![]() White dwarfs will go supernova once reaching 1.39 solar masses, while these remnant cores are about 1.4 solar masses. The mass of the supernova remnants of these 11.5 solar mass stars is a little over the Chandrasekhar limit. I will perform some tests with timewarp on stars in regards to that immortal star issue and report my findings to you on the other thread. Have you tried flipping the "Radius From Composition" switch off and on for that star and seeing if it explodes? I am confused why yours stayed the same despite increasing the mass so much. But you can clearly see that its radius, temperature and luminosity have changed and are in proportion to any change in mass. This time I managed to get Polaris to 11.7 solar masses before it went supernova. In my case, if I add onto a star's mass, its radius, temperature and luminosity all change. Those three parameters should have changed with any adjustment in mass. When you increased its mass, the star's radius, temperature and luminosity all stayed the same. "Radius From Composition" was switched on when you upped its mass, yes? Your Polaris' radius, surface temperature and luminosity are the same as the default 4.5 solar mass Polaris. Although, something looks a bit odd with your star's parameters. I tested with Polaris, but unfortunately it still doesn't allow me to increase it past that mass. If anyone has further information regarding this phenomena willing to share, thank you in advance for your assistance. To supplement this, I have included a video of the replication process. ![]() A supernova event should occur at 11.5 solar masses. ![]() To do so, place down any random star under 11.5 solar masses, set its age to 0, ensure "Radius From Composition" is turned on, and then up its mass through any means. In real life, can't giant stars grow to over 11.5 solar masses without exploding, given that its fuel isn't exhausted yet? I don't recall anything out of the ordinary occurring to stars at this mass in real life, so I am fairly sure that this is not an accurate simulation of what is meant to happen. I find this issue rather strange and I'm not too sure whether it really is a bug. While it is true that I could just create more massive stars with "Radius From Composition" off without having to worry about them exploding, I feel as if the parameters would not be proportional to each other or realistic if I manually plugged them in. Before 11.5 solar masses, all these parameters are proportional with each other even with "Radius From Composition" switched off, but do not change at all after this point with it switched off. However, once this option is switched off, luminosity, temperature, density and radius are no longer simulated past 11.5 solar masses. If switched off, stars can pass this point. In fact, this issue only occurs if the option "Radius From Composition" is switched on. But again, no matter how mass is added, it always explodes once reaching 11.5 solar masses.Ī star such as R136a1—which is far beyond 11.5 solar masses—doesn't instantly explode when I place it down, but it does do so if I switch off and then switch on the "Radius From Composition" button. I have also attempted different ways of increasing a star's mass, from plugging in numbers in the body tab to launching material at it. But even when I set a star's age to 0 years and then increase its mass from this point onwards, it still cannot grow more massive than 11.5 solar masses. ![]() Therefore, I have suspected that this effect may be because a preexisting star's age is already too old for such giant stars to theoretically exist. It doesn't matter if I up the mass of a known star or a random main sequence star, the critical point is always around 11.5 solar masses.Īny star placed down has an assigned age. When I attempt to increase any star's mass, once they reach about 11.5 solar masses, the star explodes in a supernova. This is the most bizarre issue I have ever encountered in US 2.
