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).***

理查德·洛夫莱斯：“磁化中子星的盘和风吸积”，AST-9986936。洛夫莱斯正在对旋转磁化恒星上物质的圆盘和风吸积进行二维和三维模拟，并发展相关的分析理论。这些模型适用于一系列发生吸积的天体物理情况，例如双星系统中存在倾斜旋转的恒星、磁化的中子星和快速的恒星风。此外，模型还考虑了直接吸积、吸积磁抑制、粘性和所谓的“螺旋桨机制”的影响，并与观测结果进行了比较。该项目涉及与俄罗斯同事的密切合作，通过共同参与皮罗曼诺夫。该项目的资金由NSF恒星天文和天体物理学计划(AST/SAA)和NSF波罗的海国家、保加利亚、波兰和前苏联独立国家国际计划(INT)提供。
