Mira, designation Omicron Ceti, is a red giant star estimated to be 200–400 light-years from the Sun in the constellation Cetus.
Corvus is a small constellation in the Southern Celestial Hemisphere. Its name means "crow" in Latin. One of the 48 constellations listed by the 2nd-century astronomer Ptolemy, it depicts a raven, a bird associated with stories about the god Apollo, perched on the back of Hydra the water snake. The four brightest stars, Gamma, Delta, Epsilon, and Beta Corvi, form a distinctive quadrilateral in the night sky.
R Leporis (R Lep), sometimes called Hind's Crimson Star, is a well-known variable star in the constellation Lepus, near its border with Eridanus. It is designated "R" in the chart to the right.
The descriptive term long-period variable star refers to various groups of cool luminous pulsating variable stars. It is frequently abbreviated to LPV.
Delta Corvi, also named Algorab, is a third magnitude star at a distance of 86.9 light-years from the Sun in the southern constellation of Corvus.
Chi Cygni is a Mira variable star in the constellation Cygnus, and also an S-type star. It is around 500 light years away.
RV Tauri variables are luminous variable stars that have distinctive light variations with alternating deep and shallow minima.
S Carinae is a variable star in the constellation Carina.
R Centauri is a Mira variable star in the constellation Centaurus. It is approximately 1,300 light years from Earth.
T Cephei is a Mira variable star in the constellation Cepheus. Located approximately 570 ± 40 light-years distant, it varies between magnitudes 5.2 and 11.3 over a period of around 388 days.
T Andromedae is a variable star of the Mira type in the constellation Andromeda. Like all the stars of this kind, T And is a cool asymptotic giant branch star of spectral type M4e-M7.5e, and his variability occurs periodically, with the period calculated at 281 days. The peak luminosity, however, is different every variability cycle, but can reach a peak magnitude mv=7.70.
R Reticuli is a Mira variable star in the southern constellation Reticulum. It is an aging red giant star on the asymptotic giant branch with a stellar classification that varies between M4e to M7.5e, being hottest near maximum visual magnitude. The brightness of the star varies between apparent visual magnitudes 6.35 and 14.2 with an average period of 281.08±0.58 d. The mean maximum magnitude is 7.57 and the mean minimum magnitude 13.80.
VV Corvi is a close spectroscopic binary in the constellation Corvus. It is also an eclipsing binary, varying from magnitude 5.19 to 5.34 over 3.145 days. The two stars orbit each other with a period of 1.46 days and an eccentricity of 0.088. The mass ratio of the two stars is 0.775±0.024. The primary is 1.978 ± 0.010 times as massive as the Sun, 18.253 ± 2.249 its luminosity and has 3.375 ± 0.010 the Sun's radius. The secondary is 1.513 ± 0.008 times as massive as the Sun, 4.745 ± 0.583 its luminosity and has 1.650 ± 0.008 the Sun's radius. Both are yellow-white main sequence stars of spectral type F5V, though the primary has begun expanding and cooling as it nears the end of its time on the main sequence. A tertiary companion was discovered during the Two Micron All-Sky Survey.
T Ursae Minoris is a star in the constellation Ursa Minor, located 2'30" west-southwest of 3 Ursae Minoris toward the western border of the constellation with Draco.
BH Crucis, also known as Welch's Red Variable, is a star in the constellation Crux. A long period (Mira-type) variable, its apparent magnitude ranges from 6.6 to 9.8 over 530 days. Hence at its brightest it is barely visible with the unaided eye in a rural sky. A red giant, it had been classified by SIMBAD as ranging between spectral types SC4.5/8-e and SC7/8-e, but appears to have evolved into a C-type spectrum by 2011.
V Coronae Borealis is a Mira-type long period variable star and carbon star in the constellation Corona Borealis. Its apparent magnitude varies between 6.9 and 12.6 over a period of 357 days
R Normae is a Mira variable star located near Eta Normae in the southern constellation of Norma. This is an intermediate-mass red giant star that is generating part of its energy through hydrogen fusion. Because this fusion is thought to be occurring under conditions of convection, it is generating an excess of lithium. The star ranges from magnitude 6.5 to 12.8 and has a relatively long period of 496 days. Located around 2,900 light-years distant, it shines with a luminosity 7764 times that of the Sun and has a surface temperature of 3161 K.
R Capricorni (R Cap) is a star in the constellation of Capricornus. It has an apparent visual magnitude which varies between 9.4 and 14.9. A mira variable and ageing red giant, it is in the asymptotic giant branch stage of its lifespan.
S Cassiopeiae is a Mira variable and S-type star in the constellation Cassiopeia. It is an unusually cool star, rapidly losing mass and surrounded by dense gas and dust producing masers.
V Crucis is a carbon star in the constellation Crux. A Mira variable, its apparent magnitude ranges from 8.7 to 11.1 over 376.5 days.
