Boson star at finite temperature

Understand

By using a simple thermodynamical method we confirm the finding of Chavanis and Harko that stable Bose-Einstein condensate stars can form.

• However, by using a thermodynamically consistent boson equation of state, we obtain a less massive Bose-Einstein condensate star compared to the one predicted by Chavanis and Harko.
• We also obtain that the maximum mass of a boson star is insensitive to the change of matter temperature.
• However, the mass of boson star with relatively large radius depends significantly on the temperature of the boson matter.
