1. of, relating to, or measured by a bolometer (an instrument that detects and measures electromagnetic radiation, especially infrared radiation)
Usage: technical; astronomy and physics

Examples

• The bolometric magnitude of a star accounts for all the radiation it emits across the entire electromagnetic spectrum.
• Astronomers used bolometric measurements to study the infrared emissions from distant galaxies.
• The bolometric detector was sensitive enough to measure the faint heat signature of the exoplanet.
• Bolometric observations revealed the true luminosity of the obscured star.
• The telescope's bolometric instruments collected data on thermal radiation from the nebula.
