Exempel på hur man kan använda SUBGIANT i en mening

• This type is usually created in a close binary star system consisting of a white dwarf and either a main sequence, subgiant, or red giant star.
• The brightest star in the constellation is Alpha Telescopii, a blue-white subgiant with an apparent magnitude of 3.
• This object has a stellar classification of G4 V-IV, being rather unusually bright for a main sequence star of its type and thus may be just starting to evolve into the subgiant phase.
• At higher masses the stars would pulsate as Classical Cepheid variables while crossing the instability strip, but massive subgiant evolution is very rapid and it is difficult to detect examples.
• The primary star of the system (catalogued as Gliese 777 A) is a yellow subgiant, a Sun-like star that is ceasing fusing hydrogen in its core.
• However, Hiltner, Garrison, and Schild (1969) listed it with a classification of B9 IV, suggesting it may be a more evolved subgiant star.
• Based upon their estimated parameters, Kaler (2008) suggests that θ Aql A is actually a subgiant star, while θ Aql B is a main sequence star.
• With a stellar classification of B2 IV/V, it appears as a B-type main-sequence star intermixed with traits of an evolving subgiant star.
• The primary, component A, is a blue-white hued B-type main-sequence or subgiant star with an apparent magnitude of +4.
• Detailed study of the spectrum suggests that the disparity is due to gravity darkening which makes the subgiant spectrum appear similar to a main-sequence star.
• The companion, υ Carinae B, is a giant star with a classification of B7 III, although Mandrini and Niemela (1986) suggested it may be a subgiant star with a classification of B4–5 IV.
• In March 2013, it was announced that resolved images of at least one dust disk surrounding Kappa Coronae Borealis were captured, making it the first subgiant to host such circumstellar belt.
• Levenhagen and Leister (2006) class it as a B9 IVe star, which would suggest it has already evolved into a subgiant star.
• HD 140283 (also known as the Methuselah star) is a metal-poor subgiant star about 200 light years away from the Earth in the constellation Libra, near the boundary with Ophiuchus in the Milky Way Galaxy.
• At the center there is an evolved G-type star (IN Comae Berenices) that is often classified as a giant star or a subgiant, as well as a hot O-type subdwarf or white dwarf that is responsible for ionizing the nebula.
• YY Mensae has a stellar classification of K1 III/IVe, indicating an evolved red giant with the blended luminosity class of a giant star and a subgiant.
