Match the following item to the correct response Star Spectra Choose Show While Seventeen och del the same 10 Tenge Choose Hum Sodium High atmospheric pressures in a star cause spectral lines to be broadened, or 'smeared out Giant stars, which have relatively low atmospheric pressures, are characterized by narrow spectral lines. If a star is moving away from an observer, spectral lines are redshifted, or shifted toward the red end of the spectrum An approaching star is blueshifted A star orbited by a large planet will move in a small chicle. The will cause its spectrum to be slightly redshifted part of the time and bluechifted at other times Binary stars are pairs of stars that orbitone another. Their presence is indicated by two spectra that thift in opposite directions Cephold variable stars change their brightness in a regular cycle. Gas pressure builds up, causing the stars to expand quickly. When the pressure is released, the star contracts, and the intensity of some spectral lines may decrease A nebula is an enormous cloud of gas and dust in which stars are born, Most nebulae produce an emission spectrum, which is characterized by bright lines of color against a dark background. The bright lines in an emission spectrum correspond to the dark lines in an absorption spectrum Choose Mam Calam Choose T Choose
