Dopplereltolódással
Dopplereltolódással refers to the Doppler effect as observed in the context of astronomical observations, specifically the shift in the frequency or wavelength of light or other electromagnetic radiation emitted by celestial objects due to their relative motion. When a celestial object is moving towards an observer, the observed wavelength of its emitted radiation is shorter than the emitted wavelength, a phenomenon known as blueshift. Conversely, if the object is moving away from the observer, the observed wavelength is longer, resulting in a redshift.
This Dopplereltolódással is a fundamental tool in astrophysics, providing crucial information about the velocities of stars,
Furthermore, Dopplereltolódással can be used to detect the presence of exoplanets. As a planet orbits a star,
