These huge dying stars are formed with between nine and 40 times the mass of the Sun. When a star becomes a red supergiant, its atmosphere extends outward so it becomes large and luminous, but low-density. Antares now has a mass about 12 times that of the Sun and a diameter about 700 times larger than the Sun\u2019s. It is thought that it started life with a mass more like 15 times that of the Sun, and has shed three solar-masses of material during its life.<\/p>\n<p><a class=\"anchor\" name=\"2\"><\/a>[2] The velocity of material towards or away from Earth can be measured by the\u00a0<a href=\"https:\/\/en.wikipedia.org\/wiki\/Doppler_effect\">Doppler Effect<\/a>, which shifts spectral lines either towards the red or blue ends of the spectrum, depending on whether the material emitting or absorbing light is receding from or approaching the observer.<\/p>\n<p><a class=\"anchor\" name=\"3\"><\/a>[3] Convection is the process whereby cold material moves downwards and hot material moves upwards in a circular pattern.
