bolometric
- Adjective:
- Of or relating to a bolometer: Pertaining to the measurement of electromagnetic radiation, especially across a wide range of wavelengths, using a bolometer.
- Measured by or derived from a bolometer: Describing quantities, such as luminosity or magnitude, that are obtained through bolometric techniques.
- Adjective:
- The astronomer calculated the star's bolometric luminosity by measuring its total energy output across all wavelengths.
- A bolometric correction is applied to convert a visual magnitude into a measure of total radiant energy.
"Bolometric magnitude": A measure of a celestial object's total electromagnetic radiation output across all wavelengths, not just the visible spectrum.
- The star's apparent brightness is faint, but its bolometric magnitude reveals it is extremely luminous when all radiation is considered.
"Bolometric correction": The numerical difference between an object's visual (or other filtered) magnitude and its bolometric magnitude.
- Applying the correct bolometric correction is essential for accurate stellar energy budgets.
Bolometer (n): A sensitive instrument for measuring the power of incident electromagnetic radiation via the heating of a material with a temperature-dependent electrical resistance.
- The experiment used a cryogenically cooled bolometer to detect faint submillimeter waves.
Bolometrically (adv): In a manner relating to or measured by a bolometer.
- The energy flux was measured bolometrically.
- Radiometric: Pertaining to the measurement of radiant energy.
- Total-flux: Describing measurement across the entire spectrum.
This is a highly specialized scientific term. Its use is almost exclusively confined to fields like astronomy, physics, and engineering, where precise measurement of electromagnetic radiation is required. The core concept is the measurement of total radiant energy, as opposed to energy within a specific band (e.g., visual or infrared).
