WebAll steps. Final answer. Step 1/3. So, the solutions to the given questions are as follows: Based on the general evolution of stars that experience a helium flash. The first dot on the left side of the Z-type curve likely represents the onset of helium fusion in the star's core, which would correspond to the option "helium to carbon fusion begins." WebLuminosity of stars if often expressed in units of the Sun's luminosity (L = 3.9 x 10 26 Joules/s). The HR diagram spans a rather large range in luminosity, from 10-4 L on the low end to as much as 10 6 L on the high end.

WebThe mass of a star determines exactly where it falls on the main sequence. As Figure 21.12 shows, massive stars on the main sequence have high temperatures and high luminosities. Low-mass stars have low temperatures and low luminosities. Objects of extremely low mass never achieve high-enough central temperatures to ignite nuclear reactions. WebOct 7, 2024 · You can use an HR diagram along with calibrated evolutionary models to find the distance (and in some cases, mass and age) of individual stars.
