Lovelace, Richard"Disk and Wind Accretion to Magnetized Neutron Stars"AST-9986936Dr. Lovelace is performing 2- and 3-dimensional simulations of disk and wind accretion of material onto rotating magnetized stars and developing the associated analytic theory. The models apply to a range of astrophysical situations where accretion is occurring, such as binary star systems where there are inclined rotating stars, magnetized neutron stars, fast stellar winds. In addition, the effects of direct accretion, magnetic inhibition of accretion, viscosity, and the so-called 'propeller mechanism' are incorporated into the models and compared to observations. This project involves a strong collaboration with colleagues in Russia, via co-PI Romanova.Funding for this project was provided by the NSF program for Stellar Astronomy & Astrophysics (AST/SAA) and the NSF International Program for the Baltic States, Bulgaria, Poland, & Independent States of the Former Soviet Union (INT).***

Lovelace，Richard“磁盘和磁性中子星星的风力积聚” AST-9986936DR。 Lovelace正在对磁盘和材料的风吸积2和3维模拟，并在旋转的磁化恒星上进行，并开发相关的分析理论。 这些模型适用于发生吸积的一系列天体物理情况，例如二进制恒星系统，那里有倾斜的旋转恒星，磁性中子恒星，快速恒星风。 此外，直接吸积，磁抑制，粘度和所谓的“螺旋桨机制”的影响被纳入模型并与观察结果相比。 该项目涉及与俄罗斯的同事通过Co-Pi Romanova进行强有力的合作。为该项目提供资金，由NSF恒星天文学和天体物理学计划（AST/SAA）和NSF国际计划和波罗的海国家，保加利亚，波兰，波兰，波兰，波兰，波兰，前苏联联盟（INT）（INT）（INT）（INT）。
