Exempel på hur man kan använda CASSIOPEIAE i en mening

• The constellation hosts some of the most luminous stars known, including the yellow hypergiants Rho Cassiopeiae and V509 Cassiopeiae and white hypergiant 6 Cassiopeiae.
• β Canis Minoris has long been suspected of variability, and in 1977 it was classified as a γ Cassiopeiae variable in the General Catalogue of Variable Stars.
• The other components are Beta Cassiopeiae (Caph), Kappa Cassiopeiae, Alpha Cassiopeiae (Schedar) and Lambda Cassiopeiae.
• Though listed as the "alpha star" by Johann Bayer, α Cas's visual brightness closely matches the 'beta' (β) star in the constellation (Beta Cassiopeiae) and it may appear marginally brighter or dimmer, depending on which passband is used.
• 28, it is one of the five stars which make up the 'W' of Cassiopeia, adjacent to the just brighter Schedar (Alpha Cassiopeiae).
• Rho Cassiopeiae is the second brightest yellow hypergiant in the sky, the brightest being V382 Carinae, although Rho Cassiopeiae is mostly visible only in the northern hemisphere and V382 Carinae mostly only in the southern hemisphere.
• The star Delta Cassiopeiae also bore the traditional names Ruchbah or Rukbat, from the Arabic word ركبة rukbah meaning "knee".
• The WGSN approved the name Sadalmelik for Alpha Aquarii (WDS J22058-0019 A) on 21 August 2016, and it is now so included in the List of IAU-approved Star Names (Delta Cassiopeiae was given the name Ruchbah).
• The General Catalogue of Variable Stars (GCVS) categorises γ Cassiopeiae stars as eruptive variables and describes them as rapidly-rotating B class giants or subgiants, although many of them are main sequence stars.
• CHARA directly imaged multiple stars, such as Regulus, Rasalhague, Altair, Alderamin and Beta Cassiopeiae to measure the flattened shape of these rapidly rotating stars.
• Mu Cassiopeiae is given as a standard star for the spectral class G5Vb, although it is frequently described as a subdwarf, meaning it has a luminosity below that expected for a G5 main sequence star.
• He thus began an aggressive research program that produced a series of papers in the Astrophysical Journal on eclipsing binaries Lambda Tauri, Algol, 1H Cassiopeiae (HR 8926), ellipsoidal variables π5 Orionis, and b Persei, and Nova Aquilae (V603 Aquilae) in 1918.
• Notable examples of hypergiants include the Pistol Star, a blue hypergiant located close to the Galactic Center and one of the most luminous stars known; Rho Cassiopeiae, a yellow hypergiant that is one of the brightest to the naked eye; and Mu Cephei (Herschel's "Garnet Star"), one of the largest and brightest stars known.
• TZ Cassiopeiae was reported as being variable by Williamina Fleming and published posthumously in 1911.
• The object passed near the stars Gamma Geminorum, Eta Geminorum, Capella, 172 Camelopardalis, 50 Cassiopeiae, Gamma Cephei, Psi Draconis, 16 Draconis, Psi Herculis, Kappa Coronae Borealis and Delta Coronae Borealis.
• The General Catalogue of Variable stars includes this system as a variable similar to but not properly of the Gamma Cassiopeiae type, with the variable star designation QV Telescopii, indicating that it is the 330th confirmed variable star (excluding stars with Bayer designations) in the constellation Telescopium.
• Cepheus OB1 contains dozens of O and B class stars, but the brightest members are cool supergiants and hypergiants such as V509 Cassiopeiae (HR 8752) and RW Cephei.
• It lies a few arcminutes to the south-east of the bright yellow-hued giant star Beta Cassiopeiae, officially named Caph.
