how can you tell if a star is mostly made of hydrogen?
Homework Answers
We can use the spectrum of light of the star. When elements like hydrogen are present in abundant like our sun, they absorb light of specific wavelength and when light from star is observed via spectrometer, we get an absorption spectrum with a lot of black lines. Here, black lines mean the presence of certain elements such as hydrogen.
If a star is mostly made of hydrogen, we get absorption spectra with a lot of black lines.

Under some circumstances, a star can collapse into an extremely dense object made mostly of neutrons and called a neutron star. The density of a neutron star is roughly 1014 times as great as that of ordinary solid matter. Suppose we represent the star as a uniform, solid, rigid sphere, both before and after the collapse. The star's initial radius was 6.0×105 km (comparable to our sun); its final radius is 17 km. If the original star rotated once in...

Under some circumstances, a star can collapse into an extremely dense object made mostly of neutrons and called a neutron star. The density of a neutron star is roughly 10^14 times as great as that of ordinary solid matter. Suppose we represent the star as a uniform, solid, rigid sphere, both before and after the collapse. The star's initial radius was 7.0×10^5 km (comparable to our sun); its final radius is 18km . If the original star rotated once in...

A star can be approximated to a black body mostly constituted of gas with a surface temperature T. From the black body density of oscillators we can demonstrate that the power emitted in the forward direction by the star of surface area A per unit wavelength is: A exp( )-1 (Eg.1) Maximum emission Using Equation I , give an approximation of the power Permitted at short wavelengths (λ<<1). c.
