How does the Doppler technique work?
Space and AstronomyDoppler spectroscopy detects periodic shifts in radial velocity by recording variations in the color of light from the host star. When a star moves towards the Earth, its spectrum is blueshifted, while it is redshifted when it moves away from us.Doppler spectroscopyDoppler spectroscopyThe radial velocity of an object with respect to a given point is

What point does the least squares regression line pass through?
Space and AstronomyEvery least squares line passes through the middle point of the data. This middle point has an x coordinate that is the mean of the x values and a y coordinate that is the mean of the y values. What point will the regression line always go through? Now it turns out that the regression
