suppose that a polar bear's foot has a luminosity of . what is the bolometric absolute magnitude of the bear's foot? what is the bolometric apparent magnitude of the foot at a luminosity distance of ? if a bolometer can detect the bear's foot at a maximum luminosity distance of , what is the maximum luminosity distance at which it could detect the sun? what is the maximum luminosity distance at which it could detect a supernova with ?

Answer :

The bolometric absolute magnitude of the bear's foot is M = 68.70.

Solution:

Bear's foot has a luminosity of 2 = 10 Watt

We have to find the bolometric absolute magnitude foot of the bear

we know the bolo metric absolute magnitude formula

M = -2.5 log10 (2x) —(1) will but 78.7 x 3.83×1026 20 гое 2x = Lx → refer luminosity value of L and Lx in the equation.... (i)

M = -2.5 log10 ( 10/ 78.7 x 3.83 x 10²⁶

M = -2.5 log 10 (10/301.42 x  10²⁶)

M = -2.5 -27.48

M = 68.70

We propose the radiation temperature T as a measure of circumstellar eclipses and the evolutionary development of young stellar bodies. T is the temperature of a blackbody with the same mean frequency as the observed continuum spectrum. A bolometer is an instrument used to measure radiation by measuring the temperature rise of a blackened metal strip in one of the arms of a resistance bridge.
