, it is located approximately 650 light years from the Sun. At that distance, the visual magnitude of the star is diminished by an interstellar absorption factor of 0.27 due to intervening dust.
9 Pegasi is a supergiant star in the constellation Pegasus. Its apparent magnitude is 4.35.
30 Piscium is a solitary variable star in the zodiac constellation of Pisces. It is visible to the naked eye with an apparent visual magnitude of 4.37. Its calculated mid-value of antiposed parallax shift as the Earth moves around the Sun of very roughly 7.88 mas, makes it around 410 light years away. Its net movement in the present epoch is one of moving closer – radial velocity is −12 km/s.
HD 85622 is a binary star system in the southern constellation of Vela. It is visible to the naked eye with an apparent visual magnitude of 4.58. The distance to HD 85622 can be estimated from its annual parallax shift of 4.3 mas, yielding a value of 750 light years. It is moving further from the Earth with a heliocentric radial velocity of +8 km/s.
35 Cygni is a spectroscopic binary star in the constellation Cygnus. Its apparent magnitude is 5.18. Located around 1,000 parsecs (3,300 ly) distant, its primary is a yellow supergiant of spectral type F6Ib, a massive star that has used up its core hydrogen and is now fusing heavier elements.
AK Pyxidis is a semiregular variable star located in the constellation Pyxis. It varies between magnitudes 6.09 and 6.51, pulsating to multiple periods simultaneously of 55.5, 57.9, 86.7, 162.9 and 232.6 days. Located around 1228 light-years distant, it shines with a luminosity approximately 1500 times that of the Sun and has a surface temperature of 3410 K.
V372 Carinae is a single star in the southern constellation of Carina. Located around 1300 light-years distant. It shines with a luminosity approximately 1742 times that of the Sun and has a surface temperature of 14132 K. It is a Beta Cephei variable.
AF Columbae, also known as HD 42682, is a solitary, red hued variable star located in the southern constellation Columba, the dove. It has an apparent magnitude that fluctuates between 5.6 and 5.71. Nevertheless, it is faintly visible to the naked eye. Parallax measurements from the Gaia spacecraft place the star relatively far at a distance of 820 light years. However, it is approaching the Solar System with a poorly constrained radial velocity of −19 km/s.
