In a given constellation, the first variable stars discovered were designated with letters R through Z
The current naming system is:-
* Stars with existing Greek letter designations are not given new designations. * Otherwise, start with R and go through Z. * Continue with RR...RZ, then use SS...SZ, TT...TZ and so on until ZZ. * Use AA...AZ, BB...BZ, CC...CZ and so on until reaching QZ, omitting J in both the first and second positions. * Finally give up on the Roman alphabet after 334 combinations of letters and start naming stars with V335, V336, and so on.

What is the tool used to identify stars and constellations is called an?
it is called an star chart
What two variables are used to classify stars?
The first variable that is used to classify stars is its ionization state which can measure the photosphere's temperature and density. This information is gathered by splitting the light from a star with a prism and observing the resulting spectrum that includes absorption lines. Luminosity is another variable used; it is based on the width of absorption lines.
Cepheid variable stars have been used to determine the?
1)placing cosmological constraints on the expansion of the Universe through the determination of distances to galaxies 2)to measure many characteristics of our galaxy and our relationship to it
Why did you use constellations?
Constellations are used to identify groups of stars in the sky. It is easier to refer to the 88 constellations than to remember the location of each star. It's like dividing a city into neighborhoods, instead of houses.
Can ultraviolet light be used to identify willemite?
Yes. Ultraviolet light can be used to identify willemite. In fact willemite continues to glow even after the ultraviolet light is turned off.
What scientific term is used to identify the factor that is changed in an experiment?
variable
What is a two word naming system used to name various species?
Usually the genus and species names are used to identify different organisms.
Who first used the word variable to identify a letter standing for a number?
Gottfried Wilhelm Leibniz
What is the tool used to identify stars and constellations is called an?
it is called an star chart
What does an IVCDV chart mean?
Helps students organize identify independent variable, dependent variable, and constants in an experimental design. This information is then used to write an if/then statement for a hypothesis.
What method did flamsteed used to name the stars?
The method that Flamsteed used to name the stars were similar to the Bayer System of Nomenclature, instead that they used numbers instead of Greek letters. Each star is assigned a number and the Latin genitive of the constellation it lies in. By this method, Flamsteed's designation contained 2,554 stars.
What is the purpose of an chart?
Helps students organize identify independent variable, dependent variable, and constants in an experimental design. This information is then used to write an if/then statement for a hypothesis.
Can keyword be used as variables?
No, any keyword could be used as a identifier (a method, class or variable name). These keywords have a special meaning in the language and the compiler can not identify if they are used as a variable name or as a keyword,
What is dependant variable?
A dependant variable is a term used in science to identify the response that is measured in an experiment. When a researcher conducts an experiment, he is interested in the outcome, defined as the dependent variable.
What are variables used to classify stars?
The first variable that is used to classify stars is its ionization state which can measure the photosphere's temperature and density. This information is gathered by splitting the light from a star with a prism and observing the resulting spectrum that includes absorption lines. Luminosity is another variable used; it is based on the width of absorption lines.
Are RR Lyrae stars and RR Lyrae variables different?
RR Lyrae variables are variable stars often used as standard candles. RR Lyrae are pulsating horizontal branch stars.
Why is neo used in naming common nomenclature of organic compounds?
Neo is used in the naming of the common nomenclature or organic compounds for easier identification.
