← ScienceWhich effect on stellar spectra results because gravity emains locally equivalent to accelerating frames?
A)Gravitational redshift of spectral lines✓
B)Increased line broadening from turbulence
C)Blueshifting from relativistic beaming
D)Emission line increase in intensity
💡 Explanation
The gravitational redshift of spectral lines occurs because photons lose energy escaping a gravitational field, an effect indistinguishable from the Doppler shift therefore showing lower frequency; rather than increased broadening due to turbulence in a different mechanism.
