Evolved stars of masses similar or slightly greater than that of the sun evolve through the so-called red giant region. They are cool, luminous stars, and they lose mass via strong stellar winds. The winds form circumstellar shells of gas and dust, known as planetary nebulae. The Principal Investigator proposes to study this kind of mass loss and the formation of planetary nebulae. Both observations and theory will be part of this work. The emphasis will be on the physics and chemistry of the mass loss process.

与太阳相似或稍大的质量的恒星通过所谓的红色巨型区域进化。 它们是凉爽，发光的恒星，并且由于强风而失去质量。 风形成了气体和灰尘的壳壳，称为行星星云。 主要研究者建议研究这种质量损失和行星星云的形成。 观察和理论都将成为这项工作的一部分。 重点将放在群众损失过程的物理和化学上。
