The scientific problems in the software

There are some scientific problems in the space engine. For example, as we all know, the O-type main stars are more than 15 times of sun's weight but in the space engine I've found a star with merely 7 times of sun's weight as O-type main stars. What's more, the globular clusters should be more than 5 billion years old so it is obvious there is no OB type main stars in the globular clusters however there are some OB-type main stars that are not Blue stragglers from the globular clusters in the space engine. I look forward to the modification of these problems in the newer state of the software, which will make the space engine more rigorously

Why they can't be Blue Stragglers? because they have planets?

I don't have time now to check but I suspect there have to be very massive O-type stars in the engine. For example, a user found this star that has more than 75 solar masses. It's not a blue star but I don't think those are limited either to non realistic masses. Maybe I'm wrong

Just to be clear, blue stragglers can almost certainly have planets. http://oklo.org/2011/02/27/blue-straggler-planets/

(man how I've wanted to cite systemic for ages; it's an awesome blog)

What is its surface temperature?
