the current mass of a star is the same as the mass it had when it first became a protostarTrue or false astronomy question?
False. Stars burn their nuclear fuel constantly and emit new atoms out into space and radiations of many types. All this travels away from the star in its stellar wind and it will account for as much as 75% of its initial mass over time, depending of the type of star.
The reason stars die out is because they lose their mass after burning enough of its fuel; its density becomes lower and the pressure in the nucleus drops and it cannot produce nuclear reactions anymore.True or false astronomy question?
False. The fusion process coverts mass into energy.
False.
False. some mass has been lost through fusion.
