Bolometric magnitude is a term that is commonly used in the field of astronomy. It is a measure of the total amount of energy that a celestial object emits across all wavelengths of the electromagnetic spectrum. This article will provide a detailed definition and meaning of bolometric magnitude, its origin, associations, synonyms, antonyms, and example sentences.
Definitions
Bolometric magnitude is defined as the measure of the total energy emitted by a celestial object across all wavelengths of the electromagnetic spectrum. It is expressed in units of watts per square meter (W/m²). The bolometric magnitude of a celestial object is calculated by integrating the flux density of the object over all wavelengths.
Origin
The term “bolometric magnitude” was first coined by the American astronomer, Henry Norris Russell, in the early 20th century. Russell was one of the pioneers in the field of astrophysics and made significant contributions to the study of stars and their evolution.
Meaning in different dictionaries
The term “bolometric magnitude” is not commonly found in general dictionaries. However, it can be found in specialized dictionaries such as the “Dictionary of Astronomy” by Ian Ridpath, where it is defined as “the magnitude of a star measured over all wavelengths of the electromagnetic spectrum”.
Associations
Bolometric magnitude is associated with the study of stars and other celestial objects. It is used by astronomers to determine the total amount of energy emitted by a star or galaxy, which is an important factor in understanding their properties and evolution.
Synonyms
There are no commonly used synonyms for bolometric magnitude. However, the term “bolometric luminosity” is sometimes used interchangeably with bolometric magnitude.
Antonyms
There are no commonly used antonyms for bolometric magnitude.
The Same Root Words of Bolometric Magnitude
The root words of “bolometric magnitude” are “bolometric” and “magnitude”. Bolometric refers to the measurement of energy across all wavelengths of the electromagnetic spectrum, while magnitude refers to the brightness of a celestial object.
Example Sentences
- The bolometric magnitude of the sun is approximately 3.8.
- Astronomers use bolometric magnitude to determine the total energy emitted by a star.
- The bolometric magnitude of a galaxy can provide valuable information about its properties and evolution.
