Phys. Rev. Lett. 57, 2466–2469 (1986)How Large Can a Star Be?Received 17 June 1986; published in the issue dated 10 November 1986 In a recent article Schoen and Yau develop an inequality which shows that there exists a relationship between the minimum energy density ρ0 in a star and the size R of the star, of the form ρ0R2≤π/6. This article shows that this inequality is valid for two different measures of the size of the star and conjectures that the inequality can be improved to ρ0R2≤3π/32. © 1986 The American Physical Society URL:
