  2. Main sequence turnoff - Wikipedia

    en.wikipedia.org/wiki/Main_sequence_turnoff

    The turnoff point for a star refers to the point on the HertzsprungRussell diagram where it leaves the main sequence after its main fuel is exhausted – the main sequence turnoff. By plotting the turnoff points of individual stars in a star cluster one can estimate the cluster's age .

  3. Hertzsprung–Russell diagram - Wikipedia

    en.wikipedia.org/wiki/HertzsprungRussell_diagram

    This type of diagram could be called temperature-luminosity diagram, but this term is hardly ever used; when the distinction is made, this form is called the theoretical HertzsprungRussell diagram instead. A peculiar characteristic of this form of the H–R diagram is that the temperatures are plotted from high temperature to low temperature ...

  4. Robust Regression and Outlier Detection - Wikipedia

    en.wikipedia.org/wiki/Robust_Regression_and...

    Robust regression methods can fit a curve to the main sequence, the central curve in this diagram, without being strongly influenced by the groups of stars far from the main sequence. Linear regression is the problem of inferring a linear functional relationship between a dependent variable and one or more independent variables , from data sets ...

  5. Blue straggler - Wikipedia

    en.wikipedia.org/wiki/Blue_straggler

    Sketch of HertzsprungRussell diagram of a globular cluster, showing blue stragglers. A blue straggler is a type of star that is more luminous and bluer than expected. . Typically identified in a stellar cluster, they have a higher effective temperature than the main sequence turnoff point for the cluster, where ordinary stars begin to evolve towards the red gi

  6. Stellar birthline - Wikipedia

    en.wikipedia.org/wiki/Stellar_birthline

    The stellar birthline is a predicted line on the HertzsprungRussell diagram that relates the effective temperature and luminosity of pre-main-sequence stars at the start of their contraction. [1] Prior to this point, the objects are accreting protostars , and are so deeply embedded in the cloud of dust and gas from which they are forming ...

  7. Stellar isochrone - Wikipedia

    en.wikipedia.org/wiki/Stellar_isochrone

    In stellar evolution, an isochrone is a curve on the Hertzsprung-Russell diagram, representing a population of stars of the same age but with different mass. [1] The Hertzsprung-Russell diagram plots a star's luminosity against its temperature, or equivalently, its color. Stars change their positions on the HR diagram throughout their life.

  8. Herbig Ae/Be star - Wikipedia

    en.wikipedia.org/wiki/Herbig_Ae/Be_star

    In the HertzsprungRussell diagram, Herbig Ae/Be stars are located to the right of the main sequence. They are named after the American astronomer George Herbig, who first distinguished them from other stars in 1960. The original Herbig criteria were: Spectral type earlier than F0 (in order to exclude T Tauri stars),

  9. Blue giant - Wikipedia

    en.wikipedia.org/wiki/Blue_giant

    In the standard HertzsprungRussell diagram, these stars lie above and to the right of the main sequence. The term applies to a variety of stars in different phases of development, all evolved stars that have moved from the main sequence but have little else in common, so blue giant simply refers to stars in a particular region of the HR ...
