Hard to say for certain. We’ve never witnessed the death of a star up close before, and it’s difficult to know exactly how much carbon is left, and the time left depends very strongly on the fraction of carbon left, the exact mass of the star, and even the rotational velocity of the star. There were four models evaluated, and presented in Table 2 of the paper, and if we connect this to Figure 6 we can get a rough estimate of the time remaining. From the lower values in models A and B we are close to only 10 years left, but the largest value in D is closer to almost 100 years left. The model C corresponds to about 30 or 40 years left. Though this interpretation is from “eyeballing” the graphs, not any real calculations.
