101Laguna de Hertzsprung — En astronomía se llama Laguna de Hertzsprung (en inglés Hertzsprung Gap) a una región del diagrama de Hertzsprung Russell en la que se encuentran muy pocas estrellas. Su nombre se debe a Ejnar Hertzsprung, quien por primera vez observó la… …

103Color–color diagram — In astronomy, color–color diagrams are a means of comparing the apparent magnitudes of stars at different wavelengths. Astronomers typically observe at narrow bands around certain wavelengths, and objects observed will have different brightnesses …
104Hertzsprung–Russell diagram — Hertzsprung–Russell diagram[1] with 22,000 stars plotted from the Hipparcos catalog and 1,000 from the Gliese catalog of nearby stars. Stars tend to fall only into certain regions of the diagram. The most predominant is the diagonal, going from… …
105Dark-energy star — A dark energy star is a hypothetical compact astrophysical object, which a minority of physicists feel might constitute an alternative explanation for observations of astronomical black hole candidates. Dark energy is invisible to the human eye;… …
106Dark star (Newtonian mechanics) — This article is about astronomical objects described by Newtonian mechanics. For the modern concept based on dark matter, see dark star (dark matter). For the modern concept based on dark energy, see dark energy star. A dark star is a theoretical …
107Dredge-up — refers to a period in the evolution of a star where a surface convection zone extends down to the layers where material has undergone nuclear fusion. As a result, the fusion products are mixed into the outer layers of the stellar atmosphere and… …
108Stellar kinematics — is the study of the movement of stars without needing to understand how they acquired their motion. This differs from stellar dynamics, which takes into account gravitational effects. The motion of a star relative to the Sun can provide useful… …
109List of proper names of stars — This is a list of proper names for stars, mostly derived from Arabic and Latin. See also the list of stars by constellation, which gives variant names, derivations, and magnitudes. Of the roughly 10,000 stars visible to the naked eye, only few… …
110North polar sequence — The North polar sequence is a group of 96 stars that was used to define stellar magnitudes and colors. The cluster of stars lies within two degrees of the Northern Celestial pole, which makes them visible to everyone on the northern hemisphere.… …
